To make sure the anabolic steroids we offer are of the highest quality and contain the correct amount of active compounds, we have collected laboratory tests for the anabolic steroids we offer. We have started with the most popular products, yet we aim to add test for all of the products we carry.
Sibutramine hydrochloride is a selective serotonin and noradrenalin re-uptake inhibitor used for the medical management of obesity.This pharmaceutical is intended to be an adjunct to a reduced calorie diet, which will help increase weight loss compared to that achieved with modifying food intake alone. Sibutramine hydrochloride is not advertised as a rapid acting drug, but instead one that fosters slow, safe, and steady losses in fat mass which are maintained long-term.
Phentermine hydrochloride is a sympathomimetic stimulant of the amphetamine family. Like other amphetamine derivatives, it is categorized as an anorectic (appetite suppressing) agent. Phentermine is commonly prescribed as a weight loss aid in obese patients. It is typically used for short periods of time (less than 12 weeks), and as an adjunct to support an ongoing exercise and dieting regimen. The main focus is to curb the desire to eat, thereby reducing the total caloric intake. Although the data seems to vary from trial to trial, much of it supports at least a modest additional loss of fat mass with the use of phentermine hydrochloride. Athletes and bodybuilders use phentermine hydrochloride for the same purpose, typically when weight loss is required for physique remodeling or competition.
Exemestane is a steroidal suicide aromatase inhibitor. It is very similar in structure and action to formestane, although it is significantly more potent in comparison. As a class of drugs, aromatase inhibitors offer an anti-estrogenic effect by blocking the enzyme responsible for synthesizing estrogens. Exemestane is approved by the FDA for the treatment of breast cancer in women, specifically in post-menopausal patients whose cancer has progressed following therapy with tamoxifen. Male bodybuilders and athletes often use the drug for nonapproved purposes, namely to counter the estrogenic side effects associated with the use of aromatizable anabolic/androgenic steroids. This may include gynecomastia, fat buildup, and water retention. In some instances aromatase inhibitors may also assist this group with the loss of body fat and increases in muscular definition. Exemestane is one of the most potent aromatase inhibitors presently available. The most commonly cited data (found in the Aromasin packaging insert) reports a lowering of serum estrogen levels by 85% on average in clinical studies with women.
Anastrozole is an anti-estrogenic drug developed for the treatment of advanced breast cancer in women. Specifically, this agent is the first in a newer class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen in the body. Since many forms of breast cancer cells are stimulated by estrogen, reducing levels of this hormone in the body may retard the progression of the disease. This is also the fundamental use of tamoxifen citrate (Nolvadex), except Nolvadex blocks the action of estrogen at the receptor, not its actual endogenous production. The effects of anastrozole can be very substantial, with a daily dose of 1 mg (commonly 1 tablet) capable of producing estrogen suppression greater than 80% in treated patients. With the powerful effect this drug has on hormone levels, it is usually only prescribed to post-menopausal women. Side effects like hot flashes and hair thinning can present themselves during therapy, and would be much more severe in pre-menopausal patients. For the steroid-using male athlete, anastrozole is applied to minimize the side effects associated with elevated estrogen levels secondary to anabolic/androgenic steroid use. In comparison with traditional methods such as Nolvadex and Proviron, anastrozole is significantly more effective at controlling estrogen.
Tamoxifen citrate is a non-steroidal anti-estrogenic drug, used widely in clinical medicine. It is specifically a Selective Estrogen-Receptor Modulator (SERM) of the triphenylethylene family, and possesses both estrogen agonist and antagonist properties. As such, it may act as an estrogen in some tissues while blocking the action of estrogen in others. In breast tissue tamoxifen citrate is a strong anti-estrogen, and as a result it is commonly used in the treatment of hormone-responsive breast cancer in women. In some cases it is even utilized as a preventative measure, taken by women with an extremely high familial tendency for breast cancer. In male bodybuilders and athletes, tamoxifen citrate is commonly used (off-label) to counter the side effects caused by elevated estrogens subsequent to the use of certain anabolic/androgenic steroids.
Clomid also known as Clomiphene citrate is an anti-estrogenic drug that is prescribed to women to treat anovulatory infertility (inability to ovulate). In clinical medicine it is specifically referred to as a nonsteroidal ovulatory stimulant. The drug works by interacting with estrogen receptors, often in an antagonistic manner, in various tissues of the body including the hypothalamus, pituitary, ovary, endometrium, vagina, and cervix. One main focus is that the drug will oppose the negative feedback of estrogens on the hypothalamic-pituitary-ovarian axis, enhancing the release of gonadotropins (LH and FSH). This surge in gonadotropins may cause egg release (follicular rupture), ideally leading to conception. Clomid is chemically a synthetic estrogen with both agonist/antagonist properties, and in this regard is very similar in structure and action to Nolvadex. It is believed that both the estrogenic and anti-estrogenic properties of Clomid play a role in its ability to support female fertility.
MENT, short for methylnortestosterone (acetate), is a synthetic anabolic steroid derived from nandrolone. This agent is also called trestolone acetate, although not as commonly. The trivial name methylnortestosterone is vague, and can also be applied to other steroids. In this case the "methyl" in the name, which is commonly associated with C-17 alpha alkylated androgens like methyltestosterone, methandrostenolone, or oxymetholone, is referring to a modification at C-7. This gives Trestolone a considerably different appearance than 17-methylnoretestosterone (Orgasteron). Of most obvious significance is its method of use. Although perhaps possessing a moderate level of oral bioavailability, this nandrolone derivative was not designed for oral ; administration. It is much more effective when administered to the body directly, by injection, implant, or transdermal gel. In character, Trestolone is a strongly anabolic steroid, which is accompanied by moderate androgenic and estrogenic properties.
Halodrol also known as Chlorodehydromethylandrostenediol (CDMA) is an oral anabolic steroid derived from testosterone. It is extremely close in structure to chlorodehydromethyltestosterone (Oral Turinabol), differing only by the substitution of the basic steroid 3-keto group with a 3-hydroxyl. It is essentially a "diol" form of Oral Turinabol, and with this understanding is often described as a "prohormone" or "prosteroid"to this well-known and highly valued anabolic steroid. While some conversion to active chlorodehydromethyltestosterone is assumed, based on its structure it is likely that this conversion is far from complete, and that much of the anabolic and androgenic activity received with use is intrinsic to CDMA. This steroid is non-aromatizable, and exhibits a greater tendency for anabolic as compared to androgenic effect.
Mod GRF 1-29 is a synthetic growth hormone secretagogue from the growth hormone releasing hormone family. These compounds are based on GHRH, a natural peptide hormone that signals the release of GH from the pituitary gland. GHRH is one of two primary positive regulators of GH secretion in humans, acting together with ghrelin. Both hormones are the subjects of extensive drug development. With GHRH, though it can be synthesized as a drug product, it is not really adequate as a therapeutic agent. It is too short acting. Mod GRF 1-29 is potentially more viable. It is a shortened, modified form of GHRH that is more resistant to enzymatic cleavage. It has a longer half-life, and is a more potent agent for increasing serum GH and IGF-1 levels.
Mechano Growth Factor (MGF) is an anabolic hormone from the Growth Hormone family of substances. It was discovered in 1996, when it was found to be a natural "splice variant" of IGF-I (Insulin-like Growth Factor). That is, it is an alternate sequence of IGF-I that is produced locally within the muscles when they are stretched or damaged, as with resistance training. This new form of IGF-I seems to trigger some of the early changes within the cells that support repair and growth, making it of great interest in both medical research and sports doping. The technical label for this variant of IGF-I is human IGF-lEc. However, it is often called MGF because it appears to play a key role in translating mechanical activity into anabolic signaling (growth).
Ipamorelin is a growth hormone secretagogue from the GHRP class (Growth Hormone Releasing Peptides). This is a third generation GHRP. It was developed alongside a series of other modified derivatives of a first generation GHRP. Like other GHRPs, ipamorelin binds and activates growth hormone secretagogue receptor 1a (GHSRIa). This supports the pulsatile release of growth hormone, and in turn potentially IGF-1. As a stimulator of GH release, ipamorelin appears to be moderately potent. It is stronger than GHRP-6, but less effective than GHRP-2. However, it does have unique properties regarding selectivity that make this drug of interest, discussed below. In the fitness community, ipamorelin is most often used for the support of muscle growth and fat loss.
Long(R3)-IGF-l is a synthetic variant of Insulin-Like Growth Factor-1 (IGF-I), a peptide hormone found naturally in the human body. It is a close derivative of this natural protein. The name "Long R3" actually describes how the original IGF-I protein has been modified. It is made by extending the IGF-I protein with a chain of 13 amino acids, and substituting an arginine at the 3rd position. This new synthetic form of IGF-I seems to retain much of the hormone's original biological activity. It binds and activates the IGF-I receptor with similar affinity, and imparts a similar anabolic effect. However, it also differs by displaying a significantly longer half-life, and higher resistance to binding proteins, in comparison. As a result, milligram for milligram, Long(R3)-IGF-l is estimated to be approximately 2.5 to 3 times more potent than natural IGF-I. In the fitness community, this substance is most commonly used to support increases in muscle mass.
HGH Fragment 176-191 is a spliced variant of native human growth hormone. Specifically, it is made of the last 16 amino acids on GH's long 191 amino acid sequence. This fragment seems to retain some (not all) of the biological activity of growth hormone. On the one hand, the compound is no longer able to bind with the cellular GH receptor. As such, it does not elevate serum IGF-1, nor appear to have anabolic effects. On the other, it may still have distinct lipolytic (fat loss) properties. A drug like this could be applicable in situations where fat loss is desired, but GH's wider spectrum of anabolic effects (and potential side effects) is not. In the fitness community, this substance is used exclusively for fat loss.
Hexarelin is a Growth Hormone Releasing Peptide (GHRP). These are a group of synthetic compounds that mimic the effects of ghrelin, a gastrointestinal hormone involved in the regulation of food intake, body composition, and glucose metabolism. Like other GHRPs, hexarelin is an agonist of the growth hormone secretagogue receptor la (GHSRIa). It acts on hypothalamic and pituitary sites to stimulate the release of growth hormone. Hexarelin is a particularly potent member of the GHRP family, capable of substantial increases in serum GH and IGF-1. Compared to its predecessor GHRP-6, hexarelin is significantly more effective at elevating growth hormone, and displays a lower propensity for side effects. This drug is often used in the fitness community for fat loss and muscle gain, or as part of an anti-aging program.
GHRP-6 is a growth hormone secretagogue. It is a first generation Growth Hormone Releasing Peptide (GHRP) to be more specific, one of the earliest drugs of this class to effectively raise serum GH. This agent is an agonist of the growth hormone secretagogue receptor la (GHSRIa). It acts on these receptors in the hypothalamus and pituitary, which stimulates the release of growth hormone. Liver IGF-1 (Insulin-like Growth Factor 1) may also be increased as a result. Provided an ample dose is given, the resulting GH spike from GHRP-6 can reach supraphysiological (higher than normal) levels, although there have been more potent drugs of this class to come after it. This agent is still widely used in the sports community though, most commonly as an appetite stimulant, and to support muscle growth and fat loss alongside other drugs.
GHRP-2 is short for Growth Hormone Releasing Peptide 2, a growth hormone (GH) secretagogue. As its name suggests, this drug stimulates the release of growth hormone. GHRP-2 is presently available as a diagnostic drug for GH deficiency in some markets, where it is usually found under the generic name pralmorelin. GHRP-2 is a fairly potent stimulator of GH release. Though it only increases the body's own synthesis of this hormone, given proper dosing it can produce strong supraphysiological levels of GH on par with exogenous hGH (Human Growth Hormone) administration. It can also be significantly more cost effective in comparison. GHRP-2 is most commonly used in the fitness community for the purposes of fat loss and muscle gain, as well as an anti-aging therapy.
CJC-1295 is a synthetic growth hormone secretagogue. It specifically belongs to the growth hormone releasing hormone (GHRH) family of drugs. These compounds all mimic the effects of endogenous GHRH, a 44-amino acid hypothalamic peptide hormone that stimulates the release of growth hormone from the pituitary gland. CJC-1295 is actually a very long acting GHRH analog. Whereas native GHRH has a half-life measured in minutes, which reduces its practicality as a therapeutic agent, CJC-1295 is capable of sustained increases in growth hormone and IGF-1 with as little as once per week administration. This drug is used in the fitness community for the support of muscle growth and fat loss, as well as its potential anti-aging properties.
YK11 is a steroidal Selective Androgen Receptor Modulator (SARM). Where as most SARMs are removed from traditional AAS structurally, YK11 is built on the same common steroid backbone. It is still quite unique, however, and does not closely resemble any common anabolic steroid. This unusual structure may afford it some level of selectivity in action, similarto other SARMs. YK11 is described as a partial AR agonist. It appears to activate the androgen receptor, though in some tissues may not result in full transcribing activity. As such, it could have a reduced level of relative androgenicity. Admittedly though, the classification of YK11 as a SARM is a tenuous one.
RAD140 is non-steroidal Selective Androgen Receptor Modulator (SARM). Drugs of this class mimic many of the beneficial actions of anabolic steroids, but are often quite removed from these drugs structurally. This often allows for much higher anabolic-androgen separation, and differing side effect potential. The objective is typically to maximize stimulation of bone and muscle anabolic effects, and minimize other androgenic spillover, particularly in the prostate. This drug is commonly used in the fitness community, as a muscle-building alternative to anabolic steroids.
Ostarine is a second generation Selective Androgen Receptor Modulator (SARM). Though non-steroidal in structure, this drug is closely related to anabolic/androgenic steroids in its activity. Ostarine selectively activates the cellular androgen receptor (AR) in certain tissues, most notably skeletal muscle and bone. Here it supports constructive metabolism (anabolism). It is also believed to support satellite cell cycle activation, possibly outside of traditional AR binding. Ostarine is far less active in "androgenic" tissues such as the prostate and sex organs, however, which gives it a distinct separation of anabolic and androgenic effect. This drug is widely used in the sports community for muscle gain and fat loss, typically as an alternative to anabolic steroids.
Ligandrol is a second generation Selective Androgen Receptor Modulator (SARM). Though commonly nonsteroidal in structure, drugs of this class are closely related to anabolic/androgenic steroids in action. It binds to the same androgen receptor, and exerts similar anabolic effects. However, SARMs tend to do so with a great deal more tissue selectivity. As such, we can notice much greater separation of anabolic and androgenic effect. Ligandrol is reflective of this tendency. It is a strong agonist of the AR in skeletal muscle and bone, and only a weak partial agonist in the prostate. Like many SARMs, it may hold promise as a therapeutic agent, offering similar anabolic benefits to traditional AAS, but with fewer side effects.
Ibutamoren, also commonly known by its research designation MK-677, is a growth hormone secretagogue. More specifically, it belongs to the GHRP (Growth Hormone Releasing Peptides) class. These drugs all mimic the activity of ghrelin on the growth hormone secretagogue receptor la (GHSRIa), which stimulates the pulsatile secretion of this hormone from the pituitary. Ibutamoren is considered a third generation GHRP, mostly for its refined oral bioavailability. In human studies, it has been shown to significantly elevate serum GH and IGF-1 levels in both the young and elderly, increase fat-free mass and energy expenditure, improve sleep quality, and reduce diet-induced catabolism. In the fitness community, this drug is most commonly used for muscle gain and fat loss, as well as an appetite stimulant.
Endurobol (also known as GW501516 or Cardarine) is a PPARD (Peroxisome Proliferator-Activated Receptor Delta) receptor agonist. This receptor plays an important role in human metabolism, as it is involved in the regulation of genes that help manage the transport and oxidation of fatty acids. PPARD agonists are of great interest in medical research at present, as they hold the potential to influence areas such as insulin sensitivity, glucose tolerance, and lipid balance. Further, they may offer therapeutic benefit with conditions such as obesity, type 2 diabetes, and high cholesterol. Endurobol is a research drug, once under development for improving HDL cholesterol in patients with dyslipidemia.
Andarine is a second generation Selective Androgen Receptor Modulator (SARM). SARMs are all closely related to anabolic steroids in activity.They bind the same cellular androgen receptor (AR), and impart similar anabolic effects. However, like andarine, most are non-steroidal in structure. They are also highly selective in their receptor interactions (hence the name). These drugs are often full agonists of the Aft in "anabolic" tissues such as bone and skeletal muscle, but only partial agonists in "androgenic" areas like the prostate and sex organs. As such, they should have a significantly higher separation of anabolic and androgenic effect. There is also no conversion to estrogen, and likely minimal spillover with other hormones.
Turinabol also known as Chlorodehydromethyltestosterone is a potent derivative of Dianabol. This oral steroid is structurally a cross between methandrostenolone and clostebol (4-chlorotestosterone), having the same base structure as Dianabol with the added 4-chloro alteration of clostebol. This alteration makes Turinabol a milder cousin of Dianabol, the new steroid displaying no estrogenic and a much less androgenic activity in comparison to its more famous counterpart. The anabolic activity of Turinabol is somewhat lower than that of Dianabol as well, but it does maintain a much more favorable balance of anabolic to androgenic effect. This means that at any given level of musclebuilding activity, Turinabol will be less likely to produce androgenic side effects.
Active substance of Salbutamol is Albuterol sulfate. Albuterol sulfate is a selective beta-2 adrenergic agonist, very similar in structure and action to clenbuterol. Unlike clenbuterol, however, albuterol is readily available as a prescription drug in the United States. It is also sold as salbutamol in a number of other countries, which is another generic name for the drug. Albuterol is most commonly found in the form of a rescue inhaler, which is designed to disperse a measured amount of the drug immediately and directly to the bronchial tubes in times of crisis (asthma attack). This form provides the least amount of systemic drug activity possible, which is great for minimizing unwanted cardiovascular side effects. Albuterol oral tablets are also available, however, and provide a systemic dose of the drug. These are the subject of interest in the bodybuilding and athletic communities, and they can provide significant beta-2 stimulation and measurable fat loss throughout the body given the right conditions. Note that a more comprehensive discussion of the benefits, activities, and side effects of beta-2 agonist drugs can be found under the clenbuterol drug profile.
Proviron is Schering’s (now Bayer’s) brand name for the oral androgen mesterolone (1- methyl dihydrotestosterone). Similar to dihydrotestosterone, mesterolone is a strong androgen with only a weak level of anabolic activity. This is due to the fact that like dihydrotestosterone, mesterolone is rapidly reduced to inactive diol metabolites in muscle tissue where concentrations of the 3-hydroxysteroid dehydrogenase enzyme are high. The belief that the weak anabolic nature of this compound indicates a tendency to block the androgen receptor in muscle tissue, thereby reducing the gains of other more potent musclebuilding steroids, should likewise not be taken seriously. In fact, due to its extremely high affinity for plasma binding proteins such as SHBG, mesterolone may actually work to potentate the activity of other steroids by displacing a higher percentage into a free, unbound state. Among athletes, mesterolone is primarily used to increase androgen levels when dieting or preparing for a contest, and as an anti-estrogen due to its intrinsic ability to antagonize the aromatase enzyme.
Oxymetholone is a potent oral anabolic steroid derived from dihydrotestosterone. More specifically, it is a close cousin of methyldihydrotestosterone (mestanolone), differing only by the addition of a 2-hydroxymethylene group. This creates a steroid with considerably different activity than mestanolone, however, such that it is very difficult to draw comparisons between the two. For starters, oxymetholone is a very potent anabolic hormone. Dihydrotestosterone and mestanolone are both very weak in this regard, owing to the fact that these molecules are not very stable in the high enzyme (3-alpha hydroxysteroid dehydrogenase) environment of muscle tissue. Oxymetholone remains highly active here instead, as is reported in standard animal assay tests demonstrating a significantly higher anabolic activity than testosterone or methyltestosterone. Such assays suggest the androgenicity of oxymetholone is also very low (1/4th to 1/7th its anabolic activity), although real world results in humans suggest it is decidedly higher than that. Oxymetholone is considered by many to be the most powerful steroid commercially available. A steroid novice experimenting with this agent is likely to gain 20 to 30 pounds of massive bulk, and it can often be accomplished within 6 weeks of use. This steroid produces a lot of water retention, so a good portion of this gain is going to be water weight. This is often of little consequence to the user, who may be feeling very big and strong while taking oxymetholone. Although the smooth look that results from water retention is often not attractive, it can aid quite a bit to the level of size and strength gained. The muscle is fuller, will contract better, and is provided a level of protection in the form of extra water held into and around connective tissues. This will allow for more elasticity, and will hopefully decrease the chance for injury when lifting heavy. It should be noted, however, that a very rapid gain in mass might also place too much stress on your connective tissues. The tearing of pectoral and biceps tissue is commonly associated with heavy lifting while massing up on steroids, and oxymetholone is a common offender. There can be such a thing as gaining too fast.
Oxandrolone is an oral anabolic steroid derived from dihydrotestosterone. It was designed to have a very strong separation of anabolic and androgenic effect, and no significant estrogenic or progestational activity. Oxandrolone is noted for being quite mild as far as oral steroids are concerned, well tailored for the promotion of strength and quality muscle tissue gains without significant side effects. Milligram for milligram it displays as much as six times the anabolic activity of testosterone in assays, with significantly less androgenicity. This drug is a favorite of dieting bodybuilders and competitive athletes in speed/anaerobic performance sports, where its tendency for pure tissue gain (without fat or water retention) fits well with the desired goals.
Methandienone is also referred to as methandrostenolone in many countries. Methandrostenolone is a derivative of testosterone, modified so that the hormone’s androgenic (masculinizing) properties are reduced and its anabolic (tissue building) properties preserved. Having a lower level of relative androgenicity than testosterone, methandrostenolone is classified as an “anabolic” steroid, although quite a distinct androgenic side is still present. This drug was designed, and is principally sold, as an oral medication, although it can also be found in a number of injectable veterinary solutions. Methandienone is today, and has historically been, the most commonly used oral anabolic/androgenic steroid for physique and performance-enhancing purposes.
Methyltestosterone is an orally available form of the primary male androgen testosterone. Looking at the structure of this steroid, we see it is basically just testosterone with an added methyl group at the c-17 alpha position (a c-17 alpha alkylated substance), which allows for oral administration. The resultant compound “methylated-testosterone” was among the first functional oral steroids to be produced. This field of research has consequently improved greatly over the years, and today methyltestosterone is quite crude in comparison to many of the other orals that were subsequently developed. The action of this steroid is moderately anabolic and androgenic, with high estrogenic activity due to its aromatization to 17-alpha methyl estradiol. This generally makes methyltestosterone too troublesome (in terms of estrogenic side effects) to use for muscle-building purposes.
Methyldrostanolone, also known as methasteron, is a potent oral anabolic steroid that was never sold as a prescription drug. In structure, this steroid is a close derivative of drostanolone (Masteron). The only difference in this case is the addition of a c-17 alpha methyl group, a modification that gives this steroid high oral bioavailability. The two agents remain very comparable, however. Both methyldrostanolone and drostanolone are non-aromatizable, so there is no difference in the estrogenicity of these two steroids, and both steroids retain favorable anabolic to androgenic ratios. Lab assays do put Methyldrostanolone ahead here, however, showing it to possess 4 times the anabolic potency of oral methyltestosterone while displaying only 20% of the androgenicity (a 20:1 ratio, compared to 3:1). The exact real-world relevance of these figures remains to be seen, however. Methyldrostanolone is favored by athletes for its moderate anabolic properties, which are usually accompanied by fat loss and minimal androgenic side effects.
Halotestin is an oral anabolic steroid derived from testosterone. More specifically, it is amethyltestosterone derivative, differing by the addition of 11-beta-hydroxy and 9-alphafluoro groups. The result is a potent orally active non-aromatizable steroid that exhibits extremely strong androgenic properties. Halotestin is considerably more androgenic than testosterone, while at the same time the anabolic effects of this agent are considered to be moderate in comparison. This makes Halotestin a great strength drug, but not the most ideal agent for gaining muscle mass. The predominant effects seen when taking Halotestin are increased strength, increased muscle density, and increased definition, with only modest size increases.
Clenbuterol hydrochloride is an anti-asthma medication that belongs to a broad group of drugs knows as sympathomimetics. These drugs affect that sympathetic nervous system in a wide number of ways, largely mediated by the distribution of adrenoceptors. There are actually nine different types of these receptors in the body, which are classified as either alpha or beta and further subcategorized by type number. Depending on the specific affinities of these agents for the various receptors, they can potentially be used in the treatment of conditions such as asthma, hypertension, cardiovascular shock, arrhythmias, migraine headaches and anaphylactic shock. The text Goodman and Gillman’s The Pharmacological Basis of Therapeutics 9th edition does a good job of describing the diverse nature in which these drugs affect the body.
Sustanon 250 is an oil-based injectable testosterone blend that contains four different testosterone esters: testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60 mg); and testosterone decanoate (100 mg). Sustanon is designed to provide a fast yet extended release of testosterone, usually requiring injections once every 3 to 4 weeks in a clinical setting. This is an improvement from standard testosterones such as cypionate or enanthate, which provide a shorter duration of activity. As with all testosterone products, Sustanon 250 is a very strong anabolic drug with pronounced androgenic activity. It is most commonly used in bulking cycles, providing exceptional gains in strength and muscle mass. A shorter-acting version of Sustanon, called Sustanon 100, is also made in certain areas.
Testosterone enanthate is a slow-acting injectable form of the androgen testosterone. Following deep intramuscular injection, the drug is designed to provide a sustained release of testosterone into the bloodstream for approximately 2 to 3 weeks. In order to maintain normal physiological levels of testosterone during androgen replacement therapies, injections of testosterone enanthate are usually required at least every two weeks, although more meticulous physicians will administer the drug weekly. As with all testosterone injectables, testosterone enanthate is highly favored by athletes for its ability to promote strong increases in muscle mass and strength.
Testosterone cypionate is a slow-acting injectable ester of the primary male androgen testosterone. Testosterone is also the principle anabolic hormone in men, and is the basis of comparison by which all other anabolic/androgenic steroids are judged. As with all testosterone injectables, testosterone cypionate is highly favored by athletes for its ability to promote strong increases in muscle mass and strength. It is interesting to note that while a large number of other steroidal compounds have been made available since testosterone injectables, they are still considered to be the dominant bulking agents among bodybuilders. There is little argument that these are among the most powerful mass drugs available, testosterone cypionate included.
