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. Thanks to its side effect friendly nature, ease of use and affordable price, GHRP-2 is one of the more appealing growth hormones on the market. It is a solid addition to any performance-based stack, but in anti-aging circles this is where you’ll find it’s most beneficial.
10mg GHRP-2 (VIAL)
This drug belongs to the Growth Hormone Releasing Peptides (GHRP) class. These are all synthetic compounds that mimic, to some degree, the effects of ghrelin, an endogenous gastrointestinal peptide hormone. Ghrelin is secreted by the stomach at times of fasting (when unfed). This hormone stimulates receptors in various tissues including the hypothalamus, pituitary, and other regions of the brain, the sympathetic nervous system, the stomach, heart, pancreas, liver, and intestines, and even adipose tissue. Ghrelin is most generally involved in the regulation of food intake, body composition, and glucose metabolism. Among other things, it has been shown to stimulate appetite, influence taste, modulate sleep, stimulate gastric motility, emptying, and acid secretion, promote lean body mass retention, improve cardiac output, reduce inflammation, increase plasma glucose levels, and alter peripheral insulin sensitivity.
Ghrelin is an agonist of the growth hormone secretagogue receptor la (GHSRIa). As such, it has been shown to increase acute GH release and 24-hour pulsatile GH secretion from the anterior pituitary. This, in turn, may also support increases in IGF-1 (Insulin-like Growth Factor 1) production. Several other pituitary-secreted or linked hormones may also be stimulated in the elevated presence of ghrelin, including ACTH (adrenocorticotropic hormone), cortisol, and prolactin. On the other hand, ghrelin may serve to lower insulin secretion and suppress LH (luteinizing hormone). Of course, depending on the therapeutic need, not all of this is desired. As a drug, ghrelin could produce spillover effects in other areas. This spillover tendency is reduced in many of the GHRP analogs, however, which are often more selective in their actions.
GHRP-2 does have a tendency to moderately increase ACTH, cortisol, and prolactin levels. These would be regarded as spillover effects on other systems. However, it does still seem to display some selectivity. It is estimated to be between 2-3 times more potent at stimulating GH release than its most direct predecessor, GHRP-6. At the same time, the appetite-stimulating properties are markedly lower. Some increase in appetite is still reported by a majority of users, however. This just occurs less commonly, and tends to be less profound and shorter lasting when it does. GHRP-2 is also regarded as less effective for injury healing in comparison. This might be linked to a lower level of spillover effect toward cortisol.
GHRP-2 (Growth Hormone Releasing Peptide 2) is a growth hormone similar to GHRP-6. In many circles, it is considered the better choice between it and GHRP-6. It is not a hormone that is often used alone but is almost always used with a Growth Hormone Releasing Hormone (GHRH) such as MGF or CJC-1295 DAC.
GHRP-2 aids in the promotion of natural growth hormone production in the body, which carries with it numerous performance as well as health benefits for the user.
Off-season athletes using GHRP-2 will find growth enhanced when used with other performance-based items, and they will find such items are more effective with the presence of elevated levels of growth hormone in the body. Equally important, the individual should be able to maintain a lower level of body fat that often increases during off-season periods of growth due to the necessary caloric surplus needed for muscular growth.
During a cutting phase is when the effects of GHRP-2 may be most beneficial due to increased levels of growth hormone aiding tremendously with fat loss. Individuals with elevated levels of growth hormone in the body provided naturally or otherwise will experience greater levels of fat loss.
Those who possess higher levels of growth hormone will find the following:
- more powerful metabolism
- increased recovery (post training or any physical activity)
- improved sleep
- stronger immune system
- healthier skin
- stronger bones & joints
- increased IGF-1 (aides in recovery and affects nearly all cells of the human body)
GHRP-2 will come in dry powder form and will be reconstituted with bacteriostatic water. The compound may be injected subcutaneously (under the skin) or intramuscularly (into the muscle) depending on individual preference. Once reconstituted, GHRP-2 must be kept refrigerated.
GHRP-2 can be used indefinitely and will normally be used continuously in anti-aging plans that call for it with a growth hormone releasing hormone (GHRH). Dosing can range dramatically depending on need with 100-300mcg per day being commonplace. If used with a growth hormone releasing hormone (GHRH), which is recommended, the dose may often be towards the lower end of the scale.
For optimal results, the user will find two injections per day on an empty stomach to be best. If done subcutaneously this should prove to be the easiest method as it will be the least intrusive.
When used for physique- or performance-enhancing purposes, GHRP-2 is usually administered at a dosage of 0.1 to 0.3 mg (100-300 meg) per injection. This may be given 1 -3 times daily. If single episode dosing is preferred, this is taken before sleep. Day dose(s) are taken on an empty stomach, 30-60 minutes before feeding. This is to preserve optimal GH release, as elevated plasma fatty acids and/or glucose may blunt the GH elevating effects of GHRP-2. Total daily dosage generally does not exceed 900 meg.
It is common to taper up the dosage, beginning with 100 meg per injection. The dosage may then be increased in increments of 50 meg every 3-7 days, until a stable dosage is reached.
Cycles of GHRP-2 usually last 3-4 months in length, though programs of 6 months or longer are not uncommon. Although desensitization to GHRPs may occur over time, this drug appears to maintain an acceptable level of effectiveness during longer cycles.
GHRP-2 side effects
Common side effects to GHRP-2 therapy include flushing, sweating, sleepiness, increased Gl motility, and increased appetite. Also frequently reported are adverse effects typically associated with other types of growth hormone therapy, such as water retention (edema), joint pain (arthralgias), carpal tunnel syndrome, and numbness or tingling in the extremities. Note that the incidence of side effects tends to be lower with GHRP therapy as compared to traditional hGH. This is because GH/IGF-1 release is subject to endogenous synthesis, and as such the drug is less amenable to overdosing.
The subcutaneous administration of this drug may cause redness, itching, pain, or lumps at the site of injection. Injection site redness and discomfort is sometimes reported with intramuscular injection as well.
GHRP-2 may reduce insulin sensitivity and raise blood sugar levels. This may occur in individuals without preexisting diabetes or impaired glucose tolerance.
Estrogenic side effects of GHRP-2 should not exist as the peptide does not cause any aromatization. However, gynecomastia in sensitive individuals is still possible.
Hair loss and acne are not possible, nor are virilization symptoms in women.
There are no negative cardiovascular side effects associated with GHRP-2. Many users may find their cardiovascular health improves with elevated levels of growth hormone. GHRP-2 will not suppress natural testosterone production.
GHRP-2 is not toxic to the liver and will produce no liver damage.
The most common side effects of GHRP-2 will be an irritated injection site. This will normally remedy itself by finding new areas of the body to administer the peptide. Some users may also experience swollen ankles or wrist as well as carpel tunnel like symptoms when use first begins.
Some users may also find issues with blood sugar control and may need to adjust their diets accordingly. Such blood sugar issues may produce mild to severe headaches.
Elevated levels of cortisol are also possible but are normally only associated with very high doses, such doses should be avoided.
