About S-23

S-23 is an orally bioavailable, non steroidal selective androgen receptor modulator (SARM) that has been proven to increase lean muscle and bone tissue while being tissue selective (unlike traditional steroids).

Studies and user reports suggest that S-23 is the closest SARM to steroids, with a few key differences, such as decreased prostate size. Other user reports suggest that S-23 is a much more powerful version of S4 Andarine) and the benefits of this SARM falls in the category of hardening muscle and creating a grainier aesthetic look.

S-23 effects

As a member of the SARM category, S-23 works to selectively target and produce anabolic results in muscle and bone tissue without some of the limitations and side effects of traditional steroids.

Many users and studies suggest that S-23 is one of the most powerful SARMs on the market. We’ve listed the primary benefits you can expect when taking S-23. The number one benefit of supplementing with S-23 is its ability to increase lean body mass. The second core benefit is the proven ability to retain gains after completing a cycle.

S-23 can increase strength and stamina during high-intensity workouts. Want to work out longer, harder and get better results every time you hit the gym? Users report enhanced speed, stamina and endurance during workouts when supplementing with S-23. Additionally, thanks to its ability to increase lean muscle tissue and decrease fat, high-intensity workouts and interval training can be optimized every time. One thing to note, however, is a user-reported side effect of increased anger whilst supplementing with S-23, which may be a factor in increased effort and intensity during a workout.

The study showed that rats treated with S23 increased lean muscle mass and bone mineral density whilst simultaneously reducing fat loss percentage. Interestingly, this study shows that there is an inverse relationship between a higher dose of S-23 and a decrease in body fat. This suggests that a higher dose of S-23 results increased fat loss.

Water retention isn’t all bad. Some users suggest that water retention and bloating experienced during bulking periods can help to lubricate and protect joints. But S-23 has been shown to offer minimal (if any) water retention and bloating, which means that all gains during a cycle will be retained. The fact that S23 does not cause water retention makes it ideal for cutting periods.

Some users suggest using S-23 to maintain and build lean muscle whilst cutting, as this SARM tends to develop dry, grainy-looking muscles that are otherwise unattainable without traditional steroids. Many body builders find S-23 ideal in the lead up to competitions in order to create the level of muscular detail that wins competitions.

S-23 administration

User reports suggest that 20mg-30mg split into three doses throughout the day provides the best results. This would look like 3 doses of 10mg spread throughout the day.

Current research indicates that it is tolerated for use up to 8 weeks, with users suggesting incorporating it into the last 8 weeks of a 12-week cycle.

As a contraceptive, studies suggest a dosage of 50mg may be effective, but as it is still in testing stages, we do not advise using S-23 as a male contraceptive. 

S-23 side effects

Below are some of the typical side effects associated with taking the S-23 SARM, each one in further detail…

Testosterone shutdown
S-23 is the most potent SARM to date and has been suggested to be as close to traditional steroids as possible. With this in mind, the side effects of S-23 are dissimilar to other SARMs, in that it does actually show an effect on testosterone levels in the form of complete down. Users report minimizing or even eliminating this side effect by supporting their supplementation of S-23 with Testosterone Replacement Therapy (TRT).

These side effects were completely reversed in studies upon cessation of S-23 and the completion of a full PCT.

Increased aggression
Some users report increased aggression when supplementing with S-23, which could be a deterrent to some users with known anger issues.

Testicle and prostate shrinking
Temporary shrinkage of the testicles has been noted by some users, and the primary study on S-23 shows prostate shrinkage. However, it’s worth noting that even with its similarities to steroids, the decrease in prostate size is unusual as steroids normally cause an increase, which can cause issues. Users note that testicle shrinkage was reversible once supplementation was stopped.

Darker urine
Some users report darker-than-usual urine while cycling S-23. This stopped when the cycle was complete.
