WHAT IS IT?
S-23 is a selective androgen receptor modulator (SARM) and has been studied and proven to increase muscle mass, reduce fat mass, and has a very high binding affinity to the androgen receptors. It is non-steroidal and has tissue-selective anabolic effects in muscle and bone, while sparing other androgenic effects that come from anabolic androgenic steroids (AAS). It also has been shown to decrease prostate size in studies, which is the opposite of a very common negative side effect of anabolic steroids (enlargement of the prostate).
WHAT ARE THE RESULTS?
Great lean mass builder. Notable increases in strength and endurance. Enhanced levels of fat oxidization. Can completely off-set catabolism in a calorie deficit. Body fat melts off much easier. Greatly enhanced levels of muscle hardness, dryness, and vascularity. Zero water retention.
Basically, S-23 is a jacked-up version of S4, exerting all of the same benefits to an even greater extent, without the vision side effects. S-23 essentially falls into the extreme “hardener” category. Another way to describe this kind of compound is it can make you look quite a bit leaner than you are. These compounds have a blatant cosmetic effect on the muscle that no other kind of compound can achieve.
S-23 will not only suppress you more than all the other “mainstream” SARMs would, but it could completely shut you down. Now, this isn’t something to freak out about necessarily, as being “shutdown” doesn’t mean your endocrine system has crashed and will never recover, it just means you probably need a more intensive PCT.
Increased aggression comparable to that of RAD140. If you are a hot head or already have a bad temper, I suggest avoiding S-23 entirely. Testosterone suppression to a large extent. Temporary testicle shrinkage (reversible during PCT). Decrease in prostate size (actually a benefit as anabolic steroids are notorious for increasing prostate size).
USE OF A PCT IS 100% NECESSARY
