S23 belongs to a group of drugs called SARM (Selective Androgen Receptor Modulator). SARM works like Testosterone by mimicking the anabolic properties. The difference between Androgenic Anabolic Steroids and SARM is that it does not produce highly pronounced androgenic results, in other words the less severe androgenic results. It is called selective androgen receptor modulator because anabolic steroids bind androgen receptors throughout the body. In case of SARM, binding of androgen receptors happens only in selective tissues. SARM category of drugs are used therapeutically to achieve the results of anabolic steroids in specific areas of the body and thereby minimize the side effects and the negative risks. SARMs are used for treating ailments that lead to muscle wasting and some of these ailments include end-stage renal disease, cancer, heart failure, end-stage liver disease, osteoporosis, HIV and chronic obstructive pulmonary disease.
It is comparable to steroids and is the only SARM, alongside with YK11, where PCT is absolutely necessary, no matter what dosage you imbue.
Bodybuilders usually take between 10 to 30 mgs of S23 per day, especially considering the side effects of the compound, an example being the heavy Testosterone suppression experienced. This sarm requires users to run a pct consisting of Clomd and Nolvadex.
SARM S23 shares all the above qualities. The proponents of S23 claim that it is one of the most powerful SARMs available in the market today. Bodybuilders claim that S23 helps them achieve the benefits of steroids but without having to suffer the negative side effects of the steroids. S23 is very effective in building lean muscle mass. It also improves the skeletal mass. These two important benefits make bodybuilders opt for S23 over steroids as they are free from the steroid based side effects. S23 also supports speedy fat burning.
