What is S-4?
As a research chemical, S-4 belongs to a class of chemicals known as SARMS or selective androgen receptor modulators. Like typical androgens, SARMS bind to the androgen receptor however SARMS create selective anabolic activity. Compared to testosterone and other anabolic steroids and pro hormones, the advantage of SARMS such as S-4 is that they do not have androgenic activity in non-skeletal-muscle tissues. S4 was designed for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound. As an orally active partial agonist for androgen receptors, S-4 is effective in not only maintaining lean body mass but actually increasing it.Usage
Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound. Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects. This suggests that it is able to competitively block binding of dihydrotestosterone to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH. Andarine S4 is a SARM that was developed for treatment of muscle wasting, osteoporosis and benign prostatic hypertrophy. S4 is effective in not only maintaining lean body mass, but increasing it while reducing body fat.Hot sell products

Losing Bodyfat (Cutting)
Certain steroids are considered "cutting" steroids such as Winstrol and Anavar. These steroids don't offer too much in large gains in muscle mass but are very effective in leaning out the body. The SARM S-4 has very similar properties.As S-4 shows this binding affinity to the AR, it demonstrates the similar fat burning effects. S-4 also shows a decrease in LPL (lipoprotein lipase) which is an enzyme that causes lipid accumulation. S-4 also fits into a cutting protocol for the concurrent reduction in body fat with maintenance of muscle mass in a hypocaloric environment. As S4 has both anabolic and androgenic effects in muscle tissue, it will not only help with fat loss, but maintain and even increase muscle mass when cutting.S-4 causes increases in vascularity and promote a very nice, "quality", hard look to the users muscles, with little or no water retention.
