product description
1)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.
2)Compared to t and other an st 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.
How S4 Works |
A SARM such as S-4 is a good example. S-4 attaches to the AR and sticks to it; each time the AR interacts with test, S-4 forces it to produce genes that exclusively benefit muscle and bone growth. In other words, S4 is a form of SARM that attaches to the androgen receptor (AR) the same with regular androgens, the only variation is that S4 generates selective anabolic activity. |
