S4 (A'ndarine) or Acetamidoxolutamide, is a SA (Androgen Receptor). S4 is said to be the most potent SA which helps sustain lean muscle mass while stimulating fat elimination at the same time.

S4 is a form of SA that attaches to the androgen receptor (AR) the same with regular androgens, the only variation is that S4 generates selective anabolic activity. S4 is a SA with utmost androgenic effects as it around 33% of the strength of test when attaching to AR.

Compared to steroids raw powder and prohormones, A'ndarine does not have androgenic activity in non-skeletal muscle tissues .

S4 is a SA with maximum potential with a disintegration process of just 4 hours. It can decrease the size of the prostate if taken as recommended. It is administered orally.

It's shown to be beneficial for muscle degeneration, osteoporosis and benign prostatic hypertrophy (with bicalutamide - a non-steroidal androgen antagonist) treatment. Aside from preserving lean body mass, S4 can also help improve it.

Aside from its muscle building advantages, S4 won't cause liver damage, can prevent gynecomastia (enlarged breasts in men) and can help boost your overall health .
