S4 is a SARM that was discovered by GTX labs as a possible therapeutic remedy for a host of conditions including muscle loss. However, it is the effectiveness of the drug in the treatment of benign prostatic hypertrophy that bought it into the spotlight.

Like most other SARMS, S4 is orally bioavailable and an active partial agonist for selected androgen receptors and helps in boosting lean muscle mass and in faster oxidation of stored fat.

Benefits have been shown to include:

  • increased muscular fullness and hardness, as well as better pumps

  • by working through the androgen receptor, it is able to produce effects as powerful as testosterone

  • increase lean muscle mass

  • increased levels of fat loss

  • no side effects on reproductive organs

  • enhanced recovery

  • can be stacked with other sarms for maximum effectiveness

  • potent even at low doses
