S-4 (Andarine) was originally developed to be used as male contraceptive and showed promising results in decreasing spermatogenesis and huge boosts in male libido. However, researchers soon discovered that Andarine increased the production of muscle mass and calcium for bone density. Continued studies resulted in astonishing outcomes for the bodybuilding uses of S-4. 

S-4 is a SARM, a Selective Androgen Receptor Module, meaning it attaches itself to an Androgen receptor and forces it to produce genes that exclusively benefit muscle and bone growth. 

A few benefits of S-4 are:

  • Effectively assists in the loss of Body Fat and subsequently, body weight
  • It does not have any steroidal effects
  • Huge Increase in muscle mass and strength
  • Increases the strength of your bones
  • Under the recommended dosage, it is a pretty safe product to use
  • Promotes good sexual stamina
  • Can be stacked with other SARMs products.
