Benefits and Description

S4, also known as Andarine, Andarin, S-40503, or GTx-007, is a SARM that selectively binds to androgen receptors in skeletal muscle tissue. There is little danger of nonskeletal muscle tissues experiencing androgen activity.  Additionally, research has shown it does not cause aromatization (conversion of testosterone into estrogen), liver strain, or severe HPTA (hypothalamic pituitary testicular axis) suppression. Aside from building lean body mass, andarine is also used for benign prostatic hypertrophy, muscle wasting, and osteoporosis.

Concentration

50mg/ml.

Half Life

4 – 6 hours.

Side Effects

High dosages may result in short-term changes in vision due to a metabolite of S4 binding to vision receptors. Changes go away after the SARM is no longer in the system.

Some users have shown very slight suppression when using S4. A short, mini post cycle therapy regiment is required; the recovery time is only 2-3 weeks after completion.
