Andarine
Andarine (developmental code names GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy,[1] using the nonsteroidal antiandrogen bicalutamide as a lead compound.[2]

Andarine is an orally active partial agonist of the androgen receptor (AR). It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or antiandrogenic side effects.[3] This suggests that it is able to competitively block binding of dihydrotestosterone to its receptor targets in the prostate gland, but its partial agonist actions at the AR prevent the side effects associated with the antiandrogens traditionally used for treatment of BPH.[4]
