S4 Andarine Powder

Andarine, also known as S-4 [Andarine, S3-(4-acetylamino-phenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide], is a selective androgen receptor modulator (SARM). It was developed by GTx Inc. with the intention of treating conditions such as muscle wasting, osteoporosis, and benign prostatic hypertrophy. However, it has also gained popularity in the fitness and bodybuilding communities for its potential to enhance muscle mass and strength. Selective androgen receptor modulators (SARMs) are a relatively new class of non-steroidal compounds that possess potent ana bolic activity. They were developed following the identification of androgen receptor antagonists such as bicalutamine in 1998, as an alternative to anabolic steroids for treating a wide range of clinical conditions including cancer cachexia, muscle wasting, osteoporosis, androgen deficiency, and prostate cancer2.
