SARMs S4 Andarine 50mg/ml @ 30ml

S4 (Andarine) – Selective SARM for Muscle & Bone Research

S4 (Andarine) is a selective androgen receptor modulator (SARM) developed for tissue‑specific anabolic activity. It exhibits high binding affinity to androgen receptors in muscle and bone, promoting lean mass preservation and bone density, while showing reduced stimulation in prostate and other androgen‑sensitive tissues. Preclinical research has investigated S4 for conditions such as muscle wasting, osteoporosis, and benign prostatic hyperplasia (BPH) . Unlike many other SARMs, Andarine is known for its unique ocular side effects in research models, including a yellow‑tinted vision response.

Key Research Applications:

• Muscle preservation and hypertrophy studies

• Bone density and fracture healing models

• Androgen receptor selectivity research
