Technical Specifications & Chemical Profile

Research Applications & Storage Protocols

Androgen Receptor Partial Agonism & Tissue-Selective Anabolic Profiling

Andarine (S-4, GTx-007) functions as an orally active partial agonist of the androgen receptor with high binding affinity (Ki = 4 nM), demonstrating remarkable tissue selectivity in vivo pharmacological activity. In castrated male rat models, S-4 treatment fully restored soleus muscle strength without altering muscle contraction kinetics, demonstrating potent anabolic effects on skeletal muscle. The compound exhibits tissue-selective anabolic activity, producing strong effects on muscle preservation and bone strength enhancement while showing reduced activity in reproductive-associated organs such as prostate and seminal vesicles, confirming its SARM profile with a better safety profile than traditional androgens. Originally developed by GTX, Inc. for treating muscle wasting diseases, osteoporosis, and benign prostatic hyperplasia (BPH), Andarine was researched using the nonsteroidal antiandrogen bicalutamide as a lead compound, but development was discontinued in favor of the structurally related and improved compound enobosarm (ostarine; GTx-024; S-22). Andarine has been shown to improve lean muscle mass and enhance bone strength while selectively targeting muscle and bone tissues without affecting other parts of the body like traditional anabolic steroids, making it valuable for studies involving muscle preservation and skeletal health. This tissue-selective mechanism positions Andarine solution as a critical tool compound for investigating sarcopenia mechanisms, osteoporosis treatment pathways, muscle wasting disease research, BPH models, and age-related muscle loss in preclinical studies, offering potential therapeutic benefits without traditional androgen side effects.
