Methenolone Enanthate (CAS 303-42-4) Androgenic Anabolic Steroid API

Methenolone Enanthate (CAS 303-42-4) is a high-purity androgenic anabolic steroid API with a favorable anabolic-androgenic ratio. It selectively activates androgen receptors to enhance protein synthesis and nitrogen retention, promoting lean muscle mass growth while minimizing androgenic side effects. It is mainly used for the research of muscle wasting disorders, osteoporosis, and hormone replacement therapy. Its refined crystalline form ensures consistent bioactivity and low impurity profiles, making it a reliable active ingredient for endocrinology and sports medicine pharmaceutical R&D.

Tailored for pharmaceutical manufacturers and endocrinology research institutions, this product adheres to strict global steroidal quality standards. It addresses the core demand for low-androgenic anabolic raw materials, supporting the development of formulations for muscle atrophy and osteoporosis research. Its stable chemical structure guarantees extended shelf life under proper storage, facilitating flexible formulation design for injectable preparations and clinical trial applications.
