Chlorodehydromethyltestosterone, or Turinabol, is a synthetic anabolic-androgenic steroid derived from testosterone with structural modifications, including a 4-chloro group, which prevents aromatization to estrogen. These modifications enhance anabolic activity, promoting lean muscle growth and strength without significant fluid retention.With an anabolic-to-androgenic ratio of 54:6, Turinabol effectively stimulates protein synthesis, nitrogen retention, and red blood cell production, contributing to improved endurance and recovery. Its 17-alpha alkylated structure allows oral administration while maintaining bioavailability and effectiveness in muscle development.
