Oxandrolone (17β-hydroxy-17α-methyl-2-oxa-5α-androstan-3-one) is a synthetic oral anabolic-androgenic steroid (AAS) derived from dihydrotestosterone (DHT). Characterized by a unique substitution of an oxygen atom for the carbon at the C-2 position in the A-ring, oxandrolone exhibits a high anabolic-

Nandrolone decanoate (ND) is a long-acting injectable ester of the anabolic-androgenic steroid (AAS) nandrolone (19-nortestosterone). Characterized by a high anabolic-to-androgenic ratio, ND has been utilized clinically for decades to treat conditions involving protein catabolism, bone density loss,

Testosterone enanthate (TE) is a long-acting esterified formulation of the primary endogenous androgen, testosterone. Since its clinical introduction in the 1950s, it has served as a cornerstone for testosterone replacement therapy (TRT) in male hypogonadism and a reference compound in clinical rese

Stanozolol is a synthetic anabolic-androgenic steroid (AAS) derived from dihydrotestosterone (DHT). Characterized by a high anabolic-to-androgenic ratio, it is clinically distinguished by its pyrazole ring modification and 17α-alkylation. Originally developed for the treatment of hereditary angioede

Testolone (RAD-140) is a potent, non-steroidal selective androgen receptor modulator (SARM) originally developed by Radius Health, Inc. It was designed to overcome the limitations of conventional androgen therapy, such as prostate enlargement and virilization, by exhibiting high tissue selectivity.

Trenbolone acetate (TBA) is a potent synthetic 19-nortestosterone derivative classified as an anabolic-androgenic steroid (AAS). Originally developed for veterinary applications—specifically to increase muscle mass and feed efficiency in beef cattle—TBA has become a focal point of pharmacological in
