Androgenic hormones

Class Summary

Testosterone is the main androgenic hormone predominantly formed in the interstitial (Leydig) cells of the testes. In target tissues, it is converted to the more active form (DHT) by 5-alpha reductase. Testosterone controls the development and maintenance of the male sex organs and the male secondary sex characteristics. It also produces systemic anabolic effects to include increased erythropoietin, increased protein production, and increased retention of calcium. Testosterone is a schedule C-III controlled substance.

Testosterone cypionate or enanthate (Andro-LA, Delatest, Depo-Testosterone)

Testosterone cypionate or enanthate promotes and maintains secondary sex characteristics in males with androgen deficiency.
