Test Prop is a short acting oil-based injectable formulation of testosterone. It is an efficient hormone for the treatment of low testosterone.

Testosterone inhibits gonadotropin secretion from the pituitary gland and ablates estrogen production in the ovaries, thereby decreasing endogenous estrogen levels. It promotes the maintenance of male sex characteristics and is indicated for testosterone replacement in hypogonadal males. Testosterone is an essential hormone produced by men and women that affects our physical, mental and sexual wellbeing.

Test Prop (Testosterone Propionate) is an ester of testosterone with a propionate substitution at the 17-beta position. By attaching the Propionate ester to the hormone, it would allow for the hormone's release time to be controlled and provided a more efficient means in maintaining stable blood levels.

Testosterone Propionate is used in treating menopausal issues, chronic cystic mastitis, excessive lactation and endometriosis. It is used for treatment of male androgen deficiency. It is the most commonly used testosterone for female medical treatment.
