What is testosterone propionate?

Testosterone propionate has a specific androgenic effect: it stimulates the development and function of the external genitalia, prostate, seminal vesicles, and the secondary sexual characteristics in men (voice, hair). It participates in the formation of the body constitution and sexual behavior in men, stimulates the libido and potency, and stimulates spermatogenesis. It reduces the production of luteotrophic and follicle-stimulating hormone.

Testosterone is an antagonist of female sex hormone – estrogen, has an antitumor effect in breast tumors in women. It has anabolic effects, resulting in a stimulation of protein synthesis, decreasing fat deposition, keeping necessary things for the synthesis of protein, potassium, phosphorus, sulfur, and enhancing fixation of calcium in the bones and increasing muscle mass. With sufficient protein diet it stimulates the production of erythropoietin.

After testosterone propionate injection it is slowly absorbed from the injection site. Circulating testosterone gets into the target organs where it is restored to 5-α- dehydrate testosterone, which interacts with the receptors of the cell membrane and penetrates the cell nucleus. Up to 98% of the drug in the blood binds to plasma proteins, mainly globulins. It is metabolized in the liver to inactive metabolites that are excreted in the urine. Approximately 6% of the drug is excreted unchanged in the intestinal condition.
