Testosterone is the primary male sex hormone. It is the responsible for producing mainly male-specific sexual traits. When synthesized, it is usually attached to an ester to delay its release into the body. Testosterone Propionate is the shortest commonly ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, testosterone propionate typically needs to be injected every other day at a minimum. Anecdotally, testosterone propionate causes the least side effects and the least bloating; these side effects usually subside very quickly when use is ceased.
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, enhancing fixation of calcium in the bones and increasing muscle mass. With sufficient protein diet it stimulates the production of erythropoietin.
Effects
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.

Pharmacology
Testosterone is a steroid hormone from the androgen group. Testosterone is primarily secreted from the testes of males. In females, it is produced in the ovaries, adrenal glands and by conversion of adrostenedione in the periphery. It is the principal male sex hormone and an anabolic steroid. In both males and females, it plays key roles in health and well-being. Examples include enhanced libido, energy, immune function, and protection against osteoporosis. On average, the adult male body produces about twenty times the amount of testosterone than an adult female’s body does. In the body, this ester form of testosterone is hydrolyzed rapidly and become actively available as testosterone.
Testosterone Propionate is a short acting oil-based injectable formulation of testosterone. Testosterone inhibits gonadotropin secretion from the pituitary gland and ablates estrogen production in the ovaries, thereby decreasing endogenous estrogen levels. In addition, this agent promotes the maintenance of male sex characteristics and is indicated for testosterone replacement in hypogonadal males. (NCI04)
Background
