HPLC 99.68% Purity Testosterone Propionate/Test Prop CAS:57-85-2

Testosterone Propionate is a pure testosterone hormone. Although synthetic it is a perfect replica of the primary naturally produced male androgen testosterone. By design, the hormone is attached to the Propionate (propionic acid) ester, a small/short ester that enables the hormone’s release time to be controlled. Without an ester, the hormone would disperse and dissipate rapidly post administration. By attaching the ester, this promotes a controlled release and allows the individual to inject the hormone less frequently. Once Testosterone Propionate is injected, the ester slowly begins to detach from the hormone. As the ester is detached the testosterone hormone begins to release into the blood. The half-life of Testosterone Propionate is approximately two days, which is substantially longer than ester free testosterone, which carries a half-life a little less than 24 hours.

Testosterone Propionate Function:
Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing Osteoporosis (loss of bone density) and possible protection against heart disease. Testosterone is also responsible for normal growth and development of male sex organs and maintenance of secondary sex characteristics. Secondary sex characteristics are specific traits that separate the two sexes, but are not directly part of the reproductive system, for example: chest and facial hair, a distinguished jaw line, broad shoulders and increased muscle mass. Testosterone binds to the Androgen Receptors (AR), which thus causes accelerated muscle gain, fat loss, and muscle repair and growth. These mechanisms are stimulated by activation of the Androgen Receptors (either directly or indirectly as DHT).

Testosterone Propionate side-effect:
There are many possible side-effects associated with Testosterone Propionate use. This product has a high level of aromatization into estrogen and coverts to DHT (dihydrotestosterone) as well. Testosterone can convert to estrogen, the female sex hormone, creating a high risk of gynecomastia (formation of breast tissue in males). Also, supplementing Testosterone to your body will result in the shutting down of the body’s natural production of the hormone. The severity of side effects depend mostly on the dose and duration of circulating free testosterone and it’s conversion to estrogen and DHT. Testosterone’s anabolic/androgenic effects are dependant upon also dosage; the higher the dose the higher the muscle building effect. Testosterone typically promotes aggressive and dominant behavior.

Testosterone is the best mass builder known to man and recommended as the base of any mass building cycle.
