estosterone Enanthate (X-prolongat, Enanject,Testoxyl Enanthate 250) is an injectable steroid, its active substance is Testosterone Enanthate.
Testosterone Enanthate is probably the most commonly used form of testosterone by both athletes and bodybuilders alike.
Testosterone Enanthate is an oil based injectable steroid, which is designed to slowly release testosterone from the injection site. This slow release delivery leads to an elevation in testosterone levels lasting for approximately two weeks (it may even take as long as three weeks for the drug levels to fully diminish). Due to its relatively long activity level, Testosterone Enanthate is favored by the medical profession and is primarily used to treat cases of hypogonadism and similar disorders where low androgen levels are at fault. As with all testosterone products it has strong anabolic and androgenic activity. Gains in strength and muscle mass are notable, along with an increase in libido. It has also been noted that a relief in tendon pain and an increase in stamina are direct effects of Testosterone Enanthate administration. This is probably due to increased water retention coupled with an increase in red blood cells – leading to a greater oxygen uptake in the blood.
Testosterone is a highly anabolic and androgenic hormone, it has an anabolic (muscle building) as well as anabolic rating of 100 each, respectively. Testosterone Enanthate exerts the majority of its effects by promoting increased nitrogen retention in the muscle. Testosterone Enanthate is also known to increases levels of the growth factor IGF-1 in both the muscle tissue as well as the liver. This steroid also increases the activity of satellite cells, which are cells that play an active role in repairing exercise-damaged muscle. Testosterone Enanthate exerts these effects primarily by genomic mechanisms, meaning that it binds to the androgen receptor (AR) thus initiating gene transcription. This stimulation of the AR promotes various of the AR dependant mechanisms for both muscle gain and fat loss, as well as reducing catabolic glucocorticoid hormones, and increasing red blood cell production.
