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.
Side effects such as water retention usually occur when using Testosterone Enanthate. Gyno, increased rate of hair growth, back acne, increased blood pressure, and aggressiveness, both in the gym and out, are possible when using this steroid. The liver is accustomed to processing testosterone, so liver toxicity is normally not a concern except at extremely high doses.
