Testosterone Enanthate is an oil based injectable, designed to release testosterone slowly from the injection site. Once administered, serum concentrations of this hormone will rise for several days, and remain markedly elevated for approximately two weeks. For medical purposes this is the most widely prescribed testosterone used regularly to treat cases of hypogonadism and other disorders related to androgen deficiency.
As with all testosterone products it has a strong anabolic activity, with a pronounced androgenic component. Thus it can provide significant gains in strength and muscle mass, as well a noticeable increase in libido. An added benefit, with all testosterone products is the relief of tendon pain, faster recuperation and an increase in the level and duration of physical output due to the oxygen rich blood along with an increase of red blood cells. Although when taken at reasonable dosages aromatisation should not be a problem, some patients may wish to use an anti-estrogen, this case a low dosage of Tamoxifen Citrate or Mesterolone would be appropriate.

The use of HCG (Human Chorionic Gonadotropin) in addition to Clomiphene Citrate and Tamoxifen Citrate may also be beneficial at the conclusion of use in order to ensure balance in the hormone system.

Although this particular ester is active for a much longer duration, typically a 200 to 300mg injection is taken on a weekly basis in order to keep blood levels more uniform.
