Testosterone enanthate is an oil based injectable steroid, designed to slowly release testosterone from the injection site. Once administered, serum concentrations of this hormone will rise for several days, and remain markedly elevated for approximately two weeks. It may actually take three weeks for the action of this drug to fully diminish.

For medical purposes this is the most widely prescribed testosterone, used regularly to treat cases of hypogonadism and other disorders related to androgen deficiency. Since patients generally do not selfadminister such injections, a long acting steroid like this is a very welcome item. Therapy is clearly more comfortable in comparison to an ester like propionate, which requires a much more frequent dosage schedule.

Testosterone Enanthate use for female:

Metastatic mammary cancer - Testosterone Enanthate Injection, may be used secondarily in women with advancing inoperable metastatic (skeletal) mammary cancer who are one to five years postmenopausal. Primary goals of therapy in these women include ablation of the ovaries. Other methods of counteracting estrogen activity are adrenalectomy, hypophysectomy, and/or antiestrogen therapy. This treatment has also been used in premenopausal women with breast cancer who have benefited from oophorectomy and are considered to have a hormone-responsive tumor. Judgment concerning androgen therapy should be made by an oncologist with expertise in this field.
