Buy Test Enanthate 250mg per ml, 1 x 10ml Vial Test Enanthate 250 (Testosterone Enanthate) is an oil based injectable steroid. It release testosterone slowly from the injection site (depot). 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 used regularly to treat cases of hypogonadism and other disorders related to androgen deficiency. Since patients generally do not self administer 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. Test Enanthate 250 has also been researched as a possible male birth control options. Regular injections will efficiently lower sperm production, a state that will be reversible when the drug is removed. With the current stigma surrounding steroids however, it is unlikely that such an idea would actually become an adopted practice. Similar to testosterone and its esters in physiologic activity, testosterone enanthate has the advantage of prolonged effect. In hypogonadal males the effect of a single injection of 250 to 500 mg of testosterone enanthate was observed to be maintained for 2 to 4 weeks, which is 2 to 4 times longer than the effect produced by a comparable dose of testosterone propionate.
