Neotest 250 (testosterone decanoate)
Estrogenic Activity moderate
Progestational Activity low
Testosterone decanoate is a slow-acting injectable form of the primary male androgen testosterone. This steroid is mostly commonly identified as part of the four-ester blend in Sustanon® 250, but here is described as a standalone agent. The long decanoate ester used to make testosterone decanoate creates a drug with pharmacokinetic properties similar to nandrolone decanoate, providing a sustained release of hormone (in this case testosterone) for approximately three weeks following injection. Testosterone decanoate is slightly slower-acting than the commercially available esters cypionate and enanthate, and could provide a slightly less frequent injection schedule in comparison.
