What is Testosterone decanoate?

Description

Testosterone Decanoate is one of the many esterified forms of testosterone and is a long form of the testosterone as it offers a long half life after administration. This is actually an androgen and anabolic steroid and a testosterone ester, a potent long acting injectable male synthetic hormone. Testosterone Decanoate is second longest acting form of testosterone after Testosterone Undecanoate. As with any other form of testosterone, the only difference between them is in the half life (the release time of the hormone after it got administered).

Chemical properties

White or almost white powder.

The Uses of Testosterone decanoate

Testosterone decanoate is an androgen that mainly used by men to maintain the second sexual sign, sexual desire and male psychology. It is an steroid indicated for testosterone replacement therapy in sterilization, missing testicle, hypopituitarism, and osteoporosis.

Definition

ChEBI: Testosterone decanoate is a steroid ester.

Mechanism of action

Testosterone binds to the androgen receptor (AR), and the ligand-receptor complex translocates to the nucleus and binds to androgen response elements (AREs) on chromosomal DNA, thereby modulating transcription of a set of androgen-responsive genes. Testosterone can also be converted to estrogen and has a similar regulatory action on genes containing estrogen response elements (EREs).
