In addition, it is also used in hormone therapy for transgender men.It is given by injection into muscle or subcutaneously, once every one to four weeks, depending on clinical indication.TC; TCPP; Testosterone cipionate; Testosterone cyclopentylpropionate; Testosterone cyclopentanepropionate; Testosterone 17β-cyclopentylpropionate are all other names of Testosterone cypionate.
To begin Testosterone cypionate is used primarily in androgen replacement therapy. In addition, it is currently FDA approved for the treatment of primary or hypogonadotropic hypogonadism (either congenital or acquired).

Testosterone 17β-cyclopentylpropionate, is a synthetic androstane steroid and a derivative of testosterone. It is an androgen ester (highly reactive compound) formed from the chemical composition of the above mentioned elements ; specifically, it is the C17β cyclopentylpropionate (cypionate) ester of testosterone
The pharmacokinetics of testosterone cypionate via depot intramuscular injection, including its elimination half-life and duration of action, are said to be extremely comparable to and hence essentially the same as those of testosterone enanthate. As such, testosterone cypionate and testosterone enanthate are considered to be “functionally interchangeable” as medications. For reference, testosterone enanthate has an elimination half-life of 4.5 days and a mean residence time of 8.5 days and requires frequent administration of approximately once per week. Large fluctuations in testosterone levels result with it, with levels initially being elevated and supraphysiological.
