Pharmacodynamics<unk>  is a prodrug of<unk>  and is an androgen and anabolic–androgenic steroid (AAS). That is, it is an agonist of the androgen receptor (AR). Pharmacokinetics The pharmacokinetics of<unk>  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<unk>  enanthate. As such,<unk>  and<unk>  enanthate are considered to be "functionally interchangeable" as medications. For reference,<unk>  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<unk>  levels result with it, with levels initially being elevated and supraphysiological. The pharmacokinetics of<unk>  have been studied and reported.
