Testosterone bucyclate

Testosterone Bucyclate is an androgen and anabolic steroid (AAS) medication which is used in veterinary medicine in Europe, specifically in dogs and cats. It is given by injection into muscle.

Pharmacology

As an AAS, testosterone bucyclate is an agonist of the androgen receptor (AR), similarly to androgens like testosterone and dihydrotestosterone (DHT). It has strong anabolic effects and weak androgenic effects, as well as no estrogenic effects or risk of liver damage at therapeutic doses.

Chemistry

Testosterone bucyclate, also known as testosterone cyclobutylcarboxylate, is a synthetic estrane steroid and a derivative of testosterone. It is an androgen ester—specifically, the C17β cyclobutylcarboxylate ester of testosterone—and it is therefore considered to be a natural and bioidentical form of testosterone.

History

Testosterone bucyclate was first described in 1979 and was introduced for veterinary use in Europe by the 1980s.

Society and culture

Testosterone bucyclate is marketed in Europe for veterinary use under the brand names Proluton C and Reandron 1000.
