Equidex 200 is identified with boldenone, specifically boldenone undecylenate, an esterified anabolic-androgenic steroid. The undecylenate ester gives the compound a prolonged release profile following injection.

Boldenone was developed primarily for veterinary use and is not an approved human testosterone-replacement medicine. It acts through androgen receptors and can influence protein metabolism, erythropoiesis, and endogenous hormonal signaling.

The supplied product specifies a 200-strength injectable presentation. Exposure to anabolic-androgenic steroids can affect hematocrit, cholesterol levels, blood pressure, fertility, and natural hormone production, making appropriate medical oversight important.
