Description
Primocyl E® is a sterile oily solution containing methenolone enanthate, an esterified form of methenolone. Methenolone is a dihydrotestosterone-derived steroid compound, while the enanthate ester is attached to the 17β-hydroxyl group and increases the lipophilic character of the molecule.
The oily injectable form is suited to this esterified steroid compound for deep intramuscular administration. After injection, the oil phase forms a depot from which the esterified substance is released before enzymatic hydrolysis of the ester bond yields methenolone. In this type of preparation, the enanthate ester structure and oil-based vehicle are important factors influencing the depot character of the product.
