Product Overview

Designed for time-released testosterone delivery, this mix includes esters with short, medium, and long half-lives. Propionate acts within hours, phenylpropionate and isocaproate maintain levels for several days, and decanoate provides extended support. Isocaproate enhances solubility and helps balance the transition between esters. Together, they form a comprehensive anabolic base that supports physical performance, testosterone replacement, and consistent hormonal levels with a minimized injection schedule.
