Product Overview

A complex testosterone mix combining esters with different half-lives, this blend is structured to mimic natural testosterone rhythms. Propionate initiates fast anabolic activity, phenylpropionate and isocaproate bridge the mid-range, and decanoate prolongs hormonal action. Isocaproate enhances the pharmacological profile with improved absorption and sustained effects. Used in therapeutic and performance settings, this mix supports muscle retention, strength, and balanced endocrine response, while limiting the need for frequent dosing.
