This injectable testosterone formulation merges five esters with varying absorption rates: acetate acts within hours, propionate and phenylpropionate offer mid-range release, and cypionate and decanoate extend activity over several days. The result is a blend that delivers both immediate testosterone elevation and long-term hormonal support. Athletes benefit from the fast onset of strength and energy, while longer esters maintain muscle-building and recovery. This structure reduces injection frequency while ensuring stable testosterone levels.
