A complex testosterone profile, this blend includes esters ranging from short-acting propionate to long-acting decanoate. Propionate provides immediate elevation, phenylpropionate and isocaproate extend effects over the medium term, while decanoate supports long-lasting testosterone stability. Isocaproate’s role enhances release consistency and reduces frequency of administration. This formulation ensures steady androgen levels for optimal strength, lean mass retention, and metabolic efficiency throughout a full cycle.
