How Sustanon 300 Works
Testosterone binds to androgen receptors, stimulating protein synthesis, nitrogen retention, and red blood cell production.
With its multi-ester design, Sustanon 300 delivers an immediate testosterone boost from Propionate, while the longer esters (Decanoate, Isocaproate) maintain levels for up to two weeks.
This makes it a reliable choice for both hormone replacement therapy (HRT) and performance enhancement cycles.
