Sustanon 100 Injection (Testosterone Propionate, Phenylpropionate & Isocaproate)

Sustanon 100 Injection is a testosterone replacement therapy (TRT) medicine used for the treatment of male hypogonadism — a condition in which the body fails to produce enough testosterone.
It contains a unique blend of three testosterone esters — Propionate, Phenylpropionate, and Isocaproate — that provide both rapid onset and sustained release of testosterone, maintaining optimal hormone balance in adult males.

This injection helps restore testosterone levels in the blood, improving symptoms such as low libido, erectile dysfunction, fatigue, mood swings, and muscle weakness.

Mechanism of Action

Sustanon 100 Injection combines three testosterone esters that are hydrolyzed to release free testosterone gradually into the bloodstream.
This helps maintain stable testosterone levels for a prolonged duration, mimicking the natural secretion of the hormone.
The hormone then binds to androgen receptors, enhancing protein synthesis, muscle growth, and sexual function.
