Sustanon 100 Injection

Sustanon 100 Injection is a clinically formulated testosterone replacement therapy (TRT) used for the treatment of male hypogonadism — a condition in which the body fails to produce sufficient levels of testosterone. It contains a blend of three testosterone esters that ensure both rapid and sustained release of testosterone, effectively restoring hormonal balance.

This medication helps relieve symptoms associated with low testosterone such as fatigue, low libido, muscle loss, mood swings, and reduced bone density. It is prescribed only to men with clinically confirmed low testosterone levels and must be administered under strict medical supervision.

Uses of Sustanon 100 Injection

• Treatment of male hypogonadism due to low testosterone levels

• Management of symptoms such as low libido, fatigue, and muscle weakness

• Supports bone density, muscle growth, and red blood cell production

• Used as testosterone replacement therapy (TRT) in adult males

How Sustanon 100 Works

Sustanon 100 contains three different testosterone esters that act at varying rates of absorption:

• Testosterone Propionate – provides a quick onset of action

• Testosterone Phenylpropionate and Testosterone Isocaproate – maintain prolonged testosterone release

Together, these esters ensure a steady testosterone level in the bloodstream, improving physical stamina, muscle mass, bone health, and sexual function.
