What is Sustanon 250 ?

Sustanon 250 is an injectable testosterone medication containing four testosterone esters. It is used in some countries for testosterone replacement in men with medically confirmed testosterone deficiency.

Composition of Sustanon 250

A standard 1 mL ampoule contains:

The 250 mg refers to the combined weight of the four esters, not 250 mg of pure testosterone.

Main effects

• Supports normal testosterone levels in people with a confirmed deficiency.

• Helps maintain muscle mass and bone density.

• May improve libido and other symptoms caused by low testosterone.

• Can increase red blood cell production.

Muscle gain can occur, but using testosterone without a medical indication carries significant health risks.

Side effects and risks

Potential adverse effects include acne, fluid retention, increased blood pressure, elevated red blood cell count, cholesterol changes, and suppression of natural testosterone and sperm production. Fertility may be reduced, sometimes substantially.

Medical supervision is important, including monitoring testosterone levels, blood counts, blood pressure, and other tests as appropriate.

Dosage and administration

Sustanon 250 is administered by intramuscular injection. The prescribed dose and interval depend on the diagnosis, blood test results, symptoms, response to treatment, and local prescribing guidance. A bodybuilding cycle is not the same as medically supervised testosterone replacement.
