Sustanon 250 is a clear pale yellow solution for injection containing the active ingredient testosterone in 4 (250 mg/ml) separate forms. The active substances of Sustanon 250 are turned into testosterone by the body, which is a natural male hormone known as an androgen. Sustanon 250 is used in adult men for testosterone replacement to treat various health problems caused by a lack of testosterone (male hypogonadism), which should be confirmed by two separate blood testosterone measurements and also include clinical symptoms such as impotence, infertility, low sex drive, tiredness, depressive moods, and bone loss caused by low hormone levels. Sustanon 250 may also be used as supportive therapy for female-to-male transsexuals. However, the misuse of this medicine to enhance ability in sports carries serious health risks and is discouraged. Sustanon 250 should be administered by deep intramuscular injection. The standard treatment is usually one injection of Sustanon 250 every 3 weeks, and the dosage should be adjusted by the doctor in response to individual requirements.
