Testosterone cypionate is an esterified testosterone preparation intended for intramuscular administration. The cypionate ester slows the release of testosterone after injection.

The product name identifies a 10mL presentation and 250mg strength, although the precise concentration convention should be confirmed from its labeling. Pharmaceutical testosterone cypionate preparations are used for testosterone replacement in appropriately diagnosed deficiency.

Monitoring may include testosterone levels, hematocrit, prostate-related parameters, cardiovascular risk factors, and reproductive function.
