Testosterone cypionate is one of the most commonly prescribed forms of testosterone replacement therapy (TRT). It is a synthetic ester of testosterone, meaning it is a modified form that allows the hormone to be released slowly into the bloodstream after injection. Typically, it is administered via intramuscular injection, often into the gluteal muscle, every one to two weeks. This slow-release mechanism gives it a long half-life, making it ideal for maintaining steady testosterone levels over time.
