What Is Testosterone Cypionate?

Testosterone Cypionate is the 17β-cyclopentylpropionate ester of testosterone. The chemical name is androst-4-en-3-one, 17-(3-cyclopentyl-1-oxopropoxy)-, (17β)-. Its molecular formula is C₂₇H₄₀O₃ and the molecular weight is approximately 412.6 g/mol. The cypionate ester significantly slows the release of free testosterone after intramuscular administration, providing a longer duration of action compared with shorter esters such as propionate.

According to the USP monograph, Testosterone Cypionate powder contains not less than 97.0 percent and not more than 103.0 percent of C₂₇H₄₀O₃ on the dried basis. The corresponding injection is a sterile solution in a suitable vegetable oil that contains 90.0–110.0 percent of the labeled amount of the ester.

Research and Professional Context

Testosterone Cypionate has long been studied and utilized as a long-acting androgen. In laboratory settings it serves as a reference standard for androgen-receptor research, pharmacokinetic modeling of esterified steroids, and investigations of the hypothalamic-pituitary-gonadal axis. Pharmaceutical-grade material is also employed in regulated compounding and hormone-replacement contexts where USP compliance is required.

The 250 mg/ml strength is a widely recognized concentration that balances solubility, injectability and dosing convenience. The oil vehicle and ester combination produce a sustained release profile with an approximate half-life of 8–16 days depending on the specific formulation and individual factors.
