Pharmacom Labs is a name usually associated with concentrated injectables, and Pharma Test C250 is the baseline-strength cypionate in that line: a 10 ml vial holding 250 mg per millilitre. Its label carries the scratch panel the manufacturer uses so a unit can be checked against its own records.
Testosterone cypionate is the natural androgen with a cyclopentylpropionate ester attached, and the ester is the part that dictates how slowly the hormone leaves the injection site. As a long-ester oil solution it behaves as a depot preparation and is given intramuscularly.
