Testo-P®

What Is Testosterone Propionate 100mg?

Testo-P by Sigma Pharmaceuticals contains testosterone propionate 100mg per mL. The propionate ester is one of the shortest testosterone esters, so the hormone is released quickly and cleared from the body within a few days. Its half-life is less than one day, which is why it was traditionally administered more frequently than longer esters.

Medical Use and History

Introduced in 1937, testosterone propionate was the first commercially available testosterone ester. For decades it was used to treat male hypogonadism and delayed puberty, before longer-acting esters became the standard in replacement therapy. It remains an important reference compound in endocrinology and pharmacology research.
