Testosterone propionate/testosterone phenylpropionate/testosterone isocaproate

Testosterone propionate/testosterone phenylpropionate/testosterone isocaproate (TP/TPP/TiC), sold under the brand name Sustanon 100 (Organon), is an injectable combination medication of three testosterone esters, all of which are androgens/anabolic steroids. They include:


 * 20 mg testosterone propionate
 * 40 mg testosterone phenylpropionate
 * 40 mg testosterone isocaproate

They are provided as an oil solution and are administered by intramuscular injection. The different testosterone esters provide for different elimination half-lives in the body. Esterification of testosterone provides for a sustained but non-linear release of testosterone hormone from the injection depot into the circulation.

The medication was a smaller dose than Sustanon 250 and was usually reserved for pediatric use.

Sustanon 100 has not been produced since 2009. Sustanon 100 is manufactured in India by Zydus.
