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.{{Cite web|title=Sustanon 250: total description and usage tips!|url=https://fitnesstribe.net/sustanon-250.html|access-date=2021-03-02|website=fitnesstribe.net|language=en-US|archive-date=2023-12-08|archive-url=https://web.archive.org/web/20231208124345/https://fitnesstribe.net/sustanon-250.html|url-status=dead}}
