Testosterone propionate/testosterone phenylpropionate/testosterone isocaproate/testosterone decanoate (TP/TPP/TiC/TD), also known as a Sustanon 250 (Organon), is an injectable combination medication of four testosterone esters, all of which are androgens/anabolic steroids.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Pharmacology

The four testosterone esters are as follows;

• 30 mg testosterone propionate<ref name=":0" />
• 60 mg testosterone phenylpropionate<ref name=":0" />
• 60 mg testosterone isocaproate<ref name=":0" />
• 100 mg testosterone decanoate<ref name=":0" />

Cumulatively, a 1 ml of the oil solution contains exactly 250 mg of above mentioned testosterone esters.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> This particular numerical value is clearly depicted in the name of the product, Sustanon 250.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

They are provided as an oil solution and are administered by intramuscular injection.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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. Sustanon 100 is administered once every 2 weeks and Sustanon 250 is administered once every 3 to 4 weeks.<ref name="Llewellyn2011">Template:Cite book</ref>

Sustanon is the preferred method of testosterone replacement in the United Kingdom as detailed in the British National Formulary.Template:Citation needed There was a brief shortage of Sustanon 250 during late 2011, due to shifting of manufacturing site,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and a further shortage in mid-2012 due to manufacturing problems.Template:Medcn
