Sustanon is a trade name owned by Organon Pharmaceuticals for oil-based injectable blends of esterified testosterone compounds.


Sustanon 250 is a blend of four esterified testosterone compounds: [1]


Sustanon 100 was similar, though with three esters. This smaller dose was usually for pediatric use.

  • 20 mg testosterone propionate
  • 40 mg testosterone phenylpropionate
  • 40 mg testosterone isocaproate

Sustanon 100 has not been produced since 2009.[2]


The different testosterone esters provide for different half-lives. Esterization of the testosterone molecules provides for a sustained (but non-linear) release of testosterone hormone from the injection depot into the blood plasma. [3]


While the intention of the mixed testosterone esters in Sustanon is to provide more stable serum testosterone levels. [4], a single long-ester testosterone, such as testosterone cypionate or testosterone enanthate, may actually provide more stable serum testosterone levels.[medical citation needed]

Sustanon 250 is one of the most commonly used testosterone replacement treatments prescribed in the UK,US,Canada and Australia.

This form of testosterone is a popular choice of anabolic steroid among bodybuilders and athletes.[5]
