Sustanon
Encyclopedia
Sustanon 250 is a trade name for an oil-based injectable blend of four ester
ized testosterone
compounds:
Sustanon 100 is similar, though with three esters. The smaller dose is for pediatric use.
The different testosterone esters provide for different half lives. Esterization of the testosterone molecules provides for a sustained (but non-linear) release of testosterone from the injection depot into the blood plasma
.
While the intention of the mixed testosterone esters in Sustanon is to provide more stable serum testosterone levels, a single long-ester testosterone, such as testosterone cypionate or testosterone enanthate, may actually provide more stable serum testosterone levels. It is the preferred method of testosterone replacement in the UK as detailed in the British National Formulary

Sustanon is a fairly popular anabolic steroid
product among those that use anabolic steroids for muscle building purposes and other reasons such as andropause
