Message: | 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.[medical citation needed]
Sustanon is the preferred method of testosterone replacement in the UK as detailed in the British National Formulary.[citation needed] There was a brief shortage of Sustanon 250 during late 2011, due to licensing problems and a further shortage in mid-2012 due to manufacturing problems.
This form of testosterone is a popular choice of anabolic steroid among bodybuilders and athlete.
