Pharmacology

The four testosterone esters are as follows;

Cumulatively, a 1 ml of the oil solution contains exactly 250 mg of above mentioned testosterone esters.[2][3] This particular numerical value is clearly depicted in the name of the product, Sustanon 250.[4]

They are provided as an oil solution and are administered by intramuscular injection.[5] 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.[6]

Sustanon is the preferred method of testosterone replacement in the United Kingdom as detailed in the British National Formulary. There was a brief shortage of Sustanon 250 during late 2011, due to shifting of manufacturing site,[7] 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 athletes.
