While we are familiar with the Propionate ester the remaining three esters that create Sustanon-250 are almost always found as part of a mixture or compounded anabolic androgenic steroid .
Developed by Organon, the original idea behind Sustanon-250 was to provide a testosterone form well-suited for hormone replacement therapy that would only needed to be administered once every few weeks and for all intense purposes the idea was a success. For the performance enhancing athlete Sustanon-250 can be a fine choice but the idea of injecting only once or twice a month is not applicable here. As a performance enhancer this testosterone like all forms will need to be administered on a more frequent basis. This mixture carries with it two fast, short esters, Propionate and Pheylpropionate, a longer more moderate ester Isocaproate and the very slow and long Decanoate ester. In order to keep testosterone levels stable and at their peak most athletes will inject Sustanon-250 at a minimum of every 3 days and more commonly every other day for optimal results.

It could be argued that aromatization is a non-issue, as an . could always be employed to counter estrogen conversion. This is true, but I believe there is a simpler way to go about it. In my opinion, the ideal pre-contest MPD cycle should consist of a low dose of testosterone propionate (150-200 mg/week), as at least some estrogen is needed to maintain a healthy looking skin tone. This should be combined with 2-3 other anabolics; preferably 1-2 oral anabolics and 1-2 injectables anabolics. Some good examples of orals include: Anavar, Epistane, and Turinabol. As for injectables, most people usually find the following drugs to be compatible: Primo, Boldenone, and Dihydroboldenone (1-testosterone).
