There are two types of Dianabol that shoppers will encounter no matter where they look: pharmaceutical grade Dianabol and underground lab (UGL) grade Dianabol. As the names imply, pharmaceutical grade drugs are those which are manufactured by fully licensed and FDA-approved pharmaceutical companies that manufacture these drugs for sale on the prescription market. However, in the case of off-label use for bodybuilding and athletic purposes, these drugs are often diverted clandestinely into the black market. UGL products are simply manufactured by unlicensed, unapproved, and often amateur underground laboratories that sell their products for far cheaper than their pharmaceutical grade counterparts.
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.
