To make Equipoise, a double bond was added between carbon atoms 1 and 2 of the Steran Nucleus of Testosterone. What does this mean? Well, first of all, since Equipoise was created by one simple modification in the testosterone molecule, you could rightly suspect that it shares many similarities with it. Equipoise is just as anabolic as testosterone (as you can tell by its anabolic rating above), but only half as androgenic. Those ratings can be quite deceiving though, as I don't know anyone who would claim that you can gain as much weight on Equipoise as you can gain on an equal amount of testosterone (even though strength gains from the two compounds are very similar).
