10-12 weeks is not enough for equipoise. it is not quite equiv to primo--there is some conversion to estrogen (little) and the gains are virtually perm like primo. the benefit is that you have an elevated hematocrit for months after you stop so you can use that to your advantage. You also need to be wary if you get anxiety, you need to drop the dose, split them, then ramp back up. it is hit and miss until you get the dose right (but that is not everyone).
you will also fail a bloodtest if you are a contender in the kentucky derby.
sustenton is fine-my fav, but you really need to pin every other day---i like it for long cycles b/c of the four diff tests in it--no science to back that up, just bro-ology
