I am gonna take a guess that most of the mod, vets, and others are gonna say that 10 weeks on any 17aa oral is gonna be too much. I know that anavar is a milder steriod, all oral have a negative effect on the liver and the length should be kept to a minimum. i Cant comment on the anavar and creatine except that i have hear that it i great together. A good brand of creatine? I try to stick with your bigger companies, I.E. Twinlab and such.For the price, i didnt mind GNC's plain creatine monohydrate.
