I would have used less had I had another chance to go around and in the future as I continue to compete in bodybuilding into my early 40s I'm probably never going to go much over 500 total milligrams because to me it seems my anabolic sensitivity so high that I just don't need much more than that and north of that my psychological side effects are so nasty it's absolutely just not worth it to me anymore
