Hopefully some of the more tecnically inclined will chime in as well, but I can give you my experience. I found in the cycle I'm just about to complete that the M4OHN and M5AA will do the trick. Since neither is gonna eat you alive (like M1T), you'll find plenty of energy I think and shutdown effect seems quite managable. I actually ran 200mg 1T t/d with these, and didn't suffer lethagy, so just the 2 should be fine. I got up to 40mg M4OHN and 100mg M5AA daily, spread out through the day, and have found hardness and vascularity as well as strength. Be patient, though. I was 2 weeks in, thinking "this sh!t isn't working" when in truth, it just takes some time. Keep your diet in check, and I'd say shine the 4AD--it will just bloat you, not cut you.
