I have done 5 or 6 cycles of Havoc at varying doses. I have noticed NO reduction in effectiveness from cycle to cycle and I am in the best shape of my life.
This last cycle, I started playing with a formula designed to amplify the effects of androgens on the AR...and this has been the best cycle yet, even at moderate dosing (40mg a day.)
I am holding steady at anywhere from 210-215 all the while leaning up ( I am lean bulking with DCP/Leviathan/Green Tea/CLA/Fish Oil and low dose Sesathin.)
