Thank you IronFlex Supplements for the opportunity to do this. The Nasty Mass cycle has ended I am out of ammo. I believe this was a great supplement for adding size. I also would think it would be good for strength (at my age I do not go for PR's). I actually finished the run last Sunday but I wanted to give my body a few days to return to "Normal" after the Christmas eating frenzy. First the negatives, I did have some Blood Pressure issues with the Nasty Mass and I had headaches most of the time I was running it (headaches were minor) this could have some thing to do with my age? Overall I really like this supplement, I gained size, aggression in the gym, but none outside of the gym. I woke up every morning anxious to train. Once I started training the time went very fast and I trained quicker than usually with out trying. One of the side effects I noticed (which I liked) it curbed my hunger and made it easier to eat clean. Before Body Weight 180lbs Waist 36" Chest 42" Bicep 16" Neck 16 1/2" After Body Weight 188 (was up to 194lbs day after Christmas) Waist 36" Chest 44" Bicep 16 1/2" Neck 17" I gained 8 solid pounds add 2" to my chest and 1/2" on my arms, I would call that a success !!! Nasty Mass Rocks!!
