I've been using NO Explode with Cellmass for about two months. I'm not really sure if it's helped or not. I've put on a few pounds of muscle-weight but I really think it was due to adding two days of powertraining to my weekly routine. That stack is expensive and the wife feels there had better be more dramatic results or I drop it. When this supply runs out I'm going to try some of the Xyience stuff and see what happens there. If nothing better or worse happens, I'm going to stay with a muti-vitamin and fat burner and spend my money elsewhere (on the Camaro I'm trying to restore).
