I tried carnivor mass because it was on special. It's pretty awesome,I could see some effects within 3 days of taking it. I noticed fuller muscle pumps while lifting and 3 weeks in my lifts are consistently going up. I have tried alot of top notch mass gainers like monster mass,mhp up your mass and real mass,but carnivor mass is the best from which I have tried. Chocolate fudge tastes great. I would recommend it to any one who looking for serious clean bulk and strength. This is also ideal for hardgainers, try carnivor mass. The only problem I got with carnivor mass is the shake is very thick, and I'm not always able to gulp everything down but you can control that by taking fewer scoops. Overall I can say its a perfect mass gainer with beef protein, 125g of high impact reactive carbs, beef amino and creatine monohydrate.
