I recently tried a new mass gainer (to me). Carnivor Mass from Musclemeds is a beef protein mass gainer. I purchased the chocolate fudge flavor and the taste is great. Its good for one tub but I cant keep drinking the same flavor, I get tired of things quickly. The directions say to take 4 scoops but I find 3 scoops to be perfect for me. My muscles feel even more pumped than normal when I'm working out. After one large tub of carnivor mass I see a difference in size, I have gained about 8 pounds. However, I used this to help me build size and strength, I'm not worried about physique at this time. I drank a large shake every night before bed and I lifted very heavy in the gym. I would not take this product if I was worried about physique as it will put on some extra weight. Great mass gainer for anyone who is still bulking this season.
