I tried Animal Cuts a few years back and I got the worst side effects...vomiting, diarrhea, heart burn, sweating all the time. I don't care how good the results are supposed to be, I felt like crap after taking those pill packs and switched Oxy Elite Pro
Of course it's better than anything over the counter. I'm not into flaming, so I won't, but this is a very uninformed question. It's like comparing creatine to Test Prop.
I have only ever found one or two stacks that will yield noticeable results even when not being completely strict with my nutrition. It all comes down to cardio and nutrition.
