Animal Stak FAQ #4: Can I "stack" Animal Stak with Animal M-Stak?
Q: Can I "stack" Animal Stak with Animal M-Stak?
A: Absolutely. In fact, this would be a solid stack, no doubt. Both promote anabolism in their own unique way and neither formulas overlap. M-Stak enhances protein synthesis and "nutrient partitioning" while Stak increases and optimizes the utilization of anabolic hormones.
difference between m stack and stack
From what I have gathered is that stack is a test booster and mstack is not. Is there any other differences between the two products?
