We designed both the Stak and M-Stak to be natural anabolics, but each works differently. Stak is a natural hormone booster. It works with your body to help enhance key anabolic hormone levels, including testosterone.
Animal M-Stak, on the other hand, works to promote anabolism by increasing protein synthesis, nutrient portioning, nitrogen retention, all the while reducing muscle catabolism. In short, Animal Stak can help with performance and strength whereas Animal M-Stak can help with gaining lean mass and size. You can combine the two to get the best of both worlds.
No, there is no need to do so. Our products increase your natural hormone production by means of natural ingredients, not by introducing outside hormones to the system. Therefore, there is no shutdown, rebound, etc.
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.
Absolutely. Using a fat-burner along with Stak will not interfere with its effects on natural hormone production. Just be sure to leave 3-4 hours in between the time you use the fat burner and the time you take Stak. In such case, take your fat burner pre-workout as you normally would and use your Stak either a couple of hours before or after training. While it may not be completely necessary to divide the dosing, doing so will ensure optimal absorption.
