Stacker 2 Ephedra-free is a part of the weight loss supplement line, developed by NVE Pharmaceuticals. This formula has been on the market for almost 20 years and hasn't changed during that entire time: simply because it works and meets the needs of users who are looking for a fat burner which doesn't feel too potent but is still effective. If you're looking for something stronger, check out our Stacker 4, or Black Burn.
At the time that the composition of Stacker2 Ephedra-free was developed, this was a unique product that enabled effective fat burning without unpleasant side effects, such as nervous agitation. In the meantime, much has changed and more powerful versions of Stacker have been developed. Even so, this product is still just as popular as ever and has been one of the most successful formulas in the United States for many years.
