What You Should Know
Stacker 2 derives its name from the term “stack” or “ECA stack”. ECA is an acronym for ephedrine, caffeine and aspirin. When “stacked” or combined correctly it is said to be a fat burner and energy booster. Originally, this product contained ephedrine. The ephedrine has been substituted with a combination of ingredients, called a Proprietary Formula, that supposed to work similar to ephedrine. The official website of NVE Pharmaceuticals, the maker of the product, sells only the ephedrine free version. Be aware that Stacker 2 with the ephedrine formula is still being sold on online stores all over the web.
The official NVE Pharmaceuticals website is attractive if you like flash and sexy videos. The company manufactures and markets a variety of weight loss products and energy drinks. To obtain product information much beyond an ingredients list one has to go elsewhere. The product is inexpensive, less than $20 for a hundred tabs, and available at discounts and in a variety of quantities.
List of Ingredients

Stacker 2 claims to be “The World’s Strongest Fat Burner”. The formula, called a “Proprietary Blend”, is designed to increase your metabolism and therefore your body heat. This stimulates your brain and raises your heart rate. White willow bark is essentially aspirin and the caffeine completes the stack. In addition to weight loss, benefits claimed are a decrease in appetite and an increase in energy.

Stacker 2 has a few quality positive weight loss ingredients combined with ingredients that are not likely to do anything at all. It is assumed that the Proprietary Blend is greater than the sum of its parts. There is no evidence whatsoever to support that claim. It’s impossible to measure the potency of the product or determine if there is enough of the ingredients to be effective. If you have had success with traditional “stack” products in the past, you will be disappointed with Stacker 2.
