Amphetamines for vitamins

Some leading vitamin stores have taken a supplement off their shelves this week. These supplements held a stimulant in them called BMPEA. The chemical has been studied back in the 1930's and was shown to be closely related to amphetamines. In December of last year Canadian health authorities pulled these supplements off the shelves. With the supplement having the chance to cause stroke, and other serious cardiovascular complications. The FDA in 2013 found the BMPEA ingredient found in several weight loss and workout supplements. However they did not name them.
