According to customer reviews, there is some veracity to Stimerex's claims as a weight loss enhancer. Stimerex cautions that the product is most effective when combined with an exercise plan.
The active ingredients in Stimerex are ephedra and phenethylamine, both of which of which are demonstrated metabolism boosters. Ephedra was banned by the FDA in 1994, and Consumer Reports warns that the ephedra extracts marketed by weight loss drug manufacturers as of 2012 have little or no effect on weight loss. Phenethlyamine, on the other hand, is known to be a metabolism booster used to aid in weight loss. This means that Stimerex is likely to help achieve weight loss goals along with proper diet and exercise, but on its own, it does not produce significant weight loss.
