Supplement drugs to perform better....

Do you know GNC stores?
They sell products to help customers to loose weight, to perform better on a sport game, to gain muscles. It seems like magic. But sometimes it ends up quite badly... You hear about young people who died because the coktail of stumulants inside the drug raise blood pressure, raise the heart rate and so on

. And the FDA doesn't regulate this market that much. You can be tested positive by an anti-doping agency if you do some competition sports even though you purchased your drug very easily.
