Red bull, the little can so frequently seen in gear bins and race transition areas, has become the
first company to have a product certified as "OK to consume and not test positive for banned substances"; it's a new program the government has implemented. From the previous link:
"Certification Addresses Athletes' Fear of Unknowingly Testing
Positive For Banned Substances and Desire for Higher Quality
Supplements and Nutritional Products"
So, drink your Red Bull in good conscience. There has never been much talk of drug testing in AR (but
Recover-Ease
and some other supplements might push the envelope, but everyone
maintains the stuff is free of banned substances), but I know lots of
people swear by a Red Bull every now and then!
