Here's an article I just found. Should be interesting to find out what company's are putting the sauce in their supplements.

USADA to name and shame contaminated supplements
By Shane Starling in Secaucus, New Jersey, 27-Apr-2010



The US Anti-Doping Agency (USADA) has been methodically buying dietary supplements from vendors and websites like amazon.com and will produce a list of branded products that contain banned substances by the end of the summer.

Speaking at the SupplySideEast trade show in Secaucus, New Jersey, the USADA’s Amy Eichner, PhD, said supplements that advertise prohibited substances, or ingredients that converted to prohibited substances, could find themselves on the list. Steroid and stimulant contamination are the most obvious targets.

Empowerment


“We want to empower athletes,” Eicher said, noting it was also advising athletes that chose to take supplements to look for third party, good manufacturing practise (GMP) certificates.

She said ingredients such as methylhexnamine, betel nut and nandoline had flared on its radar of late.

However its position remains somewhat quizzical as it continues to state that it cannot advise athletes on dietary supplements, due to uncertainty over contamination. The current advice to athletes is given on a “if you must take them” basis.

Industry has criticized USADA for not doing enough to bring sporting groups it has formed official alliances with such as the NFL, NBA, MLB, US Olympic Committee (USOC) into line with its own anti-drug protocols.

Industry believes stricter drug-testing may make it more difficult for athletes to blame dietary supplements if they are one of the unlucky that are found to be in breach USADA testing.

It is for this reason many in industry are of the view that new laws such as those proposed and now modified by Republican Senator John McCain, and backed by USADA and the sporting bodies, are so much wasted energies because the existing DSHEA (Dietary Supplements and Health Education Act) already guards against transgressions such as the introduction of steroids.
