ANSWER:
Not all supplements are safe for use in the sports arena due to the proven contamination of sports supplements which contain banned and/or illegal substances.

Neither the NCAA nor WADA have recommendations regarding which supplements are safe for use.

They do, however, list banned and illegal substances, ingredients and procedures.

L-Arginine is not banned and is not on the NCAA or WADA banned substance list.

Any L-Arginine supplement Approved by Human Sport Performance® (HSP) (www.HumanSportsPerformance.com) meets and/or exceeds any qualifications set by the World Anti-Doping Agency and is safe for use in any sport by athletes over the age of 23.
