Another Reminder to be careful with supplements

UKA's  anit-doping educator David Walsh   flatly stated: “With supplements you can’t give 100% guarantees"   David was talking about the risks of tainted supplements.  In the USm you should check to make sure your supplements are NSF Safe certified.   NSF independently tests the supplements to be sure that they contain what they say they contain and nothing more.      I've written a little more extensively about there at Cycling illustrated.   Check it out.
