Adherence

Collegiate student-athletes have low knowledge of nutritional supplements and third-party-tested (TPT) logos, and this lack of recognition does not correlate with their actual use of TPT supplements.

If you are a collegiate athlete, do not assume that recognizing a third-party testing logo means you are using safe supplements. The study shows that knowing the logo does not predict whether you actually use TPT products. Your overall knowledge of supplements is likely lower than you think (median 33% correct). To mitigate doping risk, do not rely on logos alone. Verify every specific product batch on the testing organization's official website, regardless of whether you received nutritional counseling from your athletic department.
