Testing & Certifications Explained

USN products carry the Informed Choice certification.

While this certification is valuable for athletes, it does not verify the accuracy of the supplement facts label or the purity of the ingredients beyond banned substances. Consumers looking for broader assurance should seek out third-party tested supplements with certifications like NSF Certified for Sport or USP.

Consumers should compare USN reviews and testing information with those of competitors to make informed decisions.

Buying Guidance

If considering USN products, look for the Informed Choice logo on the product packaging.
