In an unregulated market, third-party testing is your only guarantee that a supplement contains what’s on the label.
What Testing Actually Tests
Testing verifies identity (is this really creatine monohydrate?), potency (does it contain the claimed amount?), and purity (is it free of heavy metals?).
USP Verified
The United States Pharmacopeia requires strict manufacturing standards. Only about 100 products carry this mark.
NSF Certified for Sport
Critical for competitive athletes, NSF tests for over 270 banned substances. All major sports organizations accept NSF certification.
Informed Sport
UK-based testing focused on prohibited substances. Products are tested every batch. Over 2500 supplements carry Informed Sport certification worldwide.
