Only 0.6% of on-market supplement labels name a USP, NSF or ConsumerLab testing mark
Across 121,959 on-market labels in the 2026-01-16 DSLD dump, 722 name a testing-program mark and 297 a banned-substance sport mark; 3,031 use self-declared wording such as GMP or "third-party tested". Labels only show what they say, and a logo with no words is not captured.
