106 of TSC Top Supplements China's 146 graded samples passed (73%), and 100% of all samples were sent in by buyers rather than by the shop.
Results are improving: 79% passed over the latest six months, up from 71% before.
When a sample failed, the most common reason was purity under 99.5% (34 times).
4 samples failed identity, meaning the lab could not confirm the vial held the labelled peptide.
Against the 302 shops with at least five graded tests, TSC Top Supplements China's pass rate is at or above 51% of them, and it has more tests on record than 95% of them.
