Our read on SRY Labs
86 of SRY Labs' 131 graded samples passed (66%), and 95% of all samples were sent in by buyers rather than by the shop.
Results are improving: 82% passed over the latest six months, up from 64% before.
When a sample failed, the most common reason was purity under 99.5% (36 times).
3 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, SRY Labs' pass rate is at or above 32% of them, and it has more tests on record than 93% of them.
