Our read on ZZQ Peptides
35 of ZZQ Peptides' 51 graded samples passed (69%), and 100% of all samples were sent in by buyers rather than by the shop.
Results are improving: 85% passed over the latest six months, up from 63% before.
When a sample failed, the most common reason was purity under 99.5% (13 times).
1 sample failed identity, meaning the lab could not confirm the vial held the labelled peptide.
Against the 302 shops with at least five graded tests, ZZQ Peptides' pass rate is at or above 42% of them, and it has more tests on record than 80% of them.
