Our read on Welon Peptide Solutions
31 of Welon Peptide Solutions' 51 graded samples passed (61%), and 96% of all samples were sent in by buyers rather than by the shop.
Results are slipping: 56% passed over the latest six months, down from 80% before.
When a sample failed, the most common reason was purity under 99.5% (12 times).
5 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, Welon Peptide Solutions' pass rate is at or above 26% of them, and it has more tests on record than 80% of them.
