Our read on Super Peptides
25 of Super Peptides' 34 graded samples passed (74%), and 100% of all samples were sent in by buyers rather than by the shop.
Results are improving: 77% passed over the latest six months, up from 71% before.
When a sample failed, the most common reason was the lab could not confirm it was the labelled peptide (6 times).
Against the 302 shops with at least five graded tests, Super Peptides' pass rate is at or above 54% of them, and it has more tests on record than 67% of them.
