Our read on Liberty Peptides
7 of Liberty Peptides' 19 graded samples passed (37%), and 32% of all samples were sent in by buyers rather than by the shop.
Results are improving: 67% passed over the latest six months, up from 23% before.
When a sample failed, the most common reason was purity under 99.5% (9 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, Liberty Peptides' pass rate is at or above 7% of them, and it has more tests on record than 49% of them.
