Our read on TP Peptide
5 of TP Peptide's 6 graded samples passed (83%), and 100% of all samples were sent in by buyers rather than by the shop.
Results are slipping: 67% passed over the latest six months, down from 100% before.
When a sample failed, the most common reason was purity under 99.5% (1 time).
Against the 302 shops with at least five graded tests, TP Peptide's pass rate is at or above 78% of them, and it has more tests on record than 9% of them.
