Our read on HKPep
5 of HKPep's 6 graded samples passed (83%), and 100% of all samples were sent in by buyers rather than by the shop.
When a sample failed, the most common reason was the lab could not confirm it was the labelled peptide (1 time).
Against the 302 shops with at least five graded tests, HKPep's pass rate is at or above 77% of them, and it has more tests on record than 9% of them.
