Our read on Mia Peptide
8 of Mia Peptide's 10 graded samples passed (80%), and 100% of all samples were sent in by buyers rather than by the shop.
When a sample failed, the most common reason was purity under 99.5% (1 time).
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, Mia Peptide's pass rate is at or above 66% of them, and it has more tests on record than 31% of them.
