Our read on LiliPeptide
243 of LiliPeptide's 339 graded samples passed (72%), and 100% of all samples were sent in by buyers rather than by the shop.
The pass rate has held steady: 72% over the latest six months against 71% before.
When a sample failed, the most common reason was purity under 99.5% (72 times).
16 samples failed identity, meaning the lab could not confirm the vial held the labelled peptide.
Against the 302 shops with at least five graded tests, LiliPeptide's pass rate is at or above 50% of them, and it has more tests on record than 99% of them.
