Our read on Shandong Shengyuan Peptide Technology
25 of Shandong Shengyuan Peptide Technology's 33 graded samples passed (76%), 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 81% before.
When a sample failed, the most common reason was purity under 99.5% (4 times).
2 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, Shandong Shengyuan Peptide Technology's pass rate is at or above 63% of them, and it has more tests on record than 66% of them.
