Our read on Uther
73 of Uther's 97 graded samples passed (75%), and 80% of all samples were sent in by buyers rather than by the shop.
The pass rate has held steady: 78% over the latest six months against 74% before.
When a sample failed, the most common reason was purity under 99.5% (14 times).
4 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, Uther's pass rate is at or above 62% of them, and it has more tests on record than 91% of them.
When and how Uther was tested
Samples per month. The darker part of each bar failed.
