Our read on XTP
9 of XTP's 18 graded samples passed (50%), and 100% of all samples were sent in by buyers rather than by the shop.
Results are slipping: 43% passed over the latest six months, down from 75% before.
When a sample failed, the most common reason was purity under 99.5% (9 times).
Against the 302 shops with at least five graded tests, XTP's pass rate is at or above 17% of them, and it has more tests on record than 45% of them.
When and how XTP was tested
