Our read on BFF Chem
6 of BFF Chem's 7 graded samples passed (86%), and 100% of all samples were sent in by buyers rather than by the shop.
When a sample failed, the most common reason was the lab could not confirm it was the labelled peptide (1 time).
Against the 302 shops with at least five graded tests, BFF Chem's pass rate is at or above 82% of them, and it has more tests on record than 17% of them.
When and how BFF Chem was tested

- Labs used
- Krause Analytical (3), BTLabs (3), Harrens Lab (1)
