Our read on Biolongevity Labs
25 of Biolongevity Labs' 34 graded samples passed (74%), and 12% of all samples were sent in by buyers rather than by the shop.

Against the 302 shops with at least five graded tests, Biolongevity Labs' pass rate is at or above 54% of them, and it has more tests on record than 67% of them.
