How they compare: the verdict
BulkGLP takes this matchup decisively, 6.71 to 3.70 on the published formula. Its biggest edge is lab credibility, where it scores 7.9 against BioInfinity's 1.8. BioInfinity also carries the testing gate: Third-party testing not established.
It isn't a clean sweep. BioInfinity actually edges ahead on transparency (6.0 vs 4.5), so if that factor matters most to you it's worth weighing.
On lab evidence, the heaviest-weighted factor, BioInfinity has no third-party testing we could independently verify, while BulkGLP has independently verified third-party COAs.
Across the 7 peptides both carry, BulkGLP is cheaper per unit more often (BioInfinity wins on 0, BulkGLP on 7). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
