How they compare: the verdict
Loti Labs takes this matchup by a razor-thin margin, 7.68 to 7.67 on the published formula. Its biggest edge is operating history, where it scores 7.2 against Protide Health's 3.0.
It isn't a clean sweep. Protide Health actually edges ahead on transparency (6.0 vs 3.0), so if that factor matters most to you it's worth weighing.
On lab evidence, the heaviest-weighted factor, both Loti Labs and Protide Health have independently verified third-party COAs, so the gap comes down to the other categories.
Across the 18 peptides both carry, Protide Health is cheaper per unit more often (Loti Labs wins on 7, Protide Health on 11). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
