How they compare: the verdict

Luv Aminos takes this matchup by a razor-thin margin, 7.90 to 7.68 on the published formula. Its biggest edge is pricing, where it scores 9.5 against Loti Labs's 6.4.

It isn't a clean sweep. Loti Labs actually edges ahead on operating history (7.2 vs 1.1), so if that factor matters most to you it's worth weighing.

On lab evidence, the heaviest-weighted factor, both Loti Labs and Luv Aminos have independently verified third-party COAs, so the gap comes down to the other categories.

Across the 11 peptides both carry, Luv Aminos is cheaper per unit more often (Loti Labs wins on 0, Luv Aminos on 11). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
