How they compare: the verdict
Loti Labs takes this matchup by a razor-thin margin, 7.68 to 7.55 on the published formula. Its biggest edge is operating history, where it scores 7.2 against Ascension Peptides's 4.1.
It isn't a clean sweep. Ascension Peptides actually edges ahead on lab credibility (9.1 vs 8.2), so if that factor matters most to you it's worth weighing.
On lab evidence, the heaviest-weighted factor, both Ascension Peptides and Loti Labs have independently verified third-party COAs, so the gap comes down to the other categories.
Across the 14 peptides both carry, pricing is evenly split (Ascension Peptides 7, Loti Labs 7). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
