Two audits, side by side. Composite, subscores, shipping, payment, coupons. Ion Peptide takes the higher composite this cycle.
US research-peptide vendor with the cleanest COA paper trail in our public-data cohort - 120 Kovera Labs reports across two months at a median 99.93% purity, zero failures, zero identity-mismatch. Coded ION-X SKU naming on a subset of products is worth knowing about.
Limitless Biotech (formerly Limitless Life Nootropics) is the rebranded US vendor at limitlessbiotech.com. Our April 2026 test order returned 96%+ retatrutide purity with clean cross-lab agreement and 2-day US shipping at premium prices. Buyers should weigh that against a pseudonymous owner-of-record, a promo-seeded Trustpilot base, and community scam reports that predate the rebrand.
