Two audits, side by side. Composite, subscores, shipping, payment, coupons. Limitless Biotech takes the higher composite this cycle.
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.
Operator received an FDA warning letter on December 10, 2024 as "Summit Research Peptides," then rebranded to Summit Biotech without disclosing the prior identity on the new site. Login-walled catalog, code-name SKUs for the FDA-cited compounds, and the cheapest per-mg pricing in our seven-vendor index on Tirzepatide, Retatrutide, and Semaglutide. ~90% of COAs are real Janoshik public-database links.
