VENDOR AUDIT

Limitless Biotech

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.
