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.
Aggressively priced US-listed catalog with full GLP-1 lineup (Retatrutide, Tirzepatide, Semaglutide), but the "Prime Research Peptides" brand is a hostname alias for Truform Compounds — same server, same WooCommerce instance, same page-title throughout. Editorial finding documented below. Pricing remains the strongest in our index for retatrutide on a per-mg basis; the credibility-relevant question is whether buyers know who they're actually buying from.
No exclusive specialties for Limitless Biotech.
