About Reta One Labs
A roughly 1-year-old US (Cypress, TX) GLP-class research-peptide shop that actually publishes a real per-batch COA library across three named third-party labs (Kovera, Vanguard, Chromate); two certificates were personally opened and confirmed (BPC-157 >99.8% ISO-17025 Vanguard, Retatrutide 99.302% Chromate), both naming Reta One Labs. Competitive transparent pricing and fast tracked UPS cold-chain shipping, but reputation is thin and mixed (Trustpilot 3.4/5 from 11 reviews) and no legal entity is named.

Key facts
Pros
- Genuine, published per-batch COA library across THREE named independent labs (Kovera 25, Vanguard 25, Chromate 11); two certs personally opened and tied to this vendor: BPC-157 >99.80% +/-0.18% on ISO/IEC 17025 A2LA-accredited Vanguard (endotoxins+sterility PASS) and Retatrutide 99.302% on Chromate, both with chromatograms, vial photos and verify portals; the library even publishes sub-99% failing results, a rare honesty signal
- Competitive, transparent US-market pricing with vial sizes (Reta 10mg $29, Tirz 10mg $24, Sema 10mg $29, BPC 10mg $39; free shipping over $400), fast tracked UPS Ground/2nd Day/Next Day shipping with ice-pack cold-chain packaging, card+bank+crypto payment (Visa/Discover give chargeback recourse), and a conditional refund-plus-free-replacement quality guarantee
Cons
- Reputation is thin and mixed: Trustpilot only 3.4/5 from 11 reviews (36% 1-star), with a fake-product claim, a warm Reta + bac-water shipment, and a vials-wont-dissolve + no-support-reply complaint alongside the praise; low independent volume and a domain only ~1 year old (created 2025-07-16)
- No named legal entity/LLC/EIN (only the Reta One Labs brand + a Cypress TX suite address and phone), product pages do not one-click-link the matching COA or name the lab (must search the /coa/ library or request by batch number), and pricing leans on heavy sale/discount framing with some quantity over-fills (+11.9%/+24%)
