Overview
Reta One Labs (retaonelabs.com) is a US research-peptide supplier.

Prof. Peptide states no entity type and no founding date for it: a Texas Comptroller search on 30 September 2026 returned no registered entity under either spelling, and the vendor publishes neither.

Testing: Labs & Certificates of Analysis
Reta One Labs' public COA library states “Showing 71 of 71” test results, drawn from three labs across fourteen months — Chromate (11 certificates, July–September 2025), Vanguard Laboratory (25, September 2025–May 2026) and the current lab, Kovera Labs (35, May–September 2026). Prof. Peptide counted the 71 entries directly from the library's own data rather than trusting the header figure alone, and the two agree. Every current-era certificate carries a seven-item panel — net purity, net content, identity, endotoxins, sterility, heavy metals, conformity — and links to Kovera's own verification portal. The Vanguard-era certificates (25 of 71) carry only purity and net content, without the identity, endotoxin, sterility or heavy-metals fields the Chromate and Kovera eras both show.
On 2026-09-29, Prof. Peptide checked a sample of 5 current Kovera Labs certificates against the laboratory's own verification portal (koveralabs.com/verify), using the report code printed on each certificate. All 5 matched Kovera's own record: CJC-1295 (No DAC)/Ipamorelin (batch CJIP200826, code KVR-2026-036FAB), GHK-Cu (GK500826, KVR-2026-0AFB90), RO-3RT — Retatrutide — (RT120826, KVR-2026-604D6F), Tesamorelin (TS100526, KVR-2026-2CBF9B) and MOTS-c (MTS100626, KVR-2026-7DA118). That 5 is a sample Prof. Peptide observed, not a count Reta One Labs publishes — the remaining 30 Kovera-era certificates, and all 36 certificates from the two earlier labs, were not individually re-checked at a lab portal this pass. On 14 October 2026 Prof. Peptide drew three certificates at random from the whole library: the Semax and PT-141 reports were found at Kovera's own lookup, and the Vanguard Laboratory retatrutide 60mg report was not found in Vanguard's public report store under the vendor's name.

Not found at the lab
Not foundRetatrutide 60mg, lot R601025 (Vanguard Laboratory V251029-12 004): Vanguard’s public report store lists no reports for the brand “Reta One Labs”, “Reta One” or “RetaOne Labs” (checked 14 October 2026).
Payment and shipping
The payment methods shown in the site footer are Visa, Discover, Zelle, bank transfer and cryptocurrency. On carriers the vendor is deliberately loose, writing that it “will typically ship through carriers like UPS and Fedex” and asking for a physical address rather than a PO box or military address. Domestic orders typically ship within 24–48 hours and arrive in 2–5 business days; international orders may take 7–14 business days through customs. An order can be cancelled or modified within two hours of placement, and not after.
Returns are not accepted once a product has shipped. In their place the vendor offers what it calls a 100% Quality Satisfaction Guarantee: on independent laboratory analysis showing a product does not meet its stated specification, submitted within 30 days of delivery with the order number, batch number and the lab report, it states it will provide a full refund plus replacement. That is the vendor's undertaking, reported here rather than tested.
Customer service
Reta One Labs lists a contact form, the email support@retaonelabs.com and a telephone number, 866-932-0050. No live chat is offered and no support hours are published. The contact page asks customers to “allow 48 business hours for a reply”, which is the vendor's own statement of pace rather than a commitment Prof. Peptide has measured.
Online reviews
Prof. Peptide checked Trustpilot and Finnrick on 30 September 2026. Trustpilot: 3.3 from 13 reviews (read 30 September 2026).
