Three listings are sold under coded names, and they rest on three different kinds of evidence, which the page keeps separate rather than blending. RIVN-1SG is semaglutide on the vendor's own product title, “GLP-1-SEMA Research Peptide”. RIVN-2TZ and RIVN-2TRZ are tirzepatide on the TZ and TRZ abbreviations carried in the codes, with RIVN-2TZ's own certificate (lot TR30-7436) behind it. RIVN-3RT is retatrutide on a certificate: lot Rt60-1599, search code Rivn2609010630, whose Product field reads “Retatrutide 60mg” at 99.94%. The RIVN-3RT product page links a Retatrutide certificate for each size it sells — 10mg, 20mg, 30mg and 60mg — and the store's second listing for the same product is titled “GLP-3- RETA”. The vendor also confirmed it directly to Prof. Peptide, which is now corroboration rather than the basis.
Struck-through prices are Rivn Peptides’ list price; the bold figure is your price once you apply code PROFPEPTIDE15 at checkout. Prices current as of October 16, 2026.
Testing: Labs & Certificates of Analysis
Rivn publishes a public certificate library that needs no account and no request, and every report in it is issued by Freedom Diagnostics. Prof. Peptide states no size for that library, and the reason is worth giving: the page's own heading, the number of certificate files it serves and an earlier count disagree with one another. A count is a fact about what was observed, and there is no figure here Prof. Peptide can stand behind.
What can be stated is the verification. Six certificates were checked against Freedom Diagnostics' own lookup on 29 and 30 September 2026, with the lookup first shown to return no match for a made-up code, so a pass means something: Retatrutide 60mg (lot Rt60-1599, search code Rivn2609010630), Tirzepatide 60mg (TR60-7311, Rivn2609010610), MOTS-C 40mg (MS40-4327, Rivn2609010638), NAD+ 1000mg (Nad1000-57, Rivn2609010642), Thymosin Alpha-1 10mg (TA10-394, Rivn2609010606) and B12 10ml (B12-373, Rivn2609010598). Each resolved at the laboratory to the report the vendor publishes. Those are the certificates' own reported results, not Prof. Peptide measurements.

Additional tests
PassedReported on the certificates outside that panel.
- Passed: Elemental Impurities (ICP-MS) — Pass — Arsenic, Cadmium, Lead, and Mercury below reporting/specification limitsReported on Thymosin Alpha-1 10mg (lot TA10-394), NAD+ 1000mg (lot Nad1000-57) only.
- Passed: Endotoxin Replicate 1 — Pass (limit Assay Sensitivity: ≤0.05 EU/mL)Reported on Thymosin Alpha-1 10mg (lot TA10-394), NAD+ 1000mg (lot Nad1000-57) only.
- Passed: Endotoxin Replicate 2 — Pass (limit Assay Sensitivity: ≤0.05 EU/mL)Reported on Thymosin Alpha-1 10mg (lot TA10-394), NAD+ 1000mg (lot Nad1000-57) only.
- No specification printed: Microbial Analysis (PCR) — No Detectable Microbial DNAReported on Thymosin Alpha-1 10mg (lot TA10-394), NAD+ 1000mg (lot Nad1000-57) only.
One limit belongs beside that, and it is the kind a reader cannot see from a single report: the panels vary by batch. Endotoxin (LAL), sterility (PCR) and heavy metals (ICP-MS) appear on the MOTS-C, NAD+ and Thymosin Alpha-1 certificates and on the 3RT report, while a Semaglutide lot records those same panels as “Not reported”. So full-panel testing is not a catalog-wide property here, and this page does not claim it is. No accreditation is printed on the certificates, so none is claimed.
Payment and shipping
The homepage shows payment icons for Apple Pay, Google Pay, Mastercard, American Express and Visa. Orders ship from 710 Nashville Pike Ste 104, Gallatin, Tennessee. The site banner states that shipping is same-day and free. The shipping policy it links to names no carrier and no order cutoff, states that orders ship during business days only with no weekend or holiday dispatch, and says that shipping options, costs and delivery estimates may vary by destination and carrier. Shipping fees, it adds, are “calculated at checkout unless otherwise stated”.
There is no conventional returns policy. What the vendor offers instead is Shipping Protection, which it describes as free and which covers a lost or damaged shipment: a claim must be filed within two days of the estimated delivery date, or two days of the marked delivery date where a package shows as delivered but was not received, and an approved claim is resolved by a free reshipment or store credit of equal value, at the vendor's discretion. Its exclusions list names, among others, orders sent to freight forwarders or to “international destinations, if applicable”.
Customer service
Rivn lists the email help@RivnResearch.com, the telephone number 615-866-6338 and a contact form, with hours given as Monday to Friday, 9:00AM–5:00PM CST. The heading above the phone number reads “Chat support”, but the channel it offers is text messaging rather than a live-chat window, and no chat widget was found on the site. Rivn states that the people answering are an in-house team.
