Direct answer

Is RNX Research legit?

RNX Research earns 8/10 overall with all 18 report sets independently verified against official BT Labs, ILS Laboratories and Kovera Labs records. We retained 32 analytical pages, including the full two-page files for all 12 BT reports; 15 current exact product strengths have verified listing evidence, with three older batches retained separately. Six BT reports record more peptide content than their printed 90–110% range permits, including one historical MOTS-c report. These findings remain visible alongside the 8/10 COA score. The Trustpilot profile showed 4.7/5 from 37 entries on October 7, 2026. Free US ground shipping, free two-day shipping above $125 and a confirmed 10% code support its 9/10 operations score.

Evidence summary

RNX Research COAs and evidence

RNX combines 18 independently verified report sets, positive customer feedback and clear US delivery terms. The complete archive covers 15 current exact product strengths and retains three historical batches. Six BT peptide-content results exceed their own 90–110% specification; those findings remain visible even though the reports match the laboratory originals.

01

A complete archive across three laboratories

RNX’s certificate archive publishes 18 distinct issued report sets: 12 two-page BT Labs reports, four ILS Laboratories reports and two Kovera Labs reports. All 18 sets independently match their official laboratory records. We retained all 32 analytical pages, covering 15 current exact product strengths and three historical batches. Three BT sets are older batches of GLP-3R, GLP-2T and MOTS-c for which newer reports are also available. NAD+ is marked as still in analysis and has no issued certificate. Every issued set reports identity, HPLC purity and measured peptide content; these are distinct checks of what the sample is, how pure it is and how much peptide it contains.

02

What the verified ILS and Kovera reports show

Four ILS reports cover GLP-3R 10 mg, GLP-2T 30 mg, 5-Amino-1MQ 5 mg and SS-31 10 mg. We compared their client, compound, amount, lot, report details and analytical results with the official ILS portal. The reports include a fentanyl screen as well as identity, purity and measured content. Kovera’s verified KPV 10 mg and MOTS-c 10 mg sets also contain rapid sterility pages missing from the merchant’s one-page downloads. Those two-day screens at 30–35°C show no bacterial growth and no detected fungi or yeast. A rapid screen has a narrower scope than a compendial sterility test; its result should be read with that method in view.

03

All 12 BT reports independently matched

All 12 BT reports match the complete two-page files independently obtained from BT’s official verification site. We compared the RNXResearch client name, compound, labeled strength, lot, sample identifiers, report details and actual analytical results. Every field matches the corresponding vendor file, including the second-page chromatograms. The BT panel has three distinct checks: identity, HPLC purity and measured peptide content. Their matching out-of-range potency values are authentic laboratory findings, so verification does not turn those results into a pass.

04

Six peptide-content results above the stated range

The printed BT potency results exceed the stated 90–110% range for BPC-157 (118.5%), TB-500 (111%), the older MOTS-c lot (124.8%), Tesamorelin (127.2%), Selank (121.9%) and Melanotan-2 (126.6%). These samples contain more measured peptide than the report’s specification allows. Their high purity results do not remove that quantity discrepancy: purity and vial content measure different things. The other six BT potency values are within the printed range. The full certificates show the nominal amount, measured amount and specification together, including the chromatograms on the second pages.

05

Customer reviews and their limits

Trustpilot displayed 4.7/5 from 37 entries when reviewed October 7, 2026. All captured entries were five-star reviews, with recurring descriptions of quick delivery, careful packaging and direct help from Rocco. Delilah Lessor wrote “Great prices and excellent turnaround time.” Maria Troche wrote “Fast shipping love this company.” The observed set includes repeated submissions; Trustpilot counts only each reviewer’s latest review toward its TrustScore. The claimed profile invites reviews and covers a short 2026 trading history. This customer evidence supports our 8/10 reputation score.

06

Legal identity and batch transparency

The storefront identifies RNXRESEARCH LLC and lists 2389 Main St, Glastonbury, Connecticut 06033 as its mailing address. Verisign’s domain record gives April 2, 2026 as the registration date. The About page describes one person overseeing orders, batches, certificates and support, and claims testing before each lot is sold. Public certificates identify the client and print lot numbers, giving buyers a practical batch reference to check against a received vial. We have not established the mailing address as a laboratory or manufacturing site, or matched a shipped customer vial to a listed lot. We rate transparency 8/10.

07

Dispatch, delivery and payment

The shipping policy offers free ground delivery on every US order and free two-day shipping above $125. It covers all 50 states, US territories and eligible USPS PO/APO/FPO addresses; international delivery is not currently offered. RNX states same-day dispatch before 3 PM Eastern Monday–Friday and 10 AM Eastern Saturday. Orders travel with USPS or UPS tracking in plain packaging, and the first carrier scan may take up to 24 hours. Google Pay, Apple Pay, Link, credit/debit cards, Venmo, Zelle and cryptocurrency were confirmed on October 7, 2026. These payment choices and delivery terms support our operations score of 9/10.

08

Returns and the confirmed coupon

The refund and return policy provides a replacement for a damaged or incorrect item when photographs are supplied within 72 hours of delivery. Shipped research materials cannot be returned or exchanged; confirmed-delivered parcels are not refunded or replaced if later missing.
