Never merged into one number. Some supplier links here are referral links, marked where they appear, which pay Terminus Research when a reader buys. The same terms are open to every supplier in the ledger, apart from the one exception the referral policy page names, participation changes no score, rank, caution, or coverage decision, and a link is not an endorsement.
VAYN's own retatrutide product page points its "View Certificate of Analysis (COA)" link not at vayn.co's working /coas index but at https://his-and-hers.com/coas, a different company's domain the site never explains, and the connection turns out to matter: the newest of four listed retatrutide 10mg batches, the only one to add endotoxin and sterility lines, documents its purity and identity through a Freedom Diagnostics certificate issued to a client named His & Hers, photographing a vial printed HIS & HERS RETATRUTIDE 10MG, while the only VAYN-client document for that lot covers endotoxin and microbial screening alone. The three older batches instead cite a lab called Chromate, whose homepage makes no accreditation claim and whose verification link renders nothing without client-side script. VAYN's refund policy also runs close to word-for-word the same as uschemlabs.com's, despite the two sites naming unrelated legal entities and unrelated testing labs. A reader who received the current RETA10-A4 batch could say whether the vial itself was labeled VAYN or His & Hers.
What the record holds
NO FIRM COMMITMENT
“UPS live rates ranging from Ground to Next Day, free above a $250 cart subtotal”
The Ground-to-Next-Day range is a carrier service menu priced at checkout, not a dispatch commitment of the vendor’s own, and no page read states a handling time or cutoff, so under the weaker-when-ambiguous rule the class is no firm dispatch commitment. The same entry records the optional ParcelGuard Protection add-on at roughly one percent of the order total, covering loss, theft and damage in transit, which the FAQ states VAYN will not otherwise reimburse if the option is declined.

This supplier was not part of the Trustpilot reading of 2026-08-25, which covered 59 of the 126 suppliers on file. That is a fact about this publication's coverage, stated rather than left to be read either way.
5 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-26: 1 held, 4 corrected before publication.
A corrected claim is an error of ours that the re-read caught before it reached a page. This line tracks this publication's own accuracy. It says nothing about the supplier.

VAYN publishes a genuine per-batch certificate index at /coas, listing eighty-eight distinct batch-code links today under the heading "At VAYN, purity and quality of our products is our top priority. All of our products have a COA (Certificate of Analysis) per batch listed below," each code its own page at /coas//. Retatrutide 10mg carries four listed batches: RETA10-A3 (packaged 2025-11-24, tested 2025-12-04, 9.929mg measured, purity 99.887 percent, cap green), RETA10-G27B1 (packaged 2025-07-14, tested 2025-07-25, 10.24mg, purity 99.809 percent), RETA10-G27C1 (packaged 2025-09-04, tested 2025-09-05, 11.64mg, purity 99.558 percent, cap yellow), and RETA10-A4, the newest, tested 2026-04-14, 12.65mg, purity 99.897 percent, and the only one of the four to add an Endotoxin line, reporting no endotoxin detected and marked as a pass, and a Sterility line, reporting no microbial DNA detected and also marked pass. The three older batches each link out to a laboratory verification URL of the form chromate.org/verify?c=; the newest batch, RETA10-A4, the one carrying the two added lines, carries no chromate.org link, but its Certificate of Analysis field is not empty: it embeds two certificate images from a different laboratory, Freedom Diagnostics (FreedomDiagnosticsTesting.com), both read directly today. The first, accession 2604130183, received 04/13/2026 and reported 04/14/2026, is the purity and identity document, Retatrutide 10mg at 99.90 percent by HPLC-UV with identity confirmed by LC-MS and net content 12.65 mg, but its client field reads His & Hers, not VAYN, and its sample photo shows a vial printed HIS & HERS RETATRUTIDE 10MG. The second, accession 2607210165, received 07/21/2026 and reported 07/24/2026 against lot RETA10-A4, is the only VAYN-client document for the batch and covers endotoxin (LAL under USP <85>, two replicates, both Pass) and a microbial PCR screen (Pass), with no purity or identity figure of its own. Separately, the retatrutide product page itself (/shop/research-peptides/metabolic-research/retatrutide/) embeds its own "View Certificate of Analysis (COA)" link in the product description twice, and that link points not to vayn.co's own /coas but to https://his-and-hers.com/coas, a different company's domain never explained on any page read; the His & Hers client name on RETA10-A4's own purity certificate gives that link a connection the site itself never states.
The laboratory named on three of the four retatrutide batch pages, Chromate, is independently locatable at chromate.org, a live site fetched today, self-described on its About page as founded to make supplement analysis accessible to all in order to protect the fitness and supplement-using community and keep manufacturers honest, with a stated background in doping-substance and supplement-contamination testing rather than research-peptide testing specifically, though its Services page gives explicit sample-prep instructions for "Peptide Vials": "At least 1 vial is needed for HPLC analysis. Additional vial(s) are needed for microbiology tests." Its Contact page gives a location, "Hudson, NH 03051," and a phone field that read "Offline" rather than a number at the time of this read. No accreditation is claimed on the site; ISO 17025, A2LA and CLIA return no hits. The /verify?c= route itself could not be read past its own gate: every load, including the RETA10-A3 batch's job 30074, returned the same "javascript must be enabled to access database" notice to the fetch, so the underlying chromatogram or identity finding behind each verification code was not something this pass could confirm; what is confirmed is that the code resolves to a live, uniquely numbered job page on the laboratory's own domain rather than to a dead link. The fourth, current batch, RETA10-A4, is documented instead by a second, unrelated laboratory, Freedom Diagnostics, through the two certificate images described in the entry above, so this product's batches split across two labs with no page explaining the change.
Benchmark and catalogue read from the live WooCommerce store data on 2026-08-26; prices in US dollars. Retatrutide 10mg (variation ID 295, SKU reta-10) is a single vial at $80.00, with 20mg, 30mg and 60mg single-vial sizes at $145.00, $220.00 and $350.00 in the same variation block; a sitewide banner at the time of the read advertised a site-wide 50 percent discount at checkout with the code BTS50 through August 31st, a checkout-code discount not reflected in the $80.00 listed variation price itself. The shop groups roughly thirty named peptide products under six research categories: Metabolic Research, Growth and Endocrine Research, Aesthetic and Dermal Research, Neuro and Cognitive Research, Longevity and Cellular Research, and Reproductive and Behavioral Research, plus a Supplies section for bacteriostatic and acetic-acid water and a small merchandise line. Payment, per /faq/: all major credit cards, named as Visa, Mastercard, Discover and Amex, plus Apple Pay, Google Pay, and PayPal, which the FAQ states supports Pay Over Time and Crypto payment. Shipping is by UPS live rates ranging from Ground to Next Day, free above a $250 cart subtotal, with an optional add-on named ParcelGuard Protection, described as a small fee of roughly one percent of the order total, covering loss, theft and damage in transit, which the FAQ states VAYN will not otherwise reimburse if the option is declined. Refunds, per /refund-policy/, require a claim within 7 days of delivery with photographic evidence for damaged or defective items; opened packages are excluded. The legal entity is named in the footer as "VAYN Research, LLC," with a "Veteran Owned and Operated in USA" badge repeated on every page read; contact is a phone number, +1 833-S00-VAYN (+18337008296), and an email address behind Cloudflare obfuscation, with no street address on the Contact page itself. The age gate reads a consistent 21-plus across the homepage modal, the FAQ and the Terms and Conditions page.
CAUTIONCautions noted. First, the retatrutide product page's own "View Certificate of Analysis (COA)" link, appearing twice in the product description, points to https://his-and-hers.com/coas rather than to vayn.co's own working /coas index; His and Hers is not named as a VAYN brand or affiliate anywhere else on the site read, so the link reads as unedited copy carried over from a different vendor's page template rather than an intentional cross-reference. Second, VAYN's own COA index carries a working Chromate laboratory link for three of the four retatrutide 10mg batches, but the fourth, RETA10-A4, the newest by test date and the only one of the four to report Endotoxin and Sterility screening beyond HPLC purity, is documented instead by two Freedom Diagnostics certificate images embedded on its own batch page, and reading them shows the purity and identity figures for the batch come from a certificate issued to a different named client, His & Hers, photographing a vial printed with that other brand's name, while the only VAYN-client document for the same lot covers endotoxin and microbial screening alone; the purity figure a shopper reads on VAYN's most thoroughly documented batch was never run against a VAYN-labelled vial. Third, the refund-policy text at /refund-policy/ is close to word-for-word the same boilerplate found on uschemlabs.com's FAQ return-policy section during the same pass: both open with a near-identical sentence about rigorous quality-control standards and the fragile nature of the products, both use "Perishable Products" as the section head, and both set the same 7-day, photographic-evidence claim window, despite the two sites naming unrelated legal entities, VAYN Research, LLC against US Chem Labs, Inc., and unrelated testing laboratories, Chromate against Atomic Echo. The shared wording suggests a common storefront template rather than independently drafted policy. Fourth, the laboratory verification links that do resolve lead to a page that requires client-side script to render any content, so the purity and identity figures printed on VAYN's own /coas pages are, for the three batches carrying a link, corroborated only by the existence of a live, uniquely numbered job page on the laboratory's own domain, not by a document this pass could read start to finish.
