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.
Grey Research Peptides publishes retatrutide certificates from Freedom Diagnostics that check out against the lab's own domain, lot 30045 reading 99.82 percent purity by HPLC with UV detection coupled with mass spectrometry, and the vendor's copies matched the lab-hosted PDFs text for text on the three products spot-checked. Coverage stops well short of the badge, though: 13 of 45 catalog products, bacteriostatic water among them, carry no certificate anywhere in the lab's records yet still display the identical badge promising purity of at least 99 percent by HPLC with mass-spectrometry confirmation, while the purity floor itself is stated three different ways across the site, that badge figure, at least 98 percent by HPLC, or at least 95 percent by HPLC, depending which page a shopper lands on. Has anyone ordered one of the 13 uncovered products and asked the vendor directly whether a certificate exists for it?

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.
4 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-25: 0 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.

This vendor was assigned alongside greylabs.xyz on a possible sibling-domain theory, addressed in full in the GreyLabs record elsewhere in this file. Summary here: RDAP for this domain shows registrar GoDaddy.com, LLC, nameservers on AWS Route 53, creation date 2025-05-22; greylabs.xyz's RDAP shows registrar Cloudflare, Inc., Cloudflare nameservers, and a creation date of 2026-05-14, a full year later. This site is WordPress plus WooCommerce (wp-json links, Yoast sitemaps, a WoodMart theme footer credit) taking credit cards and ACH; greylabs.xyz is a small hand-built app taking Bitcoin only. Neither site's markup names or links the other. On what I could load today the two read as separately built, separately hosted stores that both landed on the word Grey, not one operation behind two fronts.
Certificates are delivered per product: the retatrutide-10mg page carries a badge reading purity of at least 99 percent by HPLC with mass-spectrometry confirmation, a 'How we test' link to /quality-and-testing/, and a 'Download COA' pill linking directly to a PDF at /wp-content/uploads/2026/05/Retatrutide-10mg.pdf. I fetched that PDF and read its text layer: a Freedom Diagnostics Certificate of Analysis, client GREY RESEARCH PEPTIDES, accession 2605150104, search code GREY2605150104, received 05/15/2026, reported 05/17/2026, lot 30045, product Retatrutide 10mg, identity confirmed (LC-MS, reads GLP RT), purity 99.82 percent, net content 9.99 mg, appearance white lyophilized powder, method stated on the face as HPLC with UV detection coupled with mass spectrometry (LC-MS), signed by a Principal Chemist with no printed name. No endotoxin or sterility line appears anywhere on the document. I checked coverage against the full 45-product catalog (read from /product-sitemap.xml and confirmed by count against the WooCommerce store API): using the lab's own public lookup for this client (detailed in the lab entry below), I obtained 32 accession numbers and fetched all 32 PDFs directly from the lab's domain. Matched by product name against the 45-item catalog, 32 of 45 products carry a certificate and 13 do not: DSIP 10mg, Tesofensine 500mcg x100ct, Methylene Blue 20mg x100ct, Epithalon 50mg, Adipotide 5mg, Melanotan-II 10mg, SLU-PP-332 250mcg x100ct, 5-Amino-1MQ 50mg x25ct, Thymosin Alpha-1 10mg, TB-500 10mg sold alone (the BPC-157/TB-500 blend does carry one), BAC Water 30ml, P21 5mg, and Vesugen 20mg. I spot-checked five other product pages for the same Download COA pattern: tirzepatide-10mg and ghk-cu-50mg each carry a working COA link (and I confirmed both linked PDFs are byte-identical in text to the matching lab-hosted file, GREY2605210245 and GREY2605210251 respectively); dsip-10mg, thymosin-alpha-1-10mg and bacwater30ml, all outside the 32 covered names, carry no Download COA anchor in the page markup at all; the single string match on each of those pages sits inside a CSS comment, not a rendered element, confirmed again on a live fetch today. The absent link is consistent with the coverage count, but the pages themselves are not: each of the 13 uncovered product pages still renders the identical trust badge asserting purity of at least 99 percent by HPLC with mass-spectrometry confirmation, body copy stating a Certificate of Analysis is available for every batch, and a line that every batch is analyzed by HPLC, and the quality page's own Organization markup asserts every batch is backed by a certificate, so a measured floor and per-batch documentation are asserted on 13 products, bacteriostatic water included, for which the lab holds no document (see the eighth caution below).
On lab verifiability, exercised rather than described. Freedom Diagnostics is the same laboratory already in this ledger for a different, unrelated vendor (Full Scale Peptides); this is a documented fact about shared lab usage, not an inference about ownership. freedomdiagnosticstesting.com resolves live today, restating the same details recorded previously: address 133 Holiday Ct Suite 106, Franklin, TN 37067, operating since 2023, a 2 to 4 day turnaround, and a stated count of 42,000-plus public certificates; the words accreditation, ISO 17025, A2LA and CLIA appear nowhere on its site. Its public lookup, a Cloudflare Worker at coa-list.nameless-credit-789e.workers.dev, returned 32 search codes for the company name Grey Research Peptides, spanning three submission dates: seven codes GREY2605150103 through 109 (05/15/2026), thirteen codes GREY2605210241 through 253 (05/21/2026), and twelve codes GREY2606080729 through 740 (06/08/2026, one code, 735, fetched separately). I fetched every one of the 32 PDFs directly from the lab's own domain, coas.freedomdiagnosticstesting.com, and read each: they cover Semaglutide 10mg and 5mg, Retatrutide 10/15/30mg, Tirzepatide 10/15/30mg, BPC-157 10mg and 5mg, Cagrilintide/Semaglutide 5/5mg, CJC-1295/Ipamorelin 5/5mg, Tesamorelin 10mg and 20mg, BPC-157/TB-500 10/10mg, MOTS-C 10mg and 40mg, GHK-Cu 50mg, Klow and Glow blends, NAD+ 1,000mg and 500mg, Glutathione 1,500mg, Testagen 20mg, Hexarelin 5mg, Vilon 20mg, Pinealon 20mg, Sermorelin 10mg, SS-31 50mg, Ipamorelin 5mg, IGF-1 LR3 1mg and PT-141 10mg, purities ranging 99.00 percent to 99.98 percent. I ran the same two controls recorded for this lab previously: an invented company name returned an empty file list, and an invented accession code returned HTTP 404. I directly diffed the text layer of the vendor-hosted PDF against the lab-hosted PDF for three products (retatrutide 10mg, tirzepatide 10mg, GHK-Cu 50mg) and all three matched exactly. This is a stronger check than link-following: every one of the 32 documents was pulled from the lab's own domain, not the vendor's, and the vendor's copies match where I compared them directly.
Benchmark and prices read from the WooCommerce store API on 2026-08-25 (45 products, USD). Retatrutide is listed under its own name, Retatrutide 10mg, SKU RETA10MG, at $200.00, with volume pricing auto-applied at checkout: 2 units $190.00 each (save 5 percent), 3 units $180.00 each (save 10 percent), 5 units $170.00 each (save 15 percent); the same page offers Hospira BAC Water 30ml as an add-on at $27.00 against a $30.00 list price. Also recorded: Retatrutide 15mg $300.00, Retatrutide 30mg $450.00, Tirzepatide 10mg $150.00, Tirzepatide 30mg $400.00, GLP-1 10mg (Semaglutide, SKU SEMA10MG, the compound name appears only in the slug and description) $250.00, Cagrilintide/GLP-1 Blend 5+5mg $200.00, GLOW blend $200.00, KLOW blend $225.00, BPC-157 10mg $80.00, TB-500 10mg $90.00, NAD+ 1,000mg $175.00, GHK-Cu 50mg $70.00, PT-141 10mg $50.00, BAC Water 30ml $30.00. Payment, per the homepage FAQ: 'We accept all major credit cards as well as ACH bank transfers, with a 5 percent discount on ACH payments,' explicitly contrasted against vendors that restrict buyers to crypto, Zelle or Cash App; a separate on-page modal about declined transactions ('contact your credit card issuer using the number on the back of your card') corroborates that card payment is a live checkout path, though I did not reach checkout to confirm a processor name. Shipping, per /shipping-policy/: United States only, free on orders of $200 or more, standard $10, express $15, dispatch within 2 business days; the homepage FAQ separately describes '2-3 day express across all 50 U.S. states' without naming the $10 standard tier, so the two shipping descriptions do not fully align. Entity: the Terms of Service names 'Grey Research Peptides LLC' 11 times, counted on a live fetch today, and not only in boilerplate: the suffix sits in the operative purchaser-warranty clause requiring the buyer's affiliation with a laboratory, institution, university or other research facility, in a clause reserving a due-diligence screening right over information provided, and across an inline privacy block the Terms embed (a second, differently templated privacy policy with its own log-file and cookie sections, distinct from the separate Privacy Policy page) plus email and SMS consent clauses; on every other page loaded today, home, about, quality, product and policy pages alike, the suffix appears zero times, so the Terms of Service is the only page on the site carrying the legal entity's name; the Privacy Policy footer gives contact as info@greyresearchpeptides.com and an address, 215 Southeast 8th Avenue, Fort Lauderdale, FL 33301, US, which I have not verified as a staffed facility versus a mailbox. No telephone number appears anywhere I loaded. The site's own theme configuration carries the flag age_verify: no in its served markup, and no age modal, click-through or date-of-birth field appeared on any page I loaded today, despite the Terms of Service text requiring purchasers to be 21 or older.
CAUTIONCautions noted, all supported by pages loaded today. First, the Privacy Policy is an uncustomized template: it names the site's domain as '1xn874-ur.myshopify.com' and frames the business around a Shopify checkout, while the live store is WordPress and WooCommerce, not Shopify; nothing about that placeholder domain was edited before publishing. Second, a live template variable: the homepage FAQ's refund answer reads 'contact us within [X days] for a replacement or refund,' with the bracketed placeholder left unfilled on the public page. Third, the refund position conflicts across pages: the Terms of Service state plainly, 'ALL SALES ARE FINAL. WE CANNOT ACCEPT RETURNS,' with no carve-out, while the dedicated /refund_returns/ page and the homepage FAQ both describe a money-back purity guarantee tied to the COA, and neither page cross-references the other. Fourth, no age gate exists site-wide (see the prices entry above), which is uncommon though not unique across this ledger: the Peponte Biotech record in the w6 batch, read the same day, likewise gates nothing, while most vendors read for this ledger gate entry behind at least a click-through age confirmation. Fifth, on testing scope: the /quality-and-testing/ page describes endotoxin testing, by the Limulus Amebocyte Lysate method against a stated acceptance criterion of less than 1 EU/mg, in the same list as the HPLC and mass-spectrometry tests it calls standard; none of the 32 certificates obtained directly from the lab's domain carries an endotoxin line, and the same page's own FAQ elsewhere describes endotoxin testing as something a buyer must separately request beyond the standard COA, so the earlier description overstates what the standard certificate actually contains. Sixth, product-page description text for the GLP-class compounds goes well past research framing: the retatrutide and semaglutide pages describe a human dosing route and weekly frequency and cite clinical-trial body-weight and metabolic-marker outcomes in the vendor's own descriptive voice (not solely as numbered references), immediately next to a boilerplate line stating the same compound is not intended for human use; the semaglutide pages in particular are titled 'GLP-1 5mg' / 'GLP-1 10mg' on the catalog and product page, with the compound name appearing in the slug and body text and also in the page's own title tag, og:title and meta description, the strings a browser tab and a search listing display, so the label swap reads as a storefront display choice rather than concealment. Seventh, on staleness: the newest lab accession found for this client dates to 06/08/2026, about two and a half months before this read, and the retatrutide-10mg certificate itself is dated 05/15 to 05/17/2026, roughly three months old, so the document a buyer downloads today is not the most recent testing the lab has done for this vendor. Eighth, the stated purity floor disagrees with itself on the product pages, checked across ten product pages fetched today: the trust badge beside the buy box gives at least 99 percent by HPLC with mass-spectrometry confirmation, while the specification table lower on the same page gives at least 98 percent by HPLC on all three retatrutide pages and at least 95 percent by HPLC on the semaglutide 10mg, GHK-Cu 50mg, epithalon 50mg and thymosin alpha-1 10mg pages, and the refund guarantee is pinned at a purity of 99 percent or better; the benchmark certificate's measured 99.82 percent by HPLC meets both floors, but the pages state two. Ninth, the site's structured data claims a founding date of 2016 in the Organization markup served on the about and quality pages, against a domain creation date of 2025-05-22 in the registry record already cited in entry 0 and a first lab accession dated 05/15/2026, while the visible About copy attributes 2016 to the founder's personal following rather than to the company, so the structured data promotes a personal date into a company founding date that search engines read at face value.
