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.
Regena Peptides' own COA library caption admits its certificates carry different supplier letterheads because the vendor uses more than one tested and verified supplier. Two documents opened directly bear that out: the 10mg, a Janoshik Analytical report, lists its client as jack@zybiopeptides.com rather than Regena, and the 50mg, whose own library card points its verify key at janoshik.com, is signed by a different company, Chromate, directing verification to chromate.org; neither names Regena as client. The trust badges read "EU Sourced" and "Tested & shipped from EU", yet the Shipping Policy states parcels ship from hubs in China, Germany, or the United States, and payment instructions warn buyers not to mention peptides in a bank transfer note or "your payment will be stopped by the bank." Has any past buyer confirmed which lab's certificate, if either, actually matches the vial that arrived?
What the record holds
STATED WINDOW IN DAYS
“dispatch prepared within one to three working days”
From the Shipping Policy as quoted in the dated entry, with transit windows of 5 to 14 days for Spain, the rest of Europe and the UK, 5 to 18 days for the US and Canada, and 7 to 21 days rest of world, all tracked. The same policy states parcels ship from one of our fulfillment hubs in China, Germany, or the United States, which the record sets against the site's own EU Sourced and Tested and shipped from EU badges. No cutoff time is stated, and a one-to-three-working-day window is not a same-or-next-day commitment, so the stated-window class applies.

Compound retatrutide 10mg
Listed as Retatrutide, the 10 mg per-vial strength option among seven kit sizes on the /peptides/retatrutide product page; the site does not sell single vials, only sealed ten-vial kits, so this is a kit price covering ten vials at 10mg each, not a single-vial price
Price as recorded Priced in euros, not United States dollars, and checkout itself is stated to run only in euros regardless of the display-currency switcher shown to visitors. The ten milligram per vial kit is the second cheapest of seven kit sizes: five hundred sixty-nine euros for the ten-vial kit, which the page's own per-unit maths renders as fifty-six euros ninety cents per vial and five euros sixty-nine cents per milligram. Full range and payment and shipping detail recorded in the entries above.
Read on 2026-08-26. One reading on one day, and prices are not tracked over time here.
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.

Certificates are published from a central COA library at /coa, fetched today, listing dozens of batches by product name, a batch code, mg content against label, method, analysis date and a verify key, most attributed on the page to Janoshik Analytical. The library's own caption admits inconsistency: it states COAs may show different supplier names or letterheads because Regena uses multiple tested and verified suppliers, and if one partner is out of stock it sources from another approved supplier so a verified batch is always shown. Retatrutide appears on nine cards in the library, eight carrying a labelled per-vial strength, 10 and 30 mg twice each and 15, 20, 50 and 60 mg once each, plus one unlabelled blind-panel card, with analysis dates running from 27 Jun 2025 to 26 Apr 2026. I opened two of the retatrutide documents directly, the 10mg batch RETA-10-2026-01 and the 50mg batch 040126R50Y, rather than trusting the page's summary. Batch RETA-10-2026-01, verify key USHTNKXVYDE7, downloads as a Janoshik Analytical Test Report: task number 103742, testing ordered 24 Jan 26, sample received 29 Jan 26, analysis conducted 2 Feb 2026, sample described only as Retatrutide 10mg, manufacturer Unknown, batch Unknown on the document face itself (the RETA-10-2026-01 code is Regena's own label, not anything printed on the certificate), a Retatrutide quantity of 10.42 mg and a purity of 99.794 percent, no testing method stated anywhere on the document, only a QR code and the verify key. The client of record printed at the top of that report is jack@zybiopeptides.com, not Regena Peptides. I also opened the 50mg retatrutide batch, 040126R50Y, verify key VIDA1T32ATAE, whose library card lists Method HPLC, matching the document behind it, but links its verify key to janoshik.com/verify. The document itself is not a Janoshik report: it is a Chromate Certificate of Analysis, COA #34290, produced by a company that is not named Janoshik anywhere on the page, client listed as VidaLabs at vidalabshop@yahoo.com, sample received 4/24/26, analysed 4/26/26, method printed on the document as qualitative and quantitative chemical analysis by RP-HPLC with UV detection (no mass spectrometry), quantity 55.41 mg against a 50mg label (plus 10.8 percent of label), purity 99.875 percent, signed Lucas Weber, Principal Chemist, and its own verify instruction reads chromate.org/verify rather than janoshik.com. Neither of the two retatrutide documents I opened names Regena Peptides as the submitting client, and the 50mg card's verify-portal attribution on Regena's own site does not match the document behind it; the method overstatement runs the other way, on the 10mg card, which prints Method HPLC + MS against a document that states no method at all.
On lab verifiability, exercised directly rather than described. Per FETCH RULES I requested janoshik.com and janoshik.com/verify with the specified Chrome user agent; both attempts failed to complete an HTTP fetch through this session's client. A raw TLS connection opened cleanly (confirmed via a direct openssl handshake, certificate chain validates to Let's Encrypt), but the plain HTTP request returned 403 Forbidden carrying the response header Cf-Mitigated: challenge, meaning Cloudflare's bot mitigation is blocking the request rather than the origin refusing it. A second attempt with Python's own HTTP client, a different TLS stack, same user agent, returned the identical 403. Janoshik's identity could not be independently confirmed via its own site from this session; the majority of Regena's published certificates rest on a name I was not able to verify today. Chromate, the second name found on the site's own certificates, did load. chromate.org resolves to a live page today describing itself as an Unannounced Independent Testing project aimed at the dietary-supplement and fitness community, chemists trained in the USA, Canada, Germany and Singapore, and a Verify portal that itself states javascript must be enabled to access database, confirming the portal exists but could not be queried through this fetch method either. No ISO or other accreditation mark appears anywhere on Chromate's homepage. Regena's own homepage and COA page credit its reports jointly to Janoshik Analytical and VidaLabs, but VidaLabs is not a laboratory on the certificate that actually carries that name: it is the client, contactable at a yahoo.com address, submitting a sample to Chromate, the same pattern as the unrelated zybiopeptides.com client on the Janoshik-format retatrutide document above.
Benchmark and prices read on 2026-08-26 from /peptides/retatrutide and its embedded variation data. Retatrutide is not sold as a single vial anywhere on the site; the product page states this outright and the catalogue enforces it: every order is a sealed ten-vial kit, seven kit sizes by per-vial strength (5, 10, 15, 20, 30, 50, 60 mg), each vial in a kit holding the same labelled strength. Priced in euros, not United States dollars, and the currency selector is display-only: the page itself states that prices display in your currency but every order is charged in EUR. The ten milligram per vial kit is the second cheapest of the seven: five hundred sixty-nine euros for the ten-vial kit, which the page's own per-unit maths renders as fifty-six euros ninety cents per vial and five euros sixty-nine cents per milligram. The five milligram kit undercuts it at five hundred nineteen euros per kit and the sixty milligram kit tops the range at nine hundred forty-nine euros per kit. A bundle widget on the same page offers a Tirzepatide ten-vial kit at 5mg per vial alongside a ten-pack of bacteriostatic water as a frequently-bought-together bundle. Payment, read from the Shipping Policy page: three options, SEPA or international IBAN bank transfer with no fee, a second SEPA or IBAN account described as bunq with no fee, and card payment processed through Wise; no card is charged directly. The same policy instructs, verbatim, on the second bank account: "Remember: don't say anything about peptides in the payment reference or notes, or your payment will be stopped by the bank." Shipping: dispatch prepared within one to three working days, and the policy states verbatim that parcels ship from one of our fulfillment hubs in China, Germany, or the United States, followed, after a dash, by whichever route delivers to you fastest and most reliably; transit windows given as 5 to 14 days for Spain, the rest of Europe and the UK, 5 to 18 days for the US and Canada, and 7 to 21 days rest of world, all tracked. Entity and contact: the Contact page gives WhatsApp, Telegram and an email address, plus Marbella, Málaga as a location for local meetings by appointment; no registered company name, no company number and no VAT number appear anywhere I fetched. The Terms and Conditions state only that the site is operated by Regena Peptides, based in Marbella, Málaga, Andalucía, Spain, and that Spanish law and the courts of Málaga govern. The sitewide footer renders a fragment, verbatim, as it appears in the page's own text flow: "Regena PeptidesVAT Marbella, Málaga, Andalucía, Spain", with the word VAT preceding the location and no VAT number ever printed.
CAUTIONCautions noted, each tied to a page fetched today. First, both retatrutide certificates I opened directly name a client other than Regena Peptides (jack@zybiopeptides.com on the Janoshik-format 10mg document, VidaLabs at a yahoo.com address on the Chromate-format 50mg document), while the COA library's own caption acknowledges letterhead inconsistency without disclosing that the named client differs from the vendor on every document I checked. Second, an attribution mismatch on the 50mg batch: Regena's library card links its verify key to janoshik.com/verify and the library's own caption credits its reports to Janoshik Analytical, while the underlying document is signed by a different company (Chromate), names client VidaLabs rather than Regena, and instructs verification at chromate.org/verify instead; the card's stated method, HPLC, does match that document's RP-HPLC with UV detection. The method overstatement sits on the 10mg card instead, which prints Method HPLC + MS while its own document states no method anywhere on its face. Third, a direct sourcing contradiction: the site's own trust badges read, verbatim, "EU Sourced" and, immediately under it, "Tested & shipped from EU", while the Shipping Policy states in its own words that parcels ship from one of our fulfillment hubs in China, Germany, or the United States, naming a non-EU country as one of three dispatch points for the same orders those badges describe. Fourth, the payment-instructions quote above directs buyers to omit any reference to the product category from a bank transfer note so the transfer is not stopped by the receiving bank. Fifth, no registered legal entity, company number or VAT number could be found on the Contact page, the Terms and Conditions, or the footer, which prints the word VAT next to a city name with no number following it. Sixth, Janoshik itself could not be verified via its own site this session, documented above, so the name behind most of the catalogue's certificates remains unconfirmed from this end. Seventh, every downloadable certificate and every delivery-proof photo or clip on the site that I checked is hosted at a filename in the pattern IMG-YYYYMMDD-WA followed by four digits, the naming convention a phone applies automatically to media saved from WhatsApp, for both the certificate scans and the unboxing footage the homepage presents as delivery proof.
