Prime Peptides

Catalog and pricing read from the live site today. primepeptides.co is a WooCommerce storefront confirming a United States base throughout (see the entity entry below for the street address). Retatrutide is sold at https://primepeptides.co/products/retatrutide/ in three sizes, read from the page's own WooCommerce variation data rather than the single headline price the page renders by default: 10mg (SKU RT10) at 110.00 USD with 1,149 units in stated stock, 30mg (SKU RT30) at 230.00 USD with 1,220 units in stated stock, and 60mg at 295.00 USD. A footnote on the same page states a certificate for the 60mg size 'will be available in mid/late August', so as of this fetch date that size may still carry no batch-specific document. The wider catalog spans exactly 22 named products (per the WordPress product sitemap at /wp-sitemap-posts-product-1.xml, corroborated by the /shop/ archive, whose second page returns no further product links; a GLP-2 filter label on the Testing page is an old slug that redirects to the tirzepatide product page, not a separate item) across GLP-1 style compounds, growth-hormone axis peptides, tanning peptides, blends (KLOW, GLOW, Wolverine) and support items (bacteriostatic water). The product page states the vial is 3ml, reconstituted product is good for 4 to 6 weeks refrigerated, and lyophilized shelf life is 24 months.

Certificates for retatrutide specifically, read from the product page and cross-checked against the full public index at https://primepeptides.co/testing/. Four retatrutide documents are on file: 'Retatrutide 30mg (White Cap)', batch 26071002, purity 99.97 percent by HPLC-UV per the document itself, dated 16 Jul 2026, laboratory printed on the page as 'Freedom Diagnostic'; 'Retatrutide Blue Cap', batch 4122026RT, net content 11.84mg, purity 99.131 percent, dated 26 May 2026, laboratory Janoshik Laboratories, verification key DNFI7M8XE64J; 'Retatrutide 30mg (Purple Cap)', batch 5292026RT, purity 99.505 percent, dated 15 Jun 2026, Janoshik Laboratories, key XIB8E5878V37; and 'Retatrutide Purple Cap', batch 4102026RT, net content 74.45mg, purity 99.82 percent, dated 26 May 2026, Janoshik Laboratories, key MC37SDFQ1EZE. None of the four is labeled '10mg' by name, the size actually sold as SKU RT10 at 110.00 USD; the closest by net content is the unlabeled 'Blue Cap' document at 11.84mg, but nothing on either page states that this cap color is the one shipped for the 10mg SKU a buyer selects at checkout. Separately, two different batches from two different labs (Freedom Diagnostic's 26071002 and Janoshik's 5292026RT) are both presented as the current '30mg' certificate at the same time, with no indication on the page of which one ships against a given order.

Named labs across the whole catalog, checked against the marketing claim that names them. The Testing page's own top blurb names one lab only, stating all peptides undergo third-party purity testing 'conducted by Janoshik Analytics'; the two-lab sentence, 'through our third-party labs: MZ Biolabs and Janoshik', appears instead in a 'Tested Quality' block printed identically on product pages across the catalog (the retatrutide, BPC-157, semaglutide and tirzepatide pages all carry it verbatim), not on the Testing page. The actual public certificate index on the Testing page, all 30-plus entries read today, attributes documents to six different laboratory names rather than two: Janoshik (most entries, listed inconsistently as either 'Janoshik' or 'Janoshik Laboratories', the latter form carrying a verification key and the former not), Freedom Diagnostic or Freedom Diagnostics (retatrutide White Cap and two GLP-2 30mg batches), Horizon Analytical (one GHK-Cu batch), Bioviridian (Glutathione, Ipamorelin and one NAD+ batch), Accumark Labs (one Semaglutide 5mg batch), and Vanguard Laboratory (one Semaglutide batch). MZ Biolabs, the second lab named in the marketing blurb, is not the printed laboratory on any of the certificates in that index. One entry, the Wolverine Blend certificate, carries no laboratory name field at all. Accumark Labs and Vanguard Laboratory are the same two names that appear on Forward Peptides' certificates in an earlier dossier in this batch (dossiers-w6.json), so both are contract labs serving more than one vendor in this market rather than exclusive to either site.

Independently checking the named labs on their own domains today. Freedom Diagnostics Testing (freedomdiagnosticstesting.com, the domain printed on the retatrutide White Cap certificate) is a live, independently operated site describing itself as established in 2023, based at 133 Holiday Ct Suite 106, Franklin, TN 37067, with a public COA lookup and a stated count above 42,000 certificates; the certificate's own printed contact email domain, FreedomDiagnostics.net, does not resolve at all (curl connection failure), a narrower domain than the working FreedomDiagnosticsTesting.com the letterhead also carries. MZ Biolabs (mzbiolabs.com) is likewise a live, real laboratory site: address 2102 N Country Club Rd, Suite C, Tucson, AZ 85716, a stated DEA license number RP0584676, offering mass-spectrometry based testing for research, medical and veterinary markets, though as noted above it is not the printed laboratory on any retatrutide or other certificate found in this session. Janoshik's own verification subdomain, verify.janoshik.com, completed a TLS handshake and returned an HTTP 403 Cloudflare bot challenge to a direct request for each of the three retatrutide verification keys tried today; the janoshik.com root domain failed to complete a TLS handshake at all from this session's toolchain. Both are live, actively defended web properties rather than dead or parked domains, but neither could be read past the bot gate under the curl-only fetch rule, so the specific batch data behind the Janoshik-issued retatrutide certificates could not be independently cross-checked against the lab's own portal in this session, unlike the Freedom Diagnostic document.

Entity, manufacturing claims and cautions. The legal entity is named once, on the Sourcing page: 'Prime Vitality Inc (Prime Peptides)'. The Contact page gives a street address, Prime Peptides, 735 State St Ste 524, Santa Barbara, CA 93101, a phone number, (805) 225-3085, and support hours of Monday to Friday, 10am to 3pm PDT; the same address is repeated as the return-mail address on the Return Policy page. Two pages describe the manufacturing chain differently. The Sourcing page states raw active ingredient comes from facilities in Asia and that only 'processing, packaging, and distribution' happen at the Santa Barbara site, with sterility testing done in-house rather than by a third party. The About Us page, on the same domain, describes a first-person, step-by-step synthesis and lyophilization process, WFI-grade water, mannitol and sucrose excipients, electrospray ionization, a 36-hour freeze-drying cycle, attributed to 'our manufacturing facility' with no overseas sourcing mentioned at all, reading as a claim of complete domestic synthesis rather than the imported-API-plus-domestic-finishing picture the Sourcing page gives. Age-of-purchase language is inconsistent across the site: the retatrutide product page states a buyer 'must be 21 or older', the first-visit disclaimer popup states 'You must be 18 years of age or older', and the Terms of Service uses the unspecified phrase 'age of majority in your state or province of residence'. The Contact page states plainly, in the vendor's own words, that if staff suspect an inquiry is about personal use rather than research, 'we will not be able to help you', which is the clearest acknowledgment on the site that non-research purchasing happens.

Shipping, payment and returns read from /shipping-policy/, /return-policy/ and /terms-of-service/. Shipping is stated as United States only: 'Shipping Areas: USA only', FedEx 2-Day Air at a flat 9.95 USD, free UPS 2-Day on orders over 150.00 USD, dispatched from California on weekdays only with no delivery to PO Boxes; the same page adds the line 'No card transactions are allowed for international shipping' immediately under the USA-only claim, without explaining what shipping scope that sentence is meant to cover. An automated compliance tool named WAAVE is credited with keeping the state-level shipping restrictions in the footer current. Payment across the Terms of Service is credit-card based (the document's privacy language refers throughout to credit card numbers and expiration dates); no cryptocurrency, bank transfer or alternative payment method is named on the shipping, terms or contact pages fetched. Unlike Peptide.Express and Peptide Lab in this same dossier batch, Prime Peptides states an active return path rather than an all-sales-final policy: a 30-day return window with refunds issued to the original payment method within 3 business days of an approved return, gated behind an account login and a Return Request form rather than direct email.
