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.
USA Peptide Sciences' own homepage metadata addresses a rival's shutdown by name, reading in part, "Peptide Sciences closed?" before promising 160-plus USA-made peptides at "99%+ purity," while the Quality Assurance page gives 99.5 percent plus as a line-wide average rather than a per-lot reading, and no page fetched names or links a testing laboratory. Ten pages fetched directly on 2026-09-02, including the retatrutide 12mg product page's own promise that every order ships with a batch-specific Certificate of Analysis, turned up no certificate on any of them, and checkout itself is manual: the vendor states a buyer places an order, then waits to be contacted with payment instructions, with a stated preference for cryptocurrency and no card network named. No street address or legal-entity name appears on any page fetched; the only phone number found sits inside the live-chat widget's own configuration, and the domain itself is young, registered 2026-05-14. Has a buyer who ordered here received the promised certificate, and did it name a testing laboratory?
What the record holds
STATED WINDOW IN DAYS
“two paid tiers, Standard at seven to fourteen business days and Express at three to seven business days, with cost calculated at checkout rather than published”
Read from the shipping-policy page as recorded in the dated entry. No dispatch cutoff and no handling time are published anywhere read, and the companion walk records the Terms stating orders are not processed or shipped until payment confirmation is received by email under the site’s manual off-platform payment flow, an untimed step in front of the tier windows; under the weaker-when-ambiguous rule no cutoff-timed or same-or-next-day class is available and the stated windows in days are the only timed commitment on record. The same policy page states free Express shipping automatically applied at two hundred fifty US dollars or more and worldwide shipping in packaging it describes as unbranded; the walk separately priced the cart at $14.99 Flat rate Express, preselected as the default, against $7.00 Flat rate Standard for the $230.00 benchmark vial, figures read from the cart rather than from any published rate table.
Read from this supplier's own pages on 2026-09-02. This publication has never placed an order with any supplier. This row records what is written and measures nothing about what actually happens after an order.
Compound retatrutide 10mg
Listed as No 10mg strength exists in the catalog. The compound is sold only as Retatrutide 6mg, Retatrutide 12mg and Retatrutide 16mg, each its own product page with no additional brand code, e.g. https://usa-peptidesciences.com/product/retatrutide-12mg/
Price as recorded Not benchmarkable at ten milligrams because no such vial is sold. In United States dollars, the vendor's actual strengths read directly from each product page today are Retatrutide six milligrams at one hundred eighty dollars, twelve milligrams at two hundred thirty dollars, and sixteen milligrams at two hundred ninety five dollars. None of these three figures is a ten milligram price and none should be substituted for one.
Read on 2026-09-02. 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.
7 claims from this publication's own dossier on this supplier were read again against the live site on 2026-09-02: 1 held, 6 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.
Dated entries
6 observations on file, recorded 2026-09-02. Newest first, appended and never rewritten.
On certificates and labs: ten pages fetched directly today (home, /product/retatrutide-12mg/, /product/retatrutide-6mg/, /about-us/, /quality-assurance/, /manufacturing-standards/, /contact-us/, /disclaimer/, /terms-conditions/, /privacy-policy/) and none of them links or displays a certificate of analysis, whether as a PDF or a gallery image. The retatrutide 12mg product description states in its own copy that every order is shipped with a comprehensive, batch-specific Certificate of Analysis, but no such document is attached to that page; the string COA appears four times on that page (in a page-wide header banner about batch verification and COA documentation, in the product description's own parenthetical spelling of Certificate of Analysis, and twice inside a customer-review paragraph), and none of the four is a hyperlinked or embedded document. The site's own page-sitemap.xml, fetched directly, lists thirteen URLs and none of them is a certificates or COA index. Purity is stated as a fixed average rather than a per-lot reading: the Quality Assurance page gives 99.5 percent plus as an average purity rating across the product line, and the same page and the Manufacturing Standards page both describe HPLC and mass spectrometry as the general testing methods used, so the average figure is method-qualified only in a general, not a per-lot, sense. No testing laboratory is named anywhere on the ten pages fetched; the recurring phrases are qualified third-party laboratories and qualified suppliers, neither pointing to a checkable lab name or site, so no lab could be verified because none is identified.
On catalog scope and the retatrutide benchmark: product-sitemap.xml, fetched directly, lists 161 product URLs, matching the homepage meta description's claim of 160 plus compounds. Categories seen in the site's own navigation include growth hormone peptides, bioregulator peptides, cosmetic peptides, collagen peptides, a category using an age-reversal marketing label, peptide capsules, melanotan peptides, immune support, sexual health and libido, plus one category oriented to body-composition research and one oriented to lean-tissue and anabolic research. No 10mg retatrutide vial exists in the catalog: the only strengths sold are Retatrutide 6mg, Retatrutide 12mg and Retatrutide 16mg, each its own single-vial WooCommerce product page (for example https://usa-peptidesciences.com/product/retatrutide-12mg/) with no additional brand code and no kit or multi-vial-only structure, so KIT-VS-VIAL does not apply here. JSON-LD Offer prices read directly from each page today: Retatrutide 6mg at one hundred eighty US dollars, Retatrutide 12mg at two hundred thirty US dollars, and Retatrutide 16mg at two hundred ninety five US dollars. None of these three figures is a 10mg price and none should be read as one.
On payment and shipping, fetched directly from /about-us/, /contact-us/ and /shipping-policy/: there is no automated checkout payment gateway. Both about-us and contact-us state in the site's own words that after an order is placed the team contacts the buyer with payment instructions, that the minimum order is one hundred US dollars, and that a five percent discount applies to cryptocurrency payment. No card network, processor brand, PayPal, or similar is named anywhere on the ten pages fetched, and the /cart/ page carries no payment-method selector, consistent with an off-platform manual-payment flow rather than an on-site checkout. Shipping-policy states two paid tiers, Standard at seven to fourteen business days and Express at three to seven business days, with cost calculated at checkout rather than published, plus free Express shipping automatically applied on orders of two hundred fifty US dollars or more; the same page states shipping is worldwide, to the United States and internationally, in packaging described on the page as unbranded and intended to reduce attention at customs and to protect buyer privacy.
On entity and contact details: across all ten pages fetched today there is no street address and no registered company or legal-entity name. A telephone number IS published, though only inside the live-chat widget's own embedded configuration, present in the page HTML on every page fetched: a click-to-call channel at tel:+15126788813 and a matching SMS channel on the same number, +1 512-678-8813 (re-verified in the live HTML of https://usa-peptidesciences.com/contact-us/ on 2026-09-02). The other stated contact channels are the email service@usa-peptidesciences.com and the live chat itself, carrying a claimed five to fifteen minute response time. The disclaimer page states products are not evaluated or approved by the FDA, EMA, or any other regulatory body and excludes human and animal use, clinical application, and use outside intended laboratory research applications; it places compliance responsibility on the buyer. None of the ten pages fetched names a parent company, a business registration number, or a jurisdiction of incorporation.
LOOKALIKE ANGLE, established-brand resemblance: the site's own SEO metadata, read directly from the live homepage HTML on 2026-09-02, addresses the closure of the established Peptide Sciences brand by name. The meta description tag reads verbatim: "Peptide Sciences closed? We carry 160+ USA-made research peptides CJC-1295, Semaglutide, BPC-157 & more. Same COA standards, 99%+ purity, free express shipping $250+. Research use only." (source: view-source of https://usa-peptidesciences.com, fetched 2026-09-02). The page title tag reads verbatim: "USA Peptide Sciences | Buy Peptides Online | 99%+ Purity, COA-Verified" (same source). Both are the operator's own words, addressed to search engines, naming the Peptide Sciences brand and its closure as the reason to consider this storefront. I did not find, on any of the ten pages fetched, a claim by the operator to be the same company, a successor company, or formally affiliated with peptidesciences.com, nor did I find a denial of affiliation; the standing ledger record for peptidesciences.com (dated 2026-08-20, not refetched in this pass) already documents that domain returning HTTP 403 and its catalog and pricing gone, and separately lists five other lookalike domains it had identified as of that date, none of which is usa-peptidesciences.com. RDAP for usa-peptidesciences.com, fetched directly from Verisign's RDAP service on 2026-09-02, shows registration on 2026-05-14, registrar Key-Systems GmbH, nameservers ns1 through ns4.ultahost.com, and a redacted registrant contact (privacy service), so no registrant-identity evidence either way. This is a young domain, under four months old at the time of this fetch, built on WordPress and WooCommerce with a black-and-orange brand skin; I did not refetch peptidesciences.com this pass, so no direct markup comparison between the two sites was made. On the facts gathered today this reads as a same-category competitor whose own marketing copy explicitly targets search interest in the Peptide Sciences name and its closure, without an express claim of being that company; I have not found evidence either way of shared ownership. Flagged here for the operator to arbitrate rather than adjudicated by me.
CAUTIONCautions supported by fetched pages: (1) no testing laboratory is named anywhere on the ten pages fetched, so the 99.5 percent average purity figure and the HPLC and mass spectrometry claims are vendor self-attestation with no linked, checkable third-party document; (2) no certificate of analysis, PDF or image, is attached to either retatrutide product page despite the product copy's own claim that one ships with every order; (3) payment runs off-platform and manually, with the buyer contacted after placing an order rather than paying through an on-site gateway, and a stated preference for cryptocurrency; (4) no legal-entity name or street address is published anywhere on the site; the published contact channels are an email address and a live-chat widget whose own embedded configuration carries phone and SMS channels at +1 512-678-8813; (5) the domain is new, registered 2026-05-14, roughly three and a half months before this fetch; (6) the site's own SEO copy is built around the closure of the established Peptide Sciences brand, without an explicit claim of affiliation, a fact recorded here for the operator's attention rather than resolved by me.
