Nextday Peptides publishes a /coas/ library of 12 certificates against a 60-product catalog, six of them covering its retatrutide line, sold as GLP3, with fill weights running over label on every one of those six rows, from 4.8 percent over on a 60mg lot to 12.6 percent over on a 15mg lot, and no analytical method named on the listing grid itself. The library states plainly that searchable certificates cover box orders only, with single-vial documentation available by request, while /payments-refunds-returns/ and /terms-conditions/ both state COAs are available "for all products" with no such qualification. Of the four labs that actually issue those 12 rows, Janoshik, Freedom Diagnostics, and Krause Analytical are each locatable operating businesses, but BT Labs, issuer of the retatrutide certificate shown by default, resolves to a parked domain under every spelling tried; a fifth name, ILS Laboratories, appears in the library's own descriptive prose and the site's FAQ but issues none of the 12 rows. Has a customer who ordered a single vial rather than a box of ten actually received the documentation the library promises on request?
What the record holds
NO FIRM COMMITMENT
“a same-day processing cutoff the About page states as '3:30 PM EST' Monday through Saturday”
Classed on what the record quotes under the weaker-when-ambiguous rule, not on the name's next-day implication: the cutoff is a processing statement on the About page rather than a dispatch commitment in the policy, and the Shipping and Delivery Policy hedges throughout. Overnight is available at checkout on qualifying orders, Monday-through-Thursday overnight orders typically arrive the next business day, delivery estimates are stated as estimates only, and fulfilment runs through third-party partners, with one order able to ship from different locations. Service levels overnight, 2-day expedited and standard; carriers FedEx, UPS and USPS; U.S. domestic addresses only; free shipping on single vial orders over $300 and box orders over $500.

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.
1 claim from this publication's own dossier on this supplier were read again against the live site on 2026-08-26: 1 held, 0 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 dedicated /coas/ library rather than embedded per product page in the primary flow, fetched today at nextdaypeptides.com/coas/. The library states a total of 12 Certificates of Analysis and the listing itself holds exactly 12 rows, each carrying a SKU, a batch number, the issuing lab, a cap color, a milligram strength, a fill weight, a purity figure and a date, with Preview and Download controls per row. Of the 12, six cover the GLP3 line the site sells as its retatrutide compound (SKU NDP-056): 60mg batch 510006 issued by BT Labs, cap purple, fill 62.9mg against a 60mg label, purity 99.9 percent, dated 7/20/2026; 50mg batch 2026051250 issued by Janoshik, cap green, fill 56.04mg, purity 99.69 percent, dated 5/25/2026; 30mg batch 510005 issued by Freedom Diagnostics, cap purple, fill 36.19mg, purity 99.86 percent, dated 7/27/2026; 15mg batch 2026061215 issued by Janoshik, cap black, fill 16.89mg, purity 99.17 percent, dated 6/23/2026; 10mg batch 510002 issued by Krause Analytical, cap white, fill 11.2mg, purity 99.9 percent, dated 7/13/2026; and 20mg batch 510004 issued by BT Labs, cap blue, fill 22mg, purity 99.9 percent, dated 7/1/2026. No analytical method is named on the library grid itself for any row; a purity figure sits beside the lab's name with no chromatography or mass-spectrometry term attached at the listing level. The remaining six rows cover TB-500 (Freedom Diagnostics), three GLP2 strengths the site sells as tirzepatide (all three Janoshik), NAD+ (Janoshik, purity field reads N/A against a 500mg label filled to 540mg), and one GLOW blend (Freedom Diagnostics). The library page states its own scope directly: 'At this time, searchable COAs are provided for box (10-vial) orders only,' with single-vial documentation 'available by request only (subject to documentation availability)' through orders@nextdaypeptides.com. Against a catalog of 60 distinct product URLs counted from /products/ today, these 12 lot documents cover five compound lines by name, so most of the 60 listed peptides carry no published certificate at all, box or single. The retatrutide product page itself (/product/glp3-reta-research-compound/) shows a COA tab that defaults to the 60mg BT Labs row (batch 510006, purity 99.9 percent) and swaps to a different lot-matched row as a size is picked, but the page's own structured data describes every one of its 13 purchase options, seven single-vial sizes from 10mg to 60mg and six box sizes, with the identical line 'Certificate of Analysis available on request,' which is a narrower promise than what the COA tab actually displays for the default selection.
On the labs, and four names actually issue the 12 rows in the current /coas/ library: BT Labs, Janoshik, Freedom Diagnostics and Krause Analytical. A fifth name, ILS Laboratories, is added only in the library's own descriptive prose ('labs named on individual records may include Janoshik Analytical, BT Labs, Krause Analytical, Freedom Diagnostics, and ILS Laboratories') and repeated in the FAQ answer to 'Which labs appear on Nextday Peptides COAs?', yet it issues none of the 12 rows the library actually lists. Janoshik and Freedom Diagnostics were both independently verified as live analytical laboratories in an earlier dossier pass dated 2026-08-25: janoshik.com resolves to a live laboratory site carrying a report verification route, and freedomdiagnosticstesting.com resolves to a live laboratory site in Franklin, TN with a working lookup by search code; neither states an accreditation claim on its own homepage. BT Labs, issuer of two of the six GLP3 rows including the one the retatrutide page shows by default, has no locatable operating site: btlabs.com, fetched today, is a bare parked-domain page from the registrar Safenames stating 'There is no website configured for this address yet'; bt-labs.com and btlaboratories.com both fetched today as a one-line redirect stub pointing to /lander, the same parking pattern an earlier dossier pass found behind an unrelated lab's domain. No spelling beyond these three was tried. Krause Analytical is locatable: krauselabs.com redirects to www.krauselabs.com, fetched today, a Squarespace site titled 'Krause Analytical' whose service list includes 'peptide testing' alongside corn and grain testing, import detention and food testing, synthetic color testing, and what it labels BP-a and bp-s testing; it gives a contact address printed on the page as 'PO Box: 8127 Mesa Drive, Suite B206, Austin, Texas, 78759' and an email of info@krauseanalytical.com. Its homepage makes no accreditation statement of any kind; the terms ISO, 17025 and accreditation appear nowhere in the fetched page. ILS Laboratories is also locatable, at ils-lab.com, fetched today along with its application bundle: it names ILS Labs Inc. as the testing operator and ILS Analytical LLC as the platform and billing entity, gives an address of 8222 Vickers St, Suite 106, San Diego, CA 92111, a phone number of (619) 329-3999, an email of info@ils-lab.com, and states it was founded in 2019. Its meta description and repeated headline copy across Home, About, the FAQ and its Terms page state plainly that it is 'ISO 17025 accredited,' yet across the full application bundle the only appearance of the accreditor name A2LA sits inside a generic blog post explaining what ISO 17025 accreditation generally requires and which bodies typically grant it, naming A2LA, ANAB and PJLA only as examples of accreditation bodies in general, not as a statement of which body accredited ILS Laboratories itself; no certificate number and no scope are given anywhere in the fetched material for the claim the site repeats as a headline. So of the four labs actually behind Nextday Peptides' published certificates, two are independently confirmed live laboratories carrying no accreditation claim of their own (Janoshik, Freedom Diagnostics), one has no locatable operating site under any of three domain spellings tried (BT Labs), and one is a real, address-carrying laboratory that also states no accreditation claim (Krause Analytical). ILS Laboratories, the fifth name in the site's own prose, issues none of the 12 published rows and carries an accreditation claim its own published material does not name an accreditor for.
Benchmark and catalog read from the live product page and its WooCommerce variation data on 2026-08-26. Retatrutide is sold under the name GLP3 Reta, SKU NDP-056, also labelled GLP3-R on the vial image and GLP3 in the COA library, CAS 2381089-83-2, at /product/glp3-reta-research-compound/. Kit-vs-vial, the page offers 13 purchase options: seven single vials, 10mg $100.00, 15mg $120.00, 20mg $140.00, 30mg $180.00, 40mg $220.00, 50mg $260.00, 60mg $300.00, and six 10-vial boxes, 10mg $600.00, 15mg $720.00, 20mg $840.00, 30mg $1,080.00, 50mg $1,560.00, 60mg $1,800.00 (no 40mg box is offered). The 10mg single vial at $100.00 is the benchmark figure; the 10mg box works out to $60.00 per vial, 60 percent of the single-vial price. For comparison, kit-vs-vial again: BPC-157 (SKU NDP-003) sells as a 10mg single vial at $60.00, a 20mg single vial at $100.00, and only one box size, a 10mg 10-vial box at $360.00, or $36.00 per vial. Tirzepatide, sold as GLP2 Tirz (SKU NDP-054), runs from a 10mg single vial at $80.00 to a 60mg single vial at $240.00, with box pricing that does not scale evenly across strengths, for example a 5mg box priced at $246.00 against a 15mg box priced at $366.00, and a 70mg through 90mg box tier priced well under the per-mg rate the 10mg through 60mg boxes follow. The catalog holds 60 distinct product URLs under /products/, counted today. Shipping is disclosed at /shipping-and-delivery-policy/ and repeated on /about-us/ and the product page: fulfilment from 'U.S. warehouses located in Florida, North Carolina, and California,' overnight, 2-day expedited and standard service levels, free shipping on 'single vial orders over $300 and box orders over $500,' carriers FedEx, UPS and USPS, U.S. domestic addresses only, and a same-day processing cutoff the About page states as '3:30 PM EST' Monday through Saturday with standard delivery by 'USPS Ground Advantage.' The vendor's own name implies a next-day delivery commitment; the policy text actually published is narrower and hedged throughout: 'Overnight shipping is available at checkout on qualifying orders,' Monday-through-Thursday overnight orders 'typically' arrive the next business day and Friday overnight orders 'typically' arrive Monday, and a standing qualifier states that 'Delivery estimates provided on the Website...are estimates only and are not guaranteed delivery dates unless explicitly stated otherwise.' The policy also discloses, in its own words, that fulfilment runs through 'independent fulfillment partners, suppliers, logistics providers, and third-party operational partners' and that 'Products may ship from different fulfillment locations' within a single order, so the brand's overnight offer is conditioned on which partner and location fills a given item rather than a blanket transit-time promise attached to the name. Payment methods, read from /payments-refunds-returns/: credit and debit cards 'when shown at checkout' (Visa, Mastercard, American Express and Discover named, 'subject to processor availability'), Link Money, bank transfer, Zelle, Venmo, Cash App, cryptocurrency, and check or money order 'by arrangement' with remittance instructions supplied after checkout. The page states 'All Sales Final,' cancellations are 'Not accepted once fulfillment has begun,' and disputes are asked to route through support 'before initiating any chargeback.' Entity and contact: legal entity Nextday Sciences LLC, doing business as Nextday Peptides, governed by Florida law per /terms-conditions/, with a mailing address of 7901 4th St N #33829, St. Petersburg, FL 33702, a suite-number format consistent with a private mailbox rather than one of the stated fulfilment warehouses, and a single published contact channel, orders@nextdaypeptides.com; no telephone number appears on any page fetched today.
CAUTIONCautions noted, all sourced to pages fetched today. First, an internal contradiction on COA scope: the /coas/ library states plainly that box orders are the only orders with a searchable published certificate and that single-vial documentation is 'available by request only (subject to documentation availability),' while both /payments-refunds-returns/ (quick-reference table row: 'COAs Available for all products, for reference only') and /terms-conditions/ (FAQ answer: 'COAs are available for all products in our COA Library') state the opposite without that qualification. A visitor reading only the two policy pages, rather than the library page itself, would reasonably expect a certificate on any purchase, including a single vial, when the library's own text says the opposite. Second, a lab-naming gap: ILS Laboratories is named in the library's descriptive prose and its own FAQ as one of the labs whose documentation may appear, but issues none of the 12 rows the library actually lists; the four labs that do issue those 12 rows are Janoshik, Freedom Diagnostics, BT Labs and Krause Analytical. Third, an unlocatable issuing lab: BT Labs, issuer of the retatrutide certificate the product page shows by default (60mg, batch 510006, purity 99.9 percent) and of one other GLP3 lot, has no operating website found under any of three domain spellings tried today, two of which resolve to parked or lander-redirect pages rather than a laboratory. Fourth, an unsupported accreditation claim at the one lab among the four that does make one: ILS Laboratories states 'ISO 17025 accredited' as a headline claim across its Home, About, FAQ and Terms pages, fetched today along with its full application bundle, without naming an accreditor or a certificate number anywhere in that material; its only mention of A2LA sits inside a generic explainer of what accreditation bodies are in general, not a statement that A2LA, ANAB or PJLA accredited ILS Laboratories itself. Fifth, no analytical method is stated on the /coas/ library grid for any of the 12 rows; a purity percentage sits beside a lab name with no chromatography or mass-spectrometry term attached at the listing level, so a visitor cannot learn the identity-confirmation method from the library page alone. Sixth, fill weight runs over label on every one of the six GLP3 rows, from 62.9mg on a 60mg label (4.8 percent over) to 16.89mg on a 15mg label (12.6 percent over) to 11.2mg on a 10mg label (12 percent over), with no note anywhere in the library or on the product page explaining the overage; the same pattern appears on the NAD+ row, 540mg against a 500mg label, whose purity field reads N/A rather than a number, so the one row without a numeric purity figure is also the one with the largest labelled overage. Seventh, the brand name carries a delivery promise the policy text hedges everywhere it appears: same-day processing applies only 'before 3:30 PM EST,' overnight delivery is offered as an option 'available on qualifying orders' rather than a standard, and the Shipping & Delivery Policy's own force-majeure and third-party-fulfilment sections place responsibility for a missed timeline outside the company once a shipment leaves its hands, so the name describes a checkout option rather than a guaranteed transit time on every order.
