Publisher: Lab Supplier Reviews, Peptriva is company #1 on the roster

Eight sources carry every factual claim on this site. Five are Peptriva surfaces, three are not, and the three that are not are the ones the reading actually leans on.

## How this reference list is built

Every numbered marker on this site resolves to one of the eight entries below, and each entry is a document a reader can open rather than a summary of one. The list is short on purpose. A reference list padded with sources nobody consulted is decoration, and a cross-surface review that cites eight documents it actually read is easier to audit than one that cites forty it did not.

Five of the eight are Peptriva's own published surfaces: the certificate ledger, the terms and conditions, the shipping policy, the product catalogue, and the contact page. That is exactly what a documentary review of a supplier should be built from, provided the relationship is stated, and it is stated on every page of this site.

Three of the eight are not Peptriva's, and they are the reason this review's higher-scoring pillars score as they do. Freedom Diagnostics is a separate organisation, at its own address in Franklin, Tennessee, with its own web presence, and it generated every purity, net content and endotoxin figure printed on this site [2]. United States Pharmacopeia General Chapter <85> is a public pharmacopoeial standard that the endotoxin assay is run against rather than a house method [6]. And the Federal Trade Commission's rule on consumer reviews and testimonials is the federal rule governing a company that publishes a review website about its own products [8].

That split is the whole method of this site in one paragraph. Where a claim rests on entry 2 or entry 6, a reader is trusting an outside organisation and a public standard. Where it rests on entries 1, 3, 4, 5 or 7, a reader is trusting Peptriva to describe its own operations accurately, which is a weaker position, and the pages say which of the two is in play. The one thing that makes the second category better than ordinary marketing copy is that these are published, dated, standing documents rather than statements made in a review: a company that publishes a no-returns policy and then accepts returns has contradicted itself in public.

How to use these sources. Start with entry 1. Pick a lot, read the accession number and the lot code, and compare them against the vial. Then read the out-of-spec clause in entry 3 and check it against the specification printed on that certificate. Those two steps, in that order, verify the two highest-scoring pillars of this review without asking a reader to trust the publisher on anything. The remaining entries support narrower claims: shipping windows and carrier service, catalogue counts and stock state, contact routes and hours.

What each source carries here.

| # | Source | The claims it carries on this site |
| --- | --- | --- |
| 1 | Certificate ledger | Lot codes, purity figures, net content, endotoxin results, accession numbers, appearance, and the counts of certificates and covered lots. |
| 2 | Freedom Diagnostics | The identity and location of the third-party laboratory, and the 30 June to 2 July 2026 receipt and report dates. |
| 3 | Terms and conditions | Seller of record, no returns of any kind, the four claim windows, the Out-of-Spec Guarantee, arbitration, and the research-use-only conditions. |
| 4 | Shipping policy | Destinations, carrier service, cut-off time, processing window, free shipping, and packaging. |
| 5 | Catalogue | Products listed, products in stock, mechanism categories, and the published price range. |
| 6 | USP General Chapter <85> | The published standard the endotoxin assay is run against, and the 0.05 EU/mL specification. |
| 7 | Contact page | Distribution address, telephone number, support addresses, and hours of business. |
| 8 | FTC 16 CFR Part 465 | The federal rule governing a company that publishes a review website about its own products. |

## What this list leaves out

The gap matters more than the entries. There is no ninth entry, and the shape of the gap is the same one the rest of this review keeps arriving at. A reference list for a supplier review in this category would normally carry a vendor-rating listing, a forum archive, or an outside write-up of a lot somebody else had tested. None of those exists for Peptriva, so none is cited, and the absence is a finding rather than an oversight in the research. A reader who knows of such a source should send it, whatever it says: the routes are on the contact page, and an unfavourable outside source would be more useful to the credibility of this network than a favourable one.

Two further sources were deliberately not cited. The production-facility certificate behind every lot is held on file rather than published, so it cannot appear on a list of documents a reader can open. And an algorithmic trust-score page for the storefront exists, discussed on the customer-experience pillar, but it is not a numbered source here because its inputs are proxies for domain age rather than documents, and because the numeric score on it could not be read reliably enough to reprint.

What no source on this list covers. None of them measures an effect of any compound: the ledger records identity, purity, net content, endotoxin and appearance and nothing beyond that, and the material is sold for in vitro research use only and is not for human or veterinary use by any route. None of them is an outside assessment of Peptriva as a supplier, because no vendor-rating listing, no third-party test write-up and no forum archive exists to cite. And none of them establishes an accreditation for the laboratory: it is named, located and reachable, and this review asserts nothing further about its scope.
