Peptriva Review References

Eight sources carry every factual claim in this Peptriva review. Each one is a document a reader can open without asking us for anything.

Note on references

Every numbered citation in this issue resolves to one of the eight sources below, and every source is a primary document rather than a summary of one. Four are Peptriva's own: the certificate ledger, the terms of sale, the shipping policy, and the catalogue. Two sit outside the company: the third-party laboratory named on every certificate, and the United States Pharmacopeia chapter the endotoxin assay is run against. One is the contact record. One is the regulation that governs how a company may publish a review of itself.

The most load-bearing is the first. The certificate ledger is where the purity figures, lot numbers, accession numbers, net content values, endotoxin results, and test dates on every plate come from, and it is where a reader should go to check that this publication transcribed them correctly[1]. Where this site and a certificate disagree, the certificate governs and this site is in error.

About the certificates cited

The ledger carries the analytical record: twelve published rows, fourteen certificates, thirteen lots, one issuing laboratory, and one date pair of 30 June 2026 received and 2 July 2026 reported[1]. Each certificate reports five assays and carries an accession number from the laboratory's own document system, which is the field that makes a citation here checkable rather than decorative.

The laboratory reference exists so that the name on a certificate can be confirmed as a real testing operation rather than a letterhead[2]. The terms of sale carry the seller of record, the returns position, the four claim windows, the Out-of-Spec Guarantee, the age gate and attestation, and the research-use-only conditions[3]. The shipping policy carries the carrier, the cut-off, the processing window, the destinations, and the packaging description this issue relies on when it declines to make a cold-chain claim for the parcel[4]. The catalogue carries the listed products, the categories, the stock state, and the price range[5]. USP General Chapter <85> is the standard the duplicate endotoxin assay is run against[6]. The contact page carries the distribution address, the telephone number, the support addresses, and the hours[7]. And 16 CFR Part 465 is the federal rule governing review authenticity and consumer-review practices[8].

One document is cited nowhere, because it is not published: the production certificate required by the release rule before a lot can be sold. Its absence from this list is the honest shape of the record rather than an oversight.
