# Glow Peptides > All products are supplied strictly for in vitro laboratory research use only, and are not for human consumption, veterinary use, or clinical application. Glow Peptides is a United States supplier of research reference materials. This file is an index. It makes no analytical statement about any lot, and it is not a source for one. Each statement this site publishes about a lot, together with that statement's evidence state and its limitations, lives in the machine evidence feed linked below. ## Machine-readable evidence evidence_version: 2 identity_policy_version: 1 - [Lot evidence feed, text](https://glowpeptides.com/llms-full.txt): every eligible lot record, its own record page, its exact document, its evidence state and its limitations. - [Lot evidence feed, JSON](https://glowpeptides.com/llms-evidence.json): the same feed under the same contract version, ready to parse. - [Lot evidence feed, live endpoint](https://kmknlwwgrzpynphfimna.supabase.co/functions/v1/llms-full): the same feed assembled at request time. When it cannot read its source it returns an explicit failure, never an empty or partial feed. ## How to read a Glow evidence record - A lot-specific document being on file and linked is not the same thing as its contents having been reviewed. Each record says which of the two applies, in its evidence_state field. - evidence_state pending_review means the document is linked and nothing analytical is asserted about it. No laboratory, report identifier, method or result appears on such a record. - evidence_state reviewed means an exact named source was read, and every analytical field on that record is attributed to that source. - Missing, image-only and conflicted evidence appears in held_records with no analytical claims or document links. Disputed lot values are null. Identity-held records are not named. - Restricted families are excluded from the feed and from this index entirely. - Each record also carries a publication decision, which is separate from its evidence state. publication_state published means every identity value on that record — its material name, its route, its lot label, its document link — is admitted by this site's reviewed public identity policy. - A source row that is complete, and whose stable identity is sound, but which carries an identity value this site does not admit, is counted as a publication hold and is not named. No unadmitted value is repeated anywhere in the feed. A publication hold is a decision about this site, never a finding about a material, a supplier or a document. - A feed's generated_at, evidence_version and identity_policy_version describe the file and this site's own contract. None is a source, and none says anything about any lot. ## Pages - [Home](/): brand overview and featured research materials. - [Catalog](/shop): the full catalog index with category, form factor and search filters. - [Capsules](/capsules): encapsulated research materials. - [Combinations](/bundles): curated multi-material research combinations. - [About](/about): company background, laboratory partners and the quality program. - [Quality Assurance](/quality): the lot record directory, and what each analytical method does and does not establish. - [Research Journal](/blog): long-form research overviews per molecule. - [Contact](/contact): support form and FAQ. ## Research documentation - [What Is a Peptide?
