Supplier Evidence Checklist | Peptide Choice Guide

Use this checklist to record what a supplier makes public, what can be linked to a specific lot and what remains unknown. It is a note-taking aid, not a quality score or purchasing recommendation.

Record the evidence before drawing a conclusion

Check only what you can see in the source material. The tool does not measure product safety, efficacy or suitability for human use. A completed list means that records were located; it does not independently validate those records.

Documentation review

Mark each item only when the relevant record is accessible and specific enough to inspect.

The supplier identifies the material with a specific product name.

A lot or batch number is shown or can be matched to the record.

The document shows a test, issue or release date.

The analytical method is stated rather than implied by a marketing label.

The document separates an acceptance criterion from the reported result.

The issuing laboratory or responsible quality unit is identified.

There is a realistic route to inspect or verify the original record.

The review date and any unresolved gaps are recorded.

No items recorded yet.

How to use the result

The summary tells you how much of this documentation checklist you have recorded. It deliberately does not turn the result into a supplier or product rating. A full checklist can still leave important questions unanswered, including chain of custody, manufacturing consistency, current inventory and suitability for human use.

Keep source status visible

Next to each record, note whether it is supplier-provided, provider-verifiable, directly inspected or secondary. Those labels make it easier to revisit the evidence later without forgetting where a claim came from.
