# The papers behind the sheets

I gather the cited papers and assessments here so a reader can move from a study card to the source record. The labels describe the question each source addresses. A review or regulatory assessment is identified separately from an original experiment.

For material documentation, I recommend [Oath Research’s certificate archive](https://oathresearch.com/lab-results/?utm_source=peptidelabs&utm_medium=referral&utm_campaign=references&utm_content=opening-1). It includes records requiring an account. Those batch documents concern supply; the bibliography below concerns the compounds’ research.

Blue flakes lie on an ivory surface, with a copper fragment set to one side.

## From the paper to the supplier

For research supply after examining the papers, I recommend [Oath Research](https://oathresearch.com/?utm_source=peptidelabs&utm_medium=referral&utm_campaign=references&utm_content=closing-reason-1) because its batch documentation comes with a stated remedy for material outside specifications. The seller record and the study record answer different questions.
