Draft analytical review: surveys of unregulated peptide supply
Consultation on the draft analytical evidence review of published surveys of unregulated peptide supply. The review assesses what such surveys establish, and records that the great majority of them cannot establish the provenance of the material analysed and…

§1.2Consultation questions
The secretariat put the following questions. A submission was not required to address them and several did not; the questions record what the Institute was uncertain about rather than restricting what a respondent could raise.
- Is the provenance criterion applied consistently across the included surveys?
- Should a survey that cannot establish provenance be included at all, or excluded with the reason recorded?
- Does the review state clearly enough that a purity distribution across purchased samples is not an estimate of the purity distribution of any supplier's output?
§1.3How a submission is handled
- Every submission is signed. The Institute publishes no anonymous submission.
- Every submission carries a declared interest. A declaration of no interest is itself a declaration and is recorded as one. A declaration is not a disqualification and the Institute has never given a submission less weight on that ground.
- A submission from an employee of a marketing-authorisation holder is identified as an industry submission on its face, following a unanimous consultation on the conflicts policy.
- Every submission receives a secretariat response and a disposition. Submissions that are not accepted remain published in full; the Institute does not remove a submission because it disagrees with it.
- There is no voting, no reputation score, no reply thread and no editing after receipt.
§1.4Outcome
The review was amended before ratification. Surveys without establishable provenance are included and reported separately from those with it, rather than pooled, and the distinction between a sample-level and a supplier-level claim is stated in the abstract.
The disposition table, listing each submission with its disposition and the resulting amendment, is at §3.
