Research peptide supplier checklist: record the evidence first
Use one copy for the exact product listing you are reviewing. Save the source and date, and write “not stated” when a page or report leaves a field unanswered.
Update History ▾
Start with the exact product listing
Copy the seller’s product name, format, labelled amount and page URL as shown. Add the date you checked the page. A vial, a pre-filled pen and the sample named on a laboratory report are separate records, even when they share a compound name.
This worksheet records statements and written replies. A blank does not mean a test failed or passed. Keep the gap visible until the seller answers it.

For a missing field, write “not stated” and ask the seller for the exact product, report or policy detail.
Keep identity, content and purity separate
Copy each test name, method, result, unit and sample separately. Identity, measured content or assay, HPLC purity and other named panels answer different questions. A purity percentage alone does not state how many labelled milligrams are in a container.
Match the report’s sample name, format, date and batch code to the seller’s description. A public report describes the sample named on it. If the seller has not documented how that batch relates to the lot being shipped, mark the link as unknown and ask.
For Janoshik reports, keep the public URL, task number and unique verification key together. The step-by-step verification guide shows where those identifiers appear. The COA guide explains why a purity result and a content result belong in different fields.
Save the seller’s current delivery and payment terms
Write down the delivery and dispatch page URL, the quoted timing, every fee or minimum order, the payment instructions and the cancellation or returns page. Record when you checked each link. If a chat reply conflicts with a policy page, ask the seller to clarify the exact term in writing.
For Remy Research orders, see the current delivery terms, refunds and cancellations and official contact channels. For another seller, use that seller’s own published terms and verified contact route.
