Recorded from Imperial Peptides’s own public website on 29 Jul 2026. “Not stated” means we did not find the information on their site, not that it is absent from their business.

Notes
- The COA page publishes 77 outbound links to batch certificates hosted by Janoshik. The links are public and require no login; the certificate host blocked automated retrieval, so the certificate contents were not inspected.
- Stated purity differs between the COA page and product spec tables.
