Visual PeptideSuppliers & Sourcing
We aim to list suppliers that have been third-party tested (e.g. Janoshik) or are otherwise vetted by the research community. Listing is for information only; always verify purity and compliance yourself.
Verification first
Before choosing a supplier, check the Purity & Verify page and use the public Janoshik database to see which batches and vendors have test reports.
Supplier directory
Labs/suppliers with available third-party test results. We add entries as reports are verified. Listing does not imply endorsement.
No suppliers listed yet. We will add entries as third-party test reports (e.g. Janoshik) are verified. If you are a supplier and want to be considered, ensure your batches are tested and reports are verifiable via the lab's official site.
