Supplier-reported results for PE 22-28

Third-party lab results the vendors below commissioned and reported to us. For most vendors we publish the numbers but not the certificates themselves: the lab documents name the supplier, and our suppliers sell to us on the basis that we don't route customers around them. Where a vendor's certificates don't name them, or the vendor sells here under its own name, we link to the lab's own copy. Results whose certificate we can publish are in the COA library.

Each result covers the batch it names. Vendors ship thousands of kits and restock continuously, so there's no guarantee your order comes from a batch listed here.
