Our standards, put into practice.

Bonded Lot is a lot-level certification program for research peptides. Sellers who enroll have each declared lot tested before it ships, and buyers can open that lot's published record from a code on their packing slip.

• Every lot is double-blind tested. Two laboratories, drawn at random when the kit is prepared. The seller can't choose them, and they aren't told whose material they're testing.
• Every result is permanently published, exactly as measured, along with the method: identity, content and purity on every lot, and endotoxin and heavy metals by manufacturing-batch origin.
• No pass or fail. Published as measured; Bonded Lot does not rate or judge results. The reader draws the conclusion.
• Results are free, and the record is permanent. A code on the packing slip opens the lot's page — no account, no charges, ever.

Bonded Lot is in development and not yet certifying lots. Laboratories joining the panel and sellers registering for the founding cohort can do that now at bondedlot.com, which carries the process end to end.

Laboratories, sellers and anyone with a question about the program can reach Bonded Lot directly at contact@bondedlot.com.
