Launching November 2026
A public record for every tested lot.
Bonded Lot is a lot-level certification program for research peptides. Two independent laboratories test each lot, every result is published as measured, and the code on your packing slip opens the record.
Be first to know
Occasional updates about the program. We store what you enter here and the date, and nothing else. We don't share it, and you can ask us to delete it at any time.
How it works
Every lot is double-blind tested
Two laboratories, drawn at random when a testing kit is prepared. The seller can't choose their own laboratory, and our laboratories aren't told whose material they're testing.
Every result is permanently published
Identity, content and purity on every lot, and endotoxin and heavy metals by manufacturing-batch origin. Always published exactly as measured, along with the method. Bonded Lot does not rate results, or judge them as good or bad.
Results are always free
A code on your packing slip opens your lot's results page. Free to read, with no account and no charges, ever. The record is stored permanently for your reference.
For laboratories
We're forming the laboratory panel now. Bonded Lot is your client: we send the samples, we pay you, and the seller never chooses you.
For sellers
Founding-cohort registration is open now. Certify your lots and give buyers a record they can check for themselves, and trust.
Who we are
Bonded Lot is owned by The Bio Logic Foundation. Bonded Lot runs the certification program, works with the laboratories, makes every certification decision and publishes the results.
