Lot lookup
The lot number is printed on every label, in the format ZEN-YYMM-NNN. This looks up any lot with a published independent result — for any other lot, email us the number and we’ll tell you exactly what we hold for it.
The full ledger
Every one of these is lot-numbered, so each vial traces back to its batch. Anything marked verified below has been through an independent laboratory. Supplier paperwork varies by batch, so ask about any lot and we’ll tell you exactly what we hold.
What “lot-numbered” means. Every vial carries a lot number recorded against the order it went out on, so we know exactly which batch it came from and where that batch went. It does not mean we have independently tested it, and supplier paperwork varies from batch to batch — we won’t call anything verified until an independent laboratory has tested it.
Independent testing costs several hundred pounds per compound and gets added as trading supports it. Each result is published here as it lands — BPC-157 is verified already. Our full position →
When your brand goes on the vial, our standards become yours. This ledger is how you check them.
