Lab reports for our range
Independent laboratory analyses of batches from our manufacturer: identity, purity and content per vial, grouped by product and strength.
Why can't I see my batch number?
Batch numbers are made up of the date the batch was produced, which means lot and batch numbers change too often for repeated testing. This page will be updated as and when the manufacturer produces fresh reports.
Please note Peptide Stock does not currently perform any testing. Your batch may not have an active test, but you can see testing from other batches on this page. We rely on the tests provided by the manufacturer, who tests at various laboratories.

Reading a lot number
The lot number is printed on the white box label, below the strength and vial count. It tells you when the batch was made and what's in it.
The product code and strength run together. CP01260813610L is BPC-157 (code 6) at 10 mg, made on 13 August 2026. A report applies only to the exact lot number it shows.
