About these certificates. Values shown reflect the most recently published lot for each product. Batch numbers and results are specific to that lot; the live certificate for the lot you receive is linked from each product page and ships referenced on your order. BPC-157 and TB-500 are currently documented through the combined blend lot — a standalone-lot certificate for each will be posted here once tested.
