Does Peptara Labs publish its certificates?
Yes, on its certificates page. Each certificate there is from a recent batch, with lot code, HPLC purity and test date.
Its website also lists the batch certificate for what shipped among the things that arrive with an order. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people.
