Supplier certificate. Testides tested this sample for PeptiLab, the supplier who manufactured the material we resell. It was not commissioned by Sentient Biogenix, and the lot shown is the supplier lot rather than a lot we have matched to our own stock. We publish it because it is the best documentation that exists for this product today, and we would rather show you that than show you nothing.
