We supply only a tag like BPC 157 +TB 500 10MG for example to BT Labs at great expense for peace of mind. BT Labs adds brown handwritten Untested label for certificate visual showing vial received untested then blind tests via HPLC and LC-MS. We list net content and HCL because HCL adds weight, so net shows true pure active peptide measured by nitrogen analysis. We do this for all our products for peace of mind for us TB BIO but more Importantly for Peace of mind for our Clients.We have been asked why don't we send a random product with labels on it which we can do for future batch testing coming up soon .
