For BPC-157 specifically, the FDA reported limited and short human studies, a lack of adequate studies for several commonly used routes of administration, potential immunogenicity concerns, possible liver and clotting signals in animal studies, and three adverse-event reports, while noting that a cause could not be established
The most productive research direction, based on the current evidence base, involves combining GHK-Cu treatment with multi-omics approaches (transcriptomics, proteomics, and metabolomics) to build a more complete picture of how the compounds gene-level effects translate through the entire cellular response cascade
PDI has two active sites, both of which are characterized by the presence of a CGHC motif, which either forms a disulphide for the enzyme to become active as an oxidase, or a dithiol for the enzyme to act as an isomerase
The body then excretes a metal-cysteine mixture
