There is also a basic characterization step that would help before any of that: independent analytical confirmation of what is actually in research vials peptide purity, the true copper-to-peptide ratio, and the absence of endotoxin and contaminants so that findings can be tied to a defined substance rather than to material of unknown composition
The FDA has specifically evaluated it as a bulk drug substance for compounding and raised questions about its safety profile and the adequacy of available data
