The peptide degradation research overview covers the compound integrity considerations, and the peptide purity and COA interpretation guide covers content verification

Primary risks include additive cardiovascular effects (increased heart rate and blood pressure), intensified gastrointestinal symptoms (nausea, vomiting, diarrhea), and potential for serious adverse events including pancreatitis and acute kidney injury requiring close monitoring

But it is important to remember: GHK-Cu is not magic
