The honest summary is that long-term human safety data is missing and the angiogenesis mechanism is an unresolved theoretical concern
Determining it independently requires either three separately quantified chromatographic peaks with real response factors, since ultraviolet response at 214 nm scales with peptide-bond count and area percent is therefore not mass percent, or LC-MS with one extracted ion channel per component, plus an elemental copper number
For direct fat reduction, Tesamorelin (visceral fat reduction) and CJC/Ipamorelin (growth hormone stimulation for lean body composition) are more relevant than GHK-Cu
However, when given subcutaneously, GHK-Cu bypasses this barrier and the peptide gets into circulation systemically at the desired dose
