Direct head-to-head pharmacokinetic data versus SubQ NAD+ is limited
Pickart, who discovered the peptide, a mixture of GHK-Cu and vitamin C suppressed the growth of a highly malignant cancer in mice called sarcoma-180.9 Anti-pain effects GHK-Cu also appears to possess analgesic, or anti-pain, effects
This interaction increases the risk of side effects like tremors, high blood pressure, and kidney toxicity
However, the study did not achieve its main objective to increase walking distance
