Description
Research continues to explore how circadian rhythm signaling peptides and proteins help regulate biological processes tied to sleep, temperature, and environmental cues

In fact, much of the research supports using copper peptides in creams and serums directly on the skin, where they are known to be safe and effective

For unknown compounds or an unknown combination of compounds a single dose toxicity study is needed
Community discussions indicate some researchers prefer AHK-Cu for hair growth applications while using GHK-Cu for broader regenerative purposes
