We built GHK-Cu Safe to provide a calm, honest reading of published copper peptide studies. If you spot a number that needs updating or have a question about a cited paper, we want to know.

You're welcome to write our editorial team directly through the form below. We answer questions about published research and correct any factual errors promptly. Did we overlook an important human trial? Please send us the study title and author so our team can review the research paper for your benefit.

A note before you write

Please keep our site's purpose in mind when writing. We summarize published research papers, but we're not doctors and cannot provide personal health advice.

If you're deciding whether a cream fits your skin or hair routine, your own physician or dermatologist can evaluate your personal health history. We also cannot evaluate chemical sellers or recommend specific commercial brands. For questions about your personal care, your healthcare provider is always the right person to ask. That keeps you safe.
