Cancer-history question sheet for a GHK-Cu product or exposure

Write down your cancer history, the exact GHK-Cu product and route, and whether you are considering it or have already used it, then take the sheet to your oncology or prescribing team. It gathers what they need to interpret the question; it does not set a waiting period or a verdict.

What the evidence on this page does and does not show

  • The VEGF finding comes from cultured skin fibroblasts of people treated with radiation, grown without serum; it is a cell result, not a tumor or patient result.[1]
  • The angiogenesis finding maps mostly to the related sequence KGHK, cut from the protein SPARC, in laboratory models.[2]
  • A systematic review published online in August 2026 found 20 studies, 18 preclinical and 2 randomized trials, and noted few well-designed clinical trials.[3]
  • FDA says human data to inform the safety of injected compounded GHK-Cu are limited.[4]

Questions for the oncology or prescribing team

  1. Given my cancer type and treatment, does a product that affects wound repair or blood-vessel growth concern you?
  2. Does my current treatment or an upcoming procedure change your answer?
  3. If I have already used it, is there anything you want to check?
  4. Who on my care team should know if I start or stop it?
