I'm considering using GHK-CU to help with my gastritis recovery since it's known to repair the stomach and intestinal linings. From what I've read, the average dose is 2-3mg per day. It's suggested to split this into two doses due to its half-life. I'm unsure about how much copper actually enters the blood at this dose, and I'm also wondering about the right amount of zinc to balance it out. Any advice on this would be greatly appreciated.
