Do GHK-Cu capsules work the same as injectable or topical GHK-Cu?

This is a real concern with peptides you swallow. Digestion breaks down most peptides before something like GHK-Cu could be absorbed whole. That is why its research and cosmetic use is on the skin, not swallowed. No study in people in this site's review has tested whether a GHK-Cu capsule is absorbed or does anything. So a capsule rests on a different, unproven idea than the skin products that have real research behind them.
