I experienced redness and slight pain (ISR) at the GHK-Cu injection site. How can I relieve this?

The blue copper peptide looks nice, but a red, hard lump appeared after the injection, and it's a bit painful. How did everyone deal with it?

You can add more antibacterial water to dilute the concentration, or it will be much better to mix it with BPC.

I've learned something new; I thought it was an allergy.
