In this brief video, Katie Mullen shares her experience starting GHK-Cu peptide injections and addresses viewer concerns about the injection feeling "spicy"—a burning, bruising sensation at the site. She references a tip she saw to add extra backwater (diluent) to the syringe after drawing up the peptide, aiming to further dilute the solution and lessen discomfort. Katie demonstrates the method: she draws up six lines (approximately 5‑6 mg) of peptide, then adds about 20 mg of additional diluent to the syringe, explaining that this extra volume simply dilutes the peptide more before injection.

Peptide video from yesterday when I started GHKCU. A lot of the comments that I got were asking if it was spicy. I guess this one's known to kind of like hurt a little bit at the injection site and burn and feel like a bruise for a while. I saw somebody give a tip to put some extra backwater in the syringe after you pull the peptide out to help dilute it a little bit more. So I'm going to try that. I'm going to draw up six lines, however much that is. 5, 6. Then I'm gonna draw up 20 additional milligrams of this to help dilute it. Just dilutes it down a little bit, and that's it.
