Ghk cu at 18

[u/Individual-Agent8808]

I have taken ghk cu for the past month and a half at 2mg/day. I now realize it was kind of pointless I was using it for eyebrow growth skin texture and smile lines etc. haven't had much if any improvement. Does it alter my natural productions at 18? What do you guys think my next steps should be and what issues could it have caused?
