Heather here is what I was saying on your live today. So, I purchased the raw-ahk-cu (1gram) snap8 and serpen-syl. I added all those raw to cosmedica hyaluronic acid serum and I put it on my scalp. I also do ghk-cu injectable daily and the tiny hairs I have growing is amazing! As I have become older (55) thinner hair and it has helped so much.
