Derek i just saw your video on mixing your GHK-Cub serum.
You did it exactly how I believe it works best.
I did saw a Peptide vendor selling their GHK-Cu serum and they state it has (2) bottles of GHK-Cu 100mg and (8) Bottles of Snap 8.
What do you think of that, definitely there not using Cosmetic GHK-Cu
