Hair Growth Peptides such as GHK-Cu and keratin-derived peptides are used in serums and supplements to promote thicker, healthier hair
Keep each peptide in its own vial, draw with its own syringe, and inject at separate sites
If dullness persists beyond eight weeks without improvement, your GHK-CU may be degraded or your skin may simply not respond well to this peptide
