ghk-cu for skin tightening Peptide Labz Copper Peptide Body Lotion, 10 fl oz, Firming and Hydrating GHK-CU (InfiniWell)

Keep Bacteriostatic Water (BAC) in its original labeled container and follow the product documentation or manufacturer instructions supplied with the order

Label the vial with date and concentration immediately after mixing

Storage duration critically impacts effectiveness - reconstituted GHK-Cu lasts only 21-28 days refrigerated due to copper oxidation concerns (shorter than most peptides), requiring strategic reconstitution of amounts usable within this window rather than preparing entire vials at once

If you prefer more forgiving measurements, the 5mg vial with 2mL gives you a lower concentration with larger, easier-to-read unit markings on your syringe
