GHK-Cu

Plasma copper peptide used in dermal and repair research. Solution is blue.

What it does / how it works

A copper-carrying tripeptide found in plasma. It changes gene expression toward collagen, elastin and antioxidant enzymes and is used in skin and repair research. The blue colour is the copper.

Class	Copper tripeptide-1
Typical vial	50 or 100 mg
Reconstitution	2 mL per 50 mg = 25 mg/mL, or 5 mL for easier draws
Storage after mix	2–8°C, use within 28 days

Protocol

Goal	Dose	How often	How long	Route
Weeks 1-2	0.5 mg	Once daily	2 weeks	SubQ
Weeks 3-8	1.0 mg	Once daily	6 weeks	SubQ
Off	None	Stop	2-4 weeks off	–

Watch: Account for total copper if stacked with AHK-Cu or KLOW.

GHK-Cu FAQ — Australia

Where can I buy GHK-Cu in Australia?

GHK-Cu is available from ELV8 Labs in 50 mg and 100 mg vials. Every batch is independently tested at a leading Australian university. For research purposes only.

Why is reconstituted GHK-Cu blue?

The blue colour comes from the copper(II) ion complexed with the GHK tripeptide. This is normal and expected — copper(II) solutions are characteristically blue. A clear, blue-tinted solution indicates proper reconstitution. If the colour appears brown or murky, the compound may have degraded.

Can GHK-Cu purity be measured by HPLC?

GHK-Cu produces multiple peaks on RP-HPLC due to the copper–peptide complex chemistry. Standard purity percentages are not directly comparable to non-copper peptides. LC-MS (mass spectrometry) is the preferred method for confirming GHK-Cu identity and is the method used by Australian testing laboratories.

What is the difference between GHK-Cu 50 mg and 100 mg?

The peptide is identical — the difference is the amount per vial. The 100 mg vial offers better value for longer research protocols, while the 50 mg vial is suitable for shorter cycles or researchers wanting to trial the compound before committing to larger quantities.

Does GHK-Cu need to be reconstituted with acetic water?

No. GHK-Cu dissolves readily in standard bacteriostatic water. Acetic water (dilute acetic acid) is only required for certain peptides that are poorly soluble at neutral pH — GHK-Cu is not one of them.
