GHK-CU FAQ
Where can I buy GHK-Cu copper peptide 100mg?
You can buy GHK-Cu online from Blank Peptides in one size, a 100mg vial of the copper peptide complex produced in our cGMP labs in the USA. It arrives lyophilized with the characteristic deep blue cake and a COA tied to the lot number on the label. No prescription, no account approval step. Processing time is within 1 business day.
What is GHK-Cu?
GHK-Cu is the tripeptide glycyl-histidyl-lysine bound to a copper ion. It occurs naturally in human plasma and drops with age, which is what got researchers interested. The published work covers extracellular matrix remodelling, collagen and glycosaminoglycan gene expression, and dermal fibroblast behaviour, mostly in cell culture and animal models.
What purity is your GHK-Cu, and is there a COA?
Greater than 99%. The copper complex is verified by HPLC and mass spectrometry in our lab, then independently at Freedom Diagnostics or Horizon Analytical, with bacterial endotoxin testing on the release batch. Blank Peptides publishes the COA for your exact lot before you order. Copper peptide is one where third-party verification matters, since incomplete complexation is a common quality failure.
How much bacteriostatic water for a 100mg GHK-Cu vial?
3mL. GHK-Cu is an exception to our usual 1mL per 10mg rule because the mass is so high; the vial itself is a 3mL format and 3mL is the ceiling. That yields roughly 33.3mg/mL. Expect a deep blue solution once dissolved, which is the copper coordination and not a contaminant.
Why is GHK-Cu blue?
The colour comes from the copper(II) ion coordinated to the peptide. A properly complexed GHK-Cu cake is blue before reconstitution and gives a clear blue solution after. Pale or white powder sold as GHK-Cu usually means the copper is missing or under-loaded, which is worth checking against the COA whoever you buy from.
How should GHK-Cu be stored?
Lyophilized vials at -20C, sealed, away from light. The complex is reasonably stable at ambient temperature during shipping. After reconstitution keep it at 2 to 8C and protected from light, and use within a few weeks. Copper peptide is more light-sensitive than most of the catalogue, so an opaque box in the fridge is a sensible habit.
GHK-Cu on its own or in the GLOW blend?
How is GHK-Cu shipped, and is it legal to order?
Every GHK-Cu for sale ships from inside the USA with processing time within 1 business day, in plain outer packaging. The compound is sold as a research chemical, not a cosmetic, drug or supplement, and it has no FDA approval for any use. Cosmetic-grade copper peptide is a different regulatory category entirely; this material is for laboratory research.
