Research Context
What is GHK-Cu researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what GHK-Cu does, and nothing here is a statement that it is safe or effective for any purpose.
Collagen and extracellular matrix
In fibroblast culture GHK-Cu increases production of collagen and other structural proteins that form the scaffold around cells. This is the most reproduced finding and the reason the peptide appears in skincare formulation research. 1
Copper delivery
The peptide binds copper(II) tightly but reversibly, allowing it to carry the ion to enzymes that require it. Several of those enzymes are directly involved in building and cross-linking collagen, which links the two findings together.
Gene expression profiling
Broad screening studies report GHK-Cu shifting expression across a large number of genes in cultured human cells. That breadth is what pushed interest beyond its original wound-healing context, though it also makes specific effects harder to isolate. 1

Verification
Does GHK-Cu come with a COA?
Yes — every box. Each batch of GHK-Cu is analysed by Janoshik Analytical or Freedom Diagnostic. The certificate confirms identity by mass spectrometry and purity by HPLC, and is tied to the batch number printed on the vial label. You can ask to see it before you order.

Questions
GHK-Cu questions, answered
Why is reconstituted GHK-Cu blue?
The colour comes from the bound copper(II) ion. Copper complexes absorb light in the red region of the visible spectrum, so the solution appears blue. A distinctly blue solution on reconstitution is expected for GHK-Cu and is not a sign of contamination.
How much does GHK-Cu cost?
GHK-Cu starts at $7.23 per vial, sold in boxes of 10 vials at $72.28 per box (about £57.10). 2 strengths available: 50 mg, 100 mg. There is no minimum order.
What purity is your GHK-Cu?
All batches test at 99%+ purity. Every box ships with a batch-specific Certificate of Analysis from Janoshik Analytical or Freedom Diagnostic, confirming identity by mass spectrometry and purity by HPLC.
Is there a minimum order for GHK-Cu?
No. You can order a single box of 10 vials. There is no trade account, bulk commitment or minimum spend.
How is GHK-Cu shipped?
Tracked and in discreet, plain packaging, dispatched within 1–3 working days. Delivery estimates are UK 5–7 working days, EU 8–10, USA 5–8 and rest of world 10–12. Full detail is on the shipping page.
