How is a solution prepared?
This is how solutions are prepared in the lab.
Step 1 of 8: Disinfect
The stoppers of both vials are wiped with an alcohol swab.
- Disinfect. The stoppers of both vials are wiped with an alcohol swab.
- Draw up. The needle passes through the stopper of the bacteriostatic water and the plunger draws up liquid.
- Transfer. The liquid runs down the inside wall of the vial with powder.
- Mix. The vial is gently swirled until the solution is clear.
- Done. The solution is ready for use in research.
- Take sample. A new needle passes through the stopper and the plunger draws up part of the solution.
- Sample vial. The solution runs through the septum of the screw cap into a sample vial.
- Analyze. The sample vial goes into the autosampler; the instrument measures the solution in vitro.

What is GHK-Cu?
GHK-Cu is a copper peptide: the complex of the tripeptide GHK with one copper(II) ion. Pickart and Thaler described the tripeptide in 1973 in Nature New Biology, as a substance in human serum. In 1977, Schlesinger, Pickart and Thaler established in Experientia which three amino acids it consists of. PubChem and DrugBank list no approval of GHK-Cu as a medicine.

Purity and COA for every batch
An external laboratory measures purity by HPLC (≥99%) and identity by mass spectrometry. With GHK-Cu, check which mass the COA reports: that of the free peptide GHK or that of the copper complex. Both are correct as long as the certificate says what was measured. Find the COA for your batch number on Lab results.
Storage and shipping
Keep the vial shut and store it cool, dry and dark, as the label and COA indicate. GHK-Cu travels from Europe in insulated packaging with tracking, with a cold pack when it is warm. Received and paid before 3 p.m. Central European time on a working day? Then it leaves that day; delivery takes 1–3 working days within Europe. EU only.

Questions about GHK-Cu
Where can I buy GHK-Cu?
GHK-Cu is available from PulseChem in this web shop. Prices start at €39.95 including VAT for 50 mg, and GHK-Cu is in stock. Orders received and paid before 3 p.m. Central European time on a working day leave the same day; delivery takes 1–3 working days within Europe. Each batch comes with a COA.
What is in a vial of GHK-Cu?
A vial of GHK-Cu contains 50 or 100 mg of lyophilized powder: the tripeptide GHK with bound copper(II). The vial is glass and sealed, and the label states the amount and the batch number. Use that number to find the batch's COA on Lab results.
How is GHK-Cu shipped and stored?
GHK-Cu ships from Europe in insulated packaging with a tracking number, with a cold pack in warm weather. Delivery takes 1–3 working days within Europe. After arrival, keep the closed vial cool, dry and dark, as the label and the COA indicate.
What is the difference between GHK-Cu powder and the GHK-Cu serum?
The difference between GHK-Cu powder and the GHK-Cu serum is the form. GHK-Cu powder is lyophilized powder in a 50 or 100 mg vial, with ≥99% purity by HPLC. The GHK-Cu serum is a 30 ml bottle of liquid containing 0.33% GHK-Cu. Both have a batch number and a COA for every batch and are for laboratory research only.
Background from the knowledge base
What are peptides?
A peptide is a short chain of amino acids joined by peptide bonds. How peptides differ from proteins, which peptides occur in nature, and which items in the catalog are not peptides.
Peptide blends: reading the label and the COA
A blend is one vial holding two or more compounds in a fixed ratio. How the label states the amount, how such a mixture is measured, and what belongs on its certificate.
