FAQ
Where can I buy copper peptide for research?
Here. Astral lists the copper peptide as GHK-Cu in 50 and 100 mg vials, supplied for laboratory research only. Pick a size above to order.
Is GHK-Cu the same as copper tripeptide-1?
Yes. GHK-Cu is the tripeptide Gly-His-Lys bound to a copper ion, CAS 89030-95-5. Copper tripeptide-1 is its name on cosmetic ingredient lists, and copper peptide is the everyday shorthand.
Is GHK-Cu legal to buy?
Astral supplies GHK-Cu as a research chemical for laboratory use only, not as a cosmetic, supplement or medicine. It is not for human or veterinary use.
How fast does it ship?
Orders ship from our own inventory in New York. Standard, 2-Day and Overnight options, with arrival dates for your address, are shown at checkout.
Storage
All our compounds are stored and shipped in lyophilized form for stability. Lyophilized peptides are stable at room temperature for many months. Once your order arrives, use our Astral H₂O or an equivalent solvent to reconstitute. Peptides are not as stable in reconstituted form. They should be refrigerated and used within 4-6 weeks.
