Common questions
How do I know the vial matches the certificate?
Each vial is labelled with a lot number. Enter it on the certificates page and you get that lot's own release panel — purity, identity, net peptide content, water, heavy metals, bioburden and endotoxin.
Is the fill weight all peptide?
No, and no supplier's is. A vial contains peptide plus residual water and counter-ion. We publish net peptide content and water separately so you can work with the real figure rather than assuming the label weight.
What if my own analysis disagrees with yours?
Send it to us. We retain-sample every lot, re-run it, and if the lot is genuinely off specification we refund the order in full, recall the remainder and reimburse your testing cost.
Can you make a quantity larger than the catalog shows?
Yes. Above 500 units of one SKU the order is quoted rather than bought at the door, because lead time, counter-ion form and freight need agreeing first.
Do you give guidance on use?
No. These are chemical reference materials for in-vitro laboratory research. We will discuss purity, analytical method, stability, solubility and storage — questions about the material — but not administration or dosing.
GHK-Cu is supplied as a chemical reference material for in-vitro laboratory research only. It is not a drug or a supplement, it is not for human or veterinary use, and no statement on this page should be read as describing an effect in a living subject.
