Choose the purchasing unit
Bluum lists GHK-Cu in nominal 50 mg and 100 mg vials. The amount is the labeled material quantity, not a solution concentration. Check which variant is selected before continuing to the store.
Keep finished products outside the comparison
A cosmetic serum includes a formulation, packaging and concentration that differ from a lyophilized research vial. Its bottle price is not a directly equivalent price for the laboratory material featured here.
Use nominal amounts consistently
The comparison on this site divides the listed single-vial price by its labeled milligram amount. It does not substitute a particular certificate’s measured result or include shipping, tax or discounts.
Use a size-matched report
The example report describes a 50 mg GHK-Cu sample. Ask for the documentation associated with the actual 100 mg lot if that is the variant you choose. One size’s sample record should not stand in for another without confirmation.
| Nominal amount | Single vial | USD / labeled mg | Checked stock |
|---|---|---|---|
| 50 mg | $45.00 | $0.90 | In stock |
| 100 mg | $59.00 | $0.59 | In stock |
