Reading a GHK-Cu certificate
Purity is measured by reverse-phase HPLC on a C18 column with detection at 214 nm — the trace shown under each batch above. The figure is the share of the signal in the GHK-Cu peak, and it is reported against the specification printed beside it.
Identity is confirmed separately by LC-MS, which checks the mass of what is in the vial against what is expected for GHK-Cu. Purity without identity would say how clean the sample is, not what it is.
Net content is the measured quantity in the vial against its stated fill. Endotoxin is reported against its limit, sterility as growth or no growth, and heavy metals as a screen for arsenic, cadmium, lead, mercury.
Verify a batch yourself
Every certificate carries a Kovera Labs report number and access code, both published above. Enter them at koveralabs.com/verify and the laboratory returns its own copy of the record. Vials ship unlabeled, so the batch number for your order is on the certificate supplied with your shipment.
FREQUENTLY ASKED
4 ITEMSDoes GHK-Cu come with a certificate of analysis?
Yes. 2 batches of GHK-Cu have a published certificate, covering the 50 mg and 100 mg fills. Every fill currently in the catalog is covered.
What purity is GHK-Cu tested to?
The published batches were tested by reverse-phase HPLC against a purity specification of more than 98%. They returned 99.568%–99.847%, reported at the precision the laboratory issued.
Who tests GHK-Cu?
Kovera Labs, a third-party laboratory. Every certificate carries a Kovera Labs report number, and each batch is tested for purity, identity by LC-MS, net content, endotoxin, sterility, and heavy metals.
How do I verify a GHK-Cu certificate?
Enter the report number and access code printed on the certificate at koveralabs.com/verify. Both are published for every batch on this page. Vials ship unlabeled, so an order's batch number is on the certificate that ships with it.
