Question 1

How can I check the COA?

Accepted Answer

Every lot of GHK-Cu is assayed by HPLC for purity (label claim ≥99.0%) and by mass spectrometry for identity. The independent Janoshik report for this item is in the testing queue and will be published in the lab verification section of this page. Until then, request the lot-matched certificate of analysis from info@nordgenlab.com with your order number.

Question 2

How should I store the product after receiving it?

Accepted Answer

Sealed vial: Store lyophilised powder at -20°C, protected from light. Keep it in the original packaging, protected from light and moisture, and let it reach room temperature before opening to avoid condensation. Once reconstituted with bacteriostatic water, store the vial refrigerated at 2–8 °C, protected from light, and avoid repeated freeze–thaw cycles. Reconstituted material is far less stable than the lyophilised powder, so prepare only what your protocol needs. For laboratory research use only.

Question 3

How long does it take to ship to my country?

Accepted Answer

All orders are dispatched within 24 hours of payment confirmation, Monday to Friday. European Union and EEA destinations typically arrive within 3 business days; other destinations depend on the carrier and local customs handling. Everything ships in discreet, insulated packaging with tracked delivery, and the tracking number appears in your account as soon as the parcel is scanned. Full details are on the Shipping information page.

Question 4

Can I order in bulk — are there discounts for larger quantities?

Accepted Answer

Yes. Volume pricing is applied automatically per line at checkout: 3+ vials — 10% off, 5+ vials — 15% off, 10+ vials — 20% off. Quantities between tiers use the nearest tier below, so 7 vials receive the 5+ rate. Discounts apply per product and vial size, and no code is needed — the saving is shown in the cart. For quantities beyond the top tier or recurring lab supply, contact info@nordgenlab.com for a quote.

Question 5

What should I do if the shipment is damaged or incorrect?

Accepted Answer

Contact info@nordgenlab.com within 7 days of delivery with your order number and photos of the outer packaging, the vial and the label. Under the Nordgen Guarantee, anything that arrives damaged, incorrect or compromised in transit is replaced free of charge — we ship the replacement as soon as the photos are reviewed, and you never need to return a compromised vial before it is resolved.

Question 6

What sizes of GHK-Cu are available, and what arrives in the vial?

Accepted Answer

GHK-Cu is supplied as sterile lyophilised powder in a single vial size: 50mg. Vials ship sealed under vacuum with no solvent included — bacteriostatic water is sold separately and can be bundled with this order at a discount. Purity is stated as ≥99.0%. Supplied strictly as a research chemical for in vitro laboratory use, not for human or veterinary use.
