Where can I buy GHK-Cu in Canada?

Hermetica Research Labs lists GHK-Cu 50mg and GHK-Cu 100mg as Research Use Only lyophilized vials. Both are ordered from their product pages and ship to Canadian addresses only. Buyers must be 21 or older.

What is the difference between GHK-Cu 50mg and 100mg?

Only the fill mass per vial. Both lines are the same compound, are documented by the same Freedom Diagnostics certificate, and keep their own SKU.

Is the GHK-Cu lot third-party tested?

Yes. The current lot was assayed by Freedom Diagnostics at 99.76% by HPLC-MS (Lot M26S012, COA #2604070134). Match the lot on the vial label against the certificate linked from the product page.

Do you sell topical GHK-Cu or GHK-Cu supplements?

No. GHK-Cu is listed only as lyophilized powder vials for laboratory research. No serums, creams, capsules or supplement products are sold.

How is GHK-Cu stored on receipt?

Both lines are listed for storage at 2–8°C as lyophilized peptide complex. Handling after receipt follows the receiving laboratory's own protocol.

What are the Canada shipping terms for GHK-Cu orders?

Orders ship to Canadian addresses only: flat $15 CAD per order, free on orders of $150 CAD or more, with typical transit of 5 to 12 business days in plain, discreet packaging.

GHK-Cu COA, purity and third-party testing

The current GHK-Cu lot was assayed by Freedom Diagnostics, an independent third-party laboratory. The certificate reports 99.76% purity by HPLC-MS for Lot M26S012 (COA #2604070134). One certificate covers both the 50mg and 100mg lines, and each line keeps its own SKU. The certificate is linked from both product pages and listed in the Certificates of Analysis library.

A purity figure describes the sample that was assayed. It does not establish suitability for any use outside in-vitro laboratory work. For the fields to check, see how to read a RUO COA and the Freedom Diagnostics verification checklist.

How to match a GHK-Cu vial to its certificate

Read the compound name, fill mass (50mg or 100mg) and lot number from the vial label.
Confirm the same lot (M26S012) appears on the Freedom Diagnostics certificate linked from the product page.
Confirm the certificate number (#2604070134) and check it on the issuing laboratory's own system where it is published.
Keep the certificate with the invoice and packing slip in the reagent record.
