GHK-Cu questions
What is GHK-Cu?
+
Copper-binding tripeptide (Gly-His-Lys) complexed with copper. Extensively studied in tissue, dermal, and wound-research models. pepuro supplies GHK-Cu as a lyophilized (freeze-dried) powder in sealed vials for in-vitro laboratory research only. It is not for human or animal use.
What vial sizes of GHK-Cu does pepuro sell?
+
pepuro sells GHK-Cu in 2 vial sizes: 50mg, 100mg, starting at $24.99 CAD per vial. Every size ships free anywhere in Canada.
How is pepuro's GHK-Cu tested?
+
Every batch of GHK-Cu is tested by an independent third-party laboratory (such as Janoshik Analytical) using HPLC for purity and mass spectrometry for identity. pepuro does not ship a batch below 99% purity by HPLC. Each vial carries a QR code that opens the lab report for the exact batch it came from, so the result can be checked for the vial in hand rather than a generic product PDF.
Read moreWhat are the CAS number and molecular weight of GHK-Cu?
+
GHK-Cu has CAS number 49557-75-7, molecular formula C14H22CuN6O4, molecular weight 403.91 g/mol. The identity and purity of the specific vial you receive are on that vial's own lab report.
How should GHK-Cu be stored?
+
Unopened lyophilized GHK-Cu vials are stored in a freezer at -20°C for long-term storage, or refrigerated for short-term storage. Once reconstituted, the vial is kept refrigerated. Repeated freeze-thaw cycles degrade peptides and should be avoided.
Read moreHow is GHK-Cu reconstituted?
+
GHK-Cu ships as a dry powder and is reconstituted with bacteriostatic water before laboratory use. pepuro's free reconstitution calculator gives the resulting concentration for every GHK-Cu vial size at any water volume.
Read moreDoes pepuro ship GHK-Cu across Canada?
+
Yes. pepuro ships GHK-Cu free to any address in Canada by Canada Post in plain, unbranded packaging. Orders ship the same business day once the Interac e-Transfer is verified and most arrive within 2 to 5 business days. pepuro ships within Canada only.

Your Questions,
Answered
Frequently asked questions
What does "for research use only" actually mean?
Every peptide we sell is supplied strictly for in-vitro and laboratory research. Our products are not intended for human consumption, diagnosis, or treatment of any condition. Researchers are responsible for handling and use in compliance with their institution's rules.
Are these products Health Canada approved?
No. Research peptides are not registered as consumer health products in Canada. They are research chemicals, sold only for laboratory use. We do not make health claims and do not provide medical or regulatory advice.
How do I verify the quality of a vial?
Every vial ships with a unique QR code. Scan it to pull up that specific batch's third-party lab report - purity, mass spec, and identity.
How do you ship, and is the packaging discreet?
Orders ship from our distribution centers in Calgary, Toronto and Vancouver via Canada Post in plain, unbranded packaging with no product references on the outside. We pack Same business day once your e-Transfer is verified; payments verified after 2 pm MT ship the next business day, and most domestic orders then arrive 2-5 business days in transit for most Canadian addresses. A tracking number is emailed to you when it leaves us.
Which payment methods do you accept?
We use Interac e-Transfer for all orders. After checkout, you'll receive a reference number and the e-Transfer email. Your order is confirmed once payment is received.
Do you ship to every province and territory?
Yes - shipping is free anywhere in Canada.
How should peptides be stored on arrival?
Unreconstituted vials are typically stored refrigerated; once reconstituted, refrigerate and use within the timeframe noted on the batch's lab documentation. Always defer to the specific peptide's research literature.
What's your return policy?
Because of the nature of research peptides, we do not accept returns and we do not issue refunds - product cannot be sent back once it leaves our control. The only remedy is a free replacement: if an order arrives damaged (a broken, cracked or leaking vial, or a broken seal) or is the wrong product, contact support within 7 days of delivery with photos and we will ship a replacement, with nothing to send back.
