mechanism
How it works.
GHK-Cu is a naturally occurring copper-binding tripeptide* (glycyl-L-histidyl-L-lysine) that declines with age in human plasma. Preclinical research has explored its role in fibroblast activation, collagen and glycosaminoglycan synthesis, and copper ion transport into dermal tissue.
- ↳Gly-His-Lys + Cu²⁺
Beyond dermal applications, studies have investigated GHK-Cu for wound repair and gene-regulatory activity, with transcriptomic work suggesting it may modulate hundreds of genes* related to tissue remodelling.
- ↳Pickart 2018 — ~4192 up/down
At clinical dosing* — the range used in peer-reviewed research rather than cosmetic formulation — GHK-Cu sits at an entirely different concentration than serums labelled with the same peptide.

GHK-Cu · common questions
Questions, answered.
What is the difference between the 50mg and 100mg GHK-Cu vials?
Only the amount of material. Both hold the same compound from the same synthesis and testing process. The 100mg vial is $84.99 against $54.99 for 50mg, so each milligram costs about 23% less ($0.85 vs $1.10).
Read the guide: GHK-Cu 50mg vs 100mg →Why is GHK-Cu blue?
The colour comes from the copper. GHK binds a copper ion, and the copper complex absorbs light in a way that makes it look blue. Colour shows copper is present; it is not a test of purity or identity.
Read the guide: GHK-Cu 50mg vs 100mg →How is GHK-Cu different from GLOW?
GHK-Cu is a single compound in its own vial. GLOW is a 70mg blend that contains GHK-Cu together with BPC-157 and TB-500 in one vial.
Read the guide: GLOW vs GHK-Cu →What form does GHK-Cu come in?
A lyophilized (freeze-dried) powder in a sealed vial labelled with its lot code and expiration date. Freeze-drying removes the water, which keeps the peptide stable in storage.
Read the guide: What does lyophilized mean? →How should GHK-Cu be stored?
Keep sealed vials refrigerated at 2–8°C and away from light. Let a cold vial reach room temperature before opening it, so moisture does not condense on the powder.
Read the guide: How to store research peptides →Does GHK-Cu come with a certificate of analysis?
Each batch is tested by an independent third-party lab. The COA for your lot is available by email on request: send the lot code printed on your vial to contact@vitalitipeptide.com.
Read the guide: How to read a peptide COA →Where does GHK-Cu ship from, and how fast?
It ships from within Canada. Orders placed before 2pm EST on a weekday ship the same business day; most addresses receive them next day or in 1–2 business days, and northern or remote postal codes usually take 4–5 business days. Shipping is a $15 flat rate, free over $300; subscriptions ship for $7.50, free over $150.
Read the guide: Peptide shipping in Canada →Is GHK-Cu approved by Health Canada?
No. It is sold for laboratory research use only. It has not been evaluated or approved by Health Canada and is not for human consumption.

“Bought the 100mg size. Reconstitution instructions on the product page were specific to copper peptides which I appreciated — most generic peptide guides don’t address the colour considerations.”
Natalia G · Montreal✓ verified
“Shipping was discreet, vial sealed correctly. Wish the product page had a side-by-side comparison with the GLOW formula — had to email customer service to clarify the difference, which they did answer well.”
