Dermal & melanocortin signalling
Skin Peptides in Canada
4 compounds in stock
The skin category covers two unrelated mechanisms: copper-peptide signalling studied around extracellular matrix remodelling, and melanocortin receptor agonism studied around pigmentation. The blends in this category combine dermal compounds with repair peptides, which is why their composition is worth reading before choosing one. Priced and shipped in CAD, for laboratory and research use only.

GHK-Cu and copper-peptide research
GHK-Cu is a naturally occurring copper-binding tripeptide, one of the most-studied compounds in dermal research. Interest centres on extracellular matrix remodelling and collagen signalling. It is the anchor compound for this category and appears in both blends below — see GHK-Cu dosage for handling specifics, noting that copper peptides have reconstitution considerations the standard guides don't cover.
GLOW and KLOW blends
The blends are where this category overlaps with recovery. GLOW combines GHK-Cu with BPC-157 and TB-500. KLOW adds KPV to that base, bringing the anti-inflammatory α-MSH pathway in. Both are single vials rather than separate compounds, so read the composition before assuming equivalence with the standalone products.
Melanocortin agonists
Melanotan 2 is a non-selective melanocortin receptor agonist studied around melanogenesis — a completely different mechanism from the copper peptides above. Because it is non-selective it also engages MC4R, which is why PT-141, a related melanocortin compound, sits in the foundational category. Melanocyte and skin peptides is the category primer.

Skin peptides FAQ
- What is GHK-Cu?
- GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper). It is studied in dermal research contexts around extracellular matrix remodelling and collagen signalling.
- What is the difference between GLOW and KLOW?
- GLOW combines GHK-Cu with BPC-157 and TB-500. KLOW adds KPV to that base, bringing an anti-inflammatory α-MSH pathway into the blend. Both are supplied as single vials.
- Can I buy GHK-Cu in Canada?
- Yes. Research-grade GHK-Cu is available from Canada Peptides, standalone and within the GLOW and KLOW blends, priced in CAD and shipped within Canada, for research use only.
- How is Melanotan 2 different from GHK-Cu?
- Entirely different mechanisms. GHK-Cu is a copper-binding tripeptide studied around matrix remodelling. Melanotan 2 is a non-selective melanocortin receptor agonist studied around melanogenesis. They share a category label, not a pathway.
- Are skin peptides research use only?
- Yes. Everything in this category is supplied strictly for laboratory and research use. Nothing on this page is medical advice, a cosmetic claim, or a therapeutic claim.
