At Puffin Peptides, we work with an established Canadian manufacturer and handle packaging and fulfilment here in Canada. Keeping the process close to home gives us better visibility into quality, consistency, packaging, and the batches moving through our catalogue.
That means clearer product information, accessible batch documentation, responsive local support, and a more dependable ordering experience from checkout to delivery.
Our focus is simple: well-made research products, straightforward information, and reliable Canadian service.
Where regeneration meets radiance, GHK-Cu is a copper-binding peptide known for supporting skin renewal, collagen production, hair health, and tissue repair. Often featured in advanced aesthetic and wellness formulas, it is designed to help promote firmer-looking skin, stronger hair, and a more youthful, revitalized appearance.
GHK-CU is supplied as 50 mg of lyophilized powder in a sealed glass vial for laboratory research. Confirm the selected vial and batch details before preparation.
GHK-Cu is a copper complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. Published databases contain more than one stoichiometric representation of the copper complex, so salt/complex-specific formula and molecular weight are not displayed.
This 50 mg vial opens with 5 mL BAC water.
The default easy rule is 1 mg = 10 units on a U-100 syringe. Changing the water amount updates that relationship automatically.

A clear, quick look at what GHK-CU is, how it works, and why it is being studied.
GHK-Cu is the copper peptide people usually mean when talking about skin renewal, collagen, firmness, and healthy aging. Its appeal is helping skin look better by supporting the tissue underneath it.
GHK is a naturally occurring tripeptide with high affinity for copper; GHK-Cu has been studied in fibroblast activity, collagen synthesis, extracellular-matrix remodelling and wound biology. Clinical evidence varies substantially by formulation and outcome. [1–2]
Collagen is like the support frame under a mattress. When that frame is strong, skin looks firmer and smoother; when it weakens, fine lines and looseness become easier to see.
Collagen is a major structural protein in the dermal extracellular matrix and contributes to tensile strength and tissue architecture. GHK-Cu research includes effects on fibroblast activity and matrix-remodelling pathways. [1–2]
That is one of the main reasons it is studied. Its connection to collagen and tissue renewal creates interest in improving the look of texture, firmness, and fine lines over time.
Mechanistic and cosmetic literature supports interest in firmness, elasticity and photoaged skin, but modern large randomized trials are limited. The strongest evidence concerns fibroblasts, collagen and matrix remodelling rather than a guaranteed cosmetic result. [1–2]
No. Skin gets the spotlight, but GHK-Cu is also connected to wound repair and wider tissue-renewal research. The same repair biology that interests skincare researchers can matter elsewhere too.
No. GHK-Cu research extends to wound repair, angiogenesis, inflammation and extracellular-matrix remodelling. Skin appearance is one application of broader tissue-remodelling biology. [1–2]
The peptide acts like a delivery partner that binds copper and helps bring it into cellular repair processes. Think of the peptide as carrying an important tool to the repair crew.
GHK binds Cu2+ with high affinity, forming a defined complex involved in copper-dependent biological processes. Copper is a cofactor for multiple enzymes relevant to connective-tissue biology. [1–2]
No. A mineral supplement provides dietary copper. GHK-Cu is a specific copper-bound peptide studied for how it communicates with cells involved in collagen and repair.
No. Dietary copper changes systemic copper intake, while GHK-Cu is a defined copper-peptide complex studied for specific signalling and tissue-remodelling effects. [1–2]
GHK-Cu is the better-known choice for skin, collagen, and broad tissue renewal. AHK-Cu has a more specific reputation in hair-follicle research.
Both are copper-binding tripeptides, but their amino-acid sequences differ. AHK-Cu has a smaller literature with notable hair-follicle/dermal-papilla work, while GHK-Cu has broader published research around collagen, fibroblasts and tissue remodelling. [1–2]
GHK-Cu keeps the focus on the copper-peptide side. Glow and KLOW include it inside larger blends for people who also want recovery or inflammation-focused ingredients.
GHK-Cu isolates the copper-peptide variable; Glow and KLOW combine it with additional research compounds. Evidence for GHK-Cu itself should not be treated as validation of every multi-compound blend containing it. [1–2]

Nice site and helpful chat bot. I’ll be back again.
I can’t believe it but I’ve lost 30lb. It’s been 3 months and felt compelled to write a review. I know it’s not Puffin I have to thank but their site came up in google and brought me here. Thank youuuuuu! <3
Products in the same research area, each with its own pathway, evidence level and selectable strengths.

Hi! I’m Ask Puffin. I can explain peptides in plain language and help with products, prices, stock, shipping, and site questions. What can I help with?
