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.
Elevate hair and skin vitality from the root. AHK-Cu is a copper-binding peptide studied for its potential to support hair growth, strengthen follicles, encourage collagen production, and promote healthier-looking skin. Its regenerative focus makes it a standout for improving density, resilience, and overall appearance.
AHK-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.
AHK-Cu is a copper complex of the tripeptide Ala-His-Lys. Because copper-complex and salt representations vary, a universal AHK-Cu 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 AHK-CU is, how it works, and why it is being studied.
AHK-Cu is best known for hair-follicle and thinning-hair research. It is the copper peptide people find when they want to focus more on hair support than skin.
AHK-Cu is a copper-binding tripeptide studied in human hair-follicle explants and dermal papilla cells. Its strongest direct evidence is laboratory/ex-vivo rather than large clinical hair-loss trials. [1]
Hair grows from living follicles, and those follicles depend on healthy support cells. Laboratory research connecting AHK-Cu with human follicles is what made it so interesting in the hair conversation.
AHK-Cu increased elongation of human hair follicles ex vivo and proliferation of cultured dermal papilla cells in a published study. Those findings support follicle research interest but do not establish clinical regrowth in people with androgenetic alopecia. [1]
Think of each follicle as a tiny factory. If the cells around it are not functioning well, production may slow; AHK-Cu is studied for how it interacts with that factory and its support crew.
Dermal papilla cells help regulate follicle growth cycling and signalling. AHK-Cu research examines effects on those support cells and follicle tissue rather than simply coating the hair shaft. [1]
That is too strong a promise. Its appeal is supporting follicle biology that is still active, not magically rebuilding every follicle that has stopped functioning.
That claim goes beyond the evidence. Ex-vivo follicle elongation and cell-culture effects do not demonstrate regeneration of permanently lost follicles in humans. [1]
Hair is its main claim to fame. Copper peptides share repair-related biology, but GHK-Cu is usually the name people choose when skin and collagen are the main interest.
AHK-Cu’s best-known direct study focuses on hair follicles and dermal papilla cells. Copper-peptide biology overlaps with tissue-remodelling research, but hair is the more specific evidence theme for AHK-Cu. [1]
They are related copper peptides with slightly different structures. AHK-Cu leans toward hair-follicle research; GHK-Cu is much better known for skin, collagen, and broader tissue renewal.
The two tripeptides have different amino-acid sequences and different literature footprints. AHK-Cu has notable hair-follicle work; GHK-Cu has broader research around fibroblasts, collagen and tissue remodelling. [1]
No. Minoxidil is a finished drug with a specific clinical use. AHK-Cu is an experimental copper peptide explored for its interaction with follicles and the cells surrounding them.
No. Minoxidil has a distinct pharmacology and clinical evidence base for hair loss. AHK-Cu is an experimental copper peptide with laboratory/ex-vivo follicle evidence, so the two should not be presented as equivalent. [1]
It offers a more focused copper-peptide option for people whose main research interest is hair rather than an all-purpose skin or recovery blend.
Its research appeal is specificity: it offers a defined copper-peptide model for studying follicle and dermal-papilla biology. That is a research distinction, not proof of superior clinical hair growth. [1]

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.
