Copper Peptide Overview:

AHK-CU + GHK-CU

This is the first spray formulated to feature AHK-Cu as the primary copper peptide, selected for its targeted role in hair and scalp applications. AHK-Cu is a synthetic copper peptide specifically designed to interact at the hair follicle level and has been studied for its activity around dermal papilla cells and follicle signaling. Research suggests AHK-Cu tripeptide may influence hair follicle elongation and cellular activity associated with hair cycling (1).

GHK-Cu is included in a supporting role to complement the formula. While GHK-Cu occurs naturally in the human body, the form used in topical products is lab-synthesized for consistency and stability.

Each bottle delivers 2400mg of AHK-Cu and 2400mg of GHK-Cu in a 1:1 ratio, suspended only in distilled water. The formula contains no fragrances, dyes, or additional actives.

Our hair spray is third-party tested and verified at 99 percent purity using in-house HPLC analysis.

Is it legal to take AHK-Cu Peptides??

Yes, both AHK-Cu peptides are legal to take and safe to use in topical serum formulations like this one.

Are there any side effects?

No known side effects when used as directed. Avoid overuse or applying to broken skin.

Has anyone tried combining GHK-Cu and AHK-Cu?

Combining both is extremely rare, this is the first known product (from Neurogan Health) to deliver them together in a 1:1 topical spray.

How much am I getting per spray?

Each spray delivers an estimated dose with a 1:1 ratio of GHK-Cu to AHK-Cu, though exact mg per spray may vary slightly due to the spray cap.

What is AHK-Cu used for?

AHK-Cu is a synthetic copper peptide used primarily in hair and scalp formulations. It is designed to interact locally at the hair follicle level and has been studied for its role in follicle signaling and dermal papilla cell activity, which are involved in the hair growth cycle.

How long does AHK-Cu take to work?

Based on our testing and feedback from people in our network, results vary, but most users begin evaluating changes within 4–8 weeks, with more noticeable differences often appearing after 2–3 months of consistent use. Here is what one customer said: “Within about one month, I could actually see a difference in real hair growth and less breakage. It has only been two months so far.”

How do you use AHK-Cu for hair growth?

Pull your hair back and apply one spray to each side of the thinning area and one spray to the back of the scalp, then massage it in before it drips. Use once in the morning and once at night, and allow 4–8 weeks of consistent use to begin evaluating changes, with results commonly assessed after 2–3 months.

    Copper peptide hair serum delivers quality and on it's promises

    I stumbled upon the use of copper peptides and had exhausted using a multitude of other pre-made oils and mixtures to no avail on my hair/scalp. I looked into many other companies and what copper peptides they offered and while there are much cheaper options on the market from other companies, when you account for the cost of the copper peptides at the alleged concentrations they are marketed, it begins to make you suspicious of the quality and whether you are getting you're buying. Neurogan offers lab-tested results affirming the purity and is GMP certified providing assurance you are buying the copper peptides in the highest quality.

    I am nearing the end of month two of using the product. I've opted to use it twice a day and I am a bit liberal with the # of sprays/areas i use it, so I'm on my 2nd bottle, but with more conservative sprays you can easily get more than a month even using it twice a day, and using it once a day extends that even further. While I'm only on the second month, so too soon to say how much an effect it has had on longer term growth, I have noticed a decrease in hair fall, my hair grows quicker, and my scalp feels healthier. All of these things have lead to it appearing thicker and I have finally started to see smaller hairs coming in, in the spots that previously were a bit more sparse including the widening of my hair part beginning to recover. I'm looking forward to what the end of the third and fourth month will look like at this rate. As an…

    It works

    I’m currently on my second bottle and I’ve noticed my hair seems thicker and I can't wait to see the results after a few more months.

    First bottle

    I use to struggle with scalp irritation and this serum has definitely improved my scalp health. It also feels like my hair is growing faster.

    AHK-CU + GHK-CU Hair Serum Pro

    I was very skeptical buying this spray, especially because it's pricey and didn't know if it would do anything. I've been suffering with male pattern baldness for the past 4-5 years and have tried everything from minoxidil, Finasteride, microderm rolling, stem cell injections and FUE. Nothing has worked at all. I started a regimen of 5mg of oral GHK-CU 2 x daily and AHK-CU + GHK-CU Hair Serum Pro topically 2 x daily. Within 1 month I could actually see a difference in actual hair growth and less breakage. It's only been 2 months since I've started this and I have stopped using the Minoxidil foam and only use the AHK-CU + GHK-CU Hair Serum Pro.

    Turned scalp blue and nothing else

    I’ve been using this every day for a month and it stains my scalp blue. No other ghkcu products have done this. I use topical ghkcu face cream from another company that has blue color but doesn’t stain my face. Zero change to hair.
