AHK-Cu (Alanine-Histidine-Lysine Copper) is a tripeptide copper complex that targets hair follicle regeneration directly. Not your hormones. Not your immune system. Your follicles.
We pair it with GHK-Cu, which handles tissue repair and collagen production. At the molecular level, AHK-Cu also increases VEGF (vascular endothelial growth factor) production to improve scalp blood flow, and upregulates SOD (superoxide dismutase) to reduce the oxidative stress that triggers DHT-driven follicle miniaturization — one of the primary mechanisms behind androgenetic alopecia.
What Copper Peptides Do
AHK-Cu targets follicles at the cellular level. No hormone manipulation. No immune suppression. Just direct stimulation.
AHK-Cu activates dermal papilla cells — the cells that actually control whether hair grows or doesn't. It also boosts VEGF (vascular endothelial growth factor), improving blood flow and nutrient delivery to active follicles.
Keeps follicles in the anagen (growth) phase of the hair growth cycle longer, delaying the transition to the telogen (resting) phase — so each strand has more time to thicken.
GHK-Cu repairs damaged tissue and boosts collagen. You can't grow hair in a damaged scalp environment.
Copper peptides reduce inflammation. An irritated scalp actively works against growth.
The dual peptide formula supports fuller-looking hair. Consistently, over 2–3 months.
No sexual dysfunction. No heart palpitations. Copper peptides work through nourishment, not suppression.
Clinical Evidence
"During wound-healing studies, we noted GHK-Cu induced greatly enlarged hair follicles."

The Formula
The first spray to combine AHK-Cu and GHK-Cu in a precise 1:1 ratio. Each targets a different part of the hair growth process.
What To Expect
Scalp feel improves, less shedding. Inflammation calms down.
First new growth visible. Baby hairs along hairline and part.
Density visibly improving. Strands are thickening and lengthening.
Fuller, thicker hair. Continued improvement with consistent use.

AHK-CU + GHK-Cu Hair Elixir Expert is a precision copper peptide spray formulated for topical scalp application. Each bottle contains a combined 4,800mg of two copper tripeptide complexes dissolved in purified distilled water — nothing else.
AHK-Cu directly targets the dermal papilla cells responsible for hair follicle activation and elongation. GHK-Cu works on tissue repair and collagen synthesis, creating the scalp environment in which follicles can thrive.
Unlike DHT blockers or vasodilators, copper peptides operate through a nourishment pathway — no hormonal interference, no immune suppression.
Active Ingredients: AHK-Cu (Alanine-Histidine-Lysine-Copper) 2,400mg, GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) 2,400mg
Other Ingredients: Purified Distilled Water
No preservatives. No fragrances. No fillers. No alcohol.
Every batch is independently tested by third-party laboratories using HPLC. Our certificate of analysis confirms 99%+ peptide purity for every production run.
Apply 6–8 sprays directly to thinning areas or your entire scalp. Clean, towel-dried, or dry hair all work.
Work it into your scalp with your fingertips for 30–60 seconds. Make sure it absorbs evenly.
Once or twice a day. Most people start noticing changes around the 2–3 month mark. Consistency matters.
Apply AHK-Cu immediately after microneedling for amplified absorption. Multiple customers report significantly faster results with this combination.
Real Results
"I've done the whole list: minoxidil, finasteride, microneedling, stem cell injections, even an FUE transplant. None of it gave me real results. Within the first month on this spray I could see actual new growth and way less breakage. I dropped the minoxidil completely."
"I'm seeing tiny new hairs growing in where my part was widening. That area was basically bare before."
"On my second bottle and my hair genuinely feels and looks thicker. That's all I wanted."
"Fixed my scalp irritation in weeks. Then the hair started growing in faster. Two problems solved."
"I microneedle first and spray this on right after. The results have been wild. Non-negotiable combo."
How It Compares
Traditional hair loss solutions come with side effects because they interfere with your body's hormonal systems. AHK-Cu doesn't.

|---|---|---|---|---|---|
| Hormonal Side Effects | ✓ None | ✗ Yes | ✗ Some | ✗ Yes | ✗ Possible |
| Sexual Side Effects | ✓ None | ✗ Reported | ✓ None | ✗ Reported | ✗ Possible |

| Reported Safety | ✓ Excellent | ✗ FDA warnings | ✓ Generally safe | ✗ FDA warnings | ✓ Generally safe |
Most hair loss treatments cause side effects because they block hormones (DHT) or suppress the immune system. AHK-Cu works through a completely different mechanism: nourishing follicles, reducing inflammation, and stimulating growth factors. Zero reported hormonal side effects.
FAQ
AHK-Cu stands for Alanine-Histidine-Lysine Copper — also known by its INCI name Copper Tripeptide-3. It is a synthetic copper peptide complex that has been studied since 2007 for its ability to directly stimulate hair follicle cells, particularly the dermal papilla cells that control whether your hair grows or stays dormant. Unlike GHK-Cu (Copper Tripeptide-1), which occurs naturally in human plasma, AHK-Cu was developed specifically to target follicle regeneration.
Minoxidil is a vasodilator — it widens blood vessels to deliver more oxygen to follicles. Finasteride blocks DHT, the hormone that shrinks follicles. Both work against your body in some way. AHK-Cu is a copper peptide that directly signals dermal papilla cells to activate growth cycles. No hormonal interference, no initial shedding phase, no prescription required.
Androgenetic alopecia (pattern hair loss) is the most common form of hair loss in both men and women, driven by genetic sensitivity to DHT. AHK-Cu addresses this by working through a completely different pathway — stimulating follicle growth directly rather than blocking DHT. While copper peptides are not a replacement for medical treatment, they offer a non-hormonal approach to supporting follicle health.
Most people notice less shedding and improved scalp feel within the first 4–6 weeks. Visible new growth — baby hairs along the hairline and part — typically appears around months 2–3. Fuller, thicker hair density is usually evident by months 5–6 with consistent daily use. Hair growth is slow biology; give it the time it needs.
In clinical studies and customer reports, AHK-Cu has shown no hormonal side effects, no sexual side effects, and no immune suppression. The blue-violet color of the formula is the natural appearance of copper peptide and is not a dye — it does not stain skin or fabric when applied correctly. A small number of users with sensitive skin experience mild initial scalp tingling, which typically resolves within the first week.
Yes. AHK-Cu is suitable for both men and women experiencing hair thinning. Because it works through a nourishment pathway rather than by blocking androgens, it does not affect hormonal balance and is appropriate for female-pattern hair loss. We recommend consulting your healthcare provider if you are pregnant or nursing.
Three ingredients: AHK-Cu (Alanine-Histidine-Lysine-Copper), GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper), and distilled water. That's it. No fillers, no fragrances, no preservatives. The total peptide concentration is 4,800mg per 60mL bottle (2,400mg each). Our lab results are publicly available — we publish them because we stand behind what we make.
