Introduction to the drug AHK-CU
AHK-Cu is a copper-chelated tripeptide targeting hair follicles, a homologous derivative of GHK-Cu. Compared with classic GHK-Cu, it exhibits stronger selectivity for dermal papilla cells, making it a mainstream bioactive peptide for hair regrowth. The peptide carrier delivers bioavailable Cu²⁺ precisely into skin and follicle cells, activating copper-dependent enzymes and regulating multiple regenerative signaling pathways. It also delivers anti-aging, anti-inflammatory and antioxidant effects, widely applied in anti-hair-loss serums and rejuvenating skincare. It is a cosmetic raw material, not prescription pharmaceutical.

Mechanism of Action
- Activate core hair-growth Wnt/β-catenin signal: Bind to CTR1 transporters on dermal papilla cells, trigger proliferation & differentiation of hair follicle stem cells, reactivate miniaturized atrophic follicles.
- Upregulate VEGF (Vascular Endothelial Growth Factor): Stimulate scalp microangiogenesis, boost oxygen & nutrient supply to follicles and thicken follicle basement membrane.
- Downregulate inhibitory TGF-β1: Block androgen-induced follicular fibrosis, prevent premature catagen entry and prolong anagen (active growth phase).
- Elevate anti-apoptotic Bcl-2 ratio, suppress Caspase-3 activity to reduce follicular cell death & shedding.
- Mildly inhibit 5α-reductase to reduce scalp DHT accumulation, improve androgenic alopecia microenvironment.
Skin Anti-Aging & Repair Pathway
- Deliver bioavailable Cu²⁺: Copper acts as cofactor of lysyl oxidase, facilitating cross-linking of collagen & elastin to strengthen dermal supporting structure.
- Potently stimulate fibroblast proliferation: In vitro test shows 340% upregulation of procollagen I synthesis, superior to equal molar GHK-Cu.
- Balance MMP/TIMP matrix metabolism: Upregulate TIMP tissue inhibitor to reduce collagen degradation and increase dermal density.
- Boost glycosaminoglycan (GAG) secretion: Lock dermal moisture, plump skin and smooth fine dry lines.
- Antioxidant & anti-inflammatory: Activate SOD to neutralize free radicals, suppress pro-inflammatory TNF-α & IL-6 to relieve redness and impaired skin barrier.

Caspian G. –
This AU50 AHK-Cu is acetate buffered lyophilized copper peptide powder with HPLC purity over 99%. It features a stable 5.0–7.0 neutral pH range and forms a uniform sky-blue liquid after reconstitution. Stored steadily at 20–25°C without freezing, the copper chelate complex won’t fade or break down over weeks of cabinet storage away from strong light.
Ralph B. –
This AHK-Cu copper peptide comes as lyophilized powder with acetate buffer. HPLC testing proves purity is over 99%. After reconstitution, it forms a stable sky-blue solution with pH kept between 5.0–7.0. Stored at 20–25°C without freezing, the copper complex stays intact with no discoloration.
Briar Oakley –
This cyclic follicle-homing copper peptide expands my lab’s research scope far beyond basic topical skincare anti-aging analysis. I also utilize AU50 for in-vitro scar repair and androgenetic alopecia hair follicle culture trials, and its stable 5.0–7.0 pH range removes the extra step of mixing neutralizing buffer additives into my dermal cell culture media formulations.
Daisie Maeve –
Advanced industrial recrystallization lyophilization creates ultra-fine free-flowing lyophilized powder without hard compacted sediment chunks settled at the vial bottom. When I only require tiny microgram-level samples for early preliminary skin regeneration screening assays, I can extract partial dry powder without fully reconstituting the entire vial to conserve expensive AU50 lab stock.
Miles J. –
This AHK-CU copper peptide is lyophilized powder with acetate buffering. After reconstitution, it forms a beautiful sky-blue liquid. HPLC testing shows purity tops 99%. Maintained between pH 5.0–7.0 and stored at room temperature without freezing, the copper complex stays chemically stable with no color fading for many weeks.
Willa G. –
The 50mg vial size works great for my formulation research, so I never waste leftover reconstituted material. The buffered pH prevents the copper peptide from breaking down prematurely. This bulk pack offers excellent cost savings for long-term anti-aging study projects.

I conduct random blind HPLC spot quality audits on randomly selected vials from every shipment batch, every tested sample consistently hits the advertised ≥99% purity threshold with no unknown impurity peaks visible on chromatogram outputs. Complete batch purity certification documents ship alongside every order, fully compliant for university cosmetic science lab audit and academic research manuscript submission standards.
Elias I. –
As a cyclic homing peptide with follicle affinity, this AHK-Cu is my core raw material for hair follicle regeneration and anti-aging skincare research. Its physiological pH perfectly matches skin tissue conditions, and reconstituted sky-blue solution stays transparent for multiple refrigerated days. All vials arrived fully intact during cross-border shipping.
Seth Rowe –
The optimized acetate buffer lyophilization process drastically minimizes copper-peptide adhesion to inner glass vial walls after dissolution. I recover nearly 100% of the labeled 50mg lyophilized powder mass from every vial, removing major dosing inaccuracies in quantitative fibroblast receptor binding and skin anti-aging signaling research.
Freya J. –
The CAS number, molecular formula and 412.0 G/Mol molecular weight fully match official biochemical datasheets. This research-grade copper tripeptide contains no bulking fillers or degraded peptide fragments, and room-temperature storage eliminates freeze-thaw damage to the fragile copper chelate structure.
Galen K. –
I’ve tested multiple copper peptide variants side-by-side for comparative cosmetic research, and this AHK-Cu retains its signature sky-blue tone far longer than competing products. Gentle slow swirling achieves full dissolution without splitting the copper-peptide chelate bond that delivers follicle-targeted activity.
Stella Rhea –
I ran blinded parallel dermal regeneration cell trials with AHK-Cu sourced from six different manufacturers, and this acetate co-lyophilized AU50 variant delivers unmatched uniform solubility with barely any powder residue sticking to inner glass vial walls. Slow circular swirling achieves full dissolution; harsh vigorous shaking destabilizes the copper chelate and invalidates quantitative collagen production assay readouts.
Nadine K. –
Every vial in the 10-piece pack delivers identical powder quality. There are zero inconsistencies in color and concentration across the batch. The powder dissolves fully without solid residue, and the sealed vial keeps out moisture so the lyophilized material never clumps up during long-term ambient storage.

Consistent certified ≥99% HPLC purity, unique controlled room-temperature (20–25°C, no freezing) storage requirements, three flexible vial dosage sizes and rock-solid cross-batch uniformity make AU50 my exclusive AHK-Cu copper peptide supplier. I place monthly recurring bulk restock orders for my long-term collagen synthesis, scalp follicle regeneration and cosmetic anti-aging lab research projects, with zero fluctuation in powder solubility or follicle-targeted biological activity between every shipment when stored correctly.
Wesley Kade –
International bulk shipping packaging uses custom individual shock-absorbent foam dividers to isolate each glass vial and prevent collision breakage during long overseas transit. All shipments are temperature-controlled during delivery to maintain the required 20–25°C storage range, and zero vials arrived cracked, chipped, leaking or contaminated upon delivery to my dermatology research facility.
Quinn N. –
I have sourced multiple copper tripeptides for cosmetic testing, and this AHK-CU holds its blue color far better than other variants. The lyophilized powder stays loose, and gentle swirling is all you need to get a uniform blue solution without damaging the peptide structure.
Sterling P. –
This bulk 10-vial kit brings down the cost of my cosmetic research significantly. Vial-to-vial uniformity is excellent, so the shade of blue stays consistent across all my test batches. This will be my regular reorder for follicle-targeted peptide studies.
Pearl M. –
The molecular formula and 412.0 g/mol molecular weight match the technical datasheet perfectly. This research-grade raw material contains no extra fillers or impurities. Keeping it at 20–25°C without freezing prevents breakdown of the copper complex completely.
Rae O. –
The 50mg vial capacity works great for my bulk formulation trials. I only reconstitute the amount I need each time, so I avoid wasting mixed peptide. The steady 5.0–7.0 pH range prevents the copper complex from dissociating prematurely.
Cedric Oakley –
This 10-vial bulk pack includes a steep limited-time promotional markdown that drastically cuts my monthly lab raw material procurement overhead. Vial-to-vial powder texture, copper-peptide concentration and HPLC purity show zero measurable deviation, making all my anti-aging and follicle regeneration experimental data highly repeatable across separate test batches.
Una Quinton –
A new lab intern accidentally placed an unopened AU50 AHK-Cu vial into the -20°C freezer for two full days by mistake. Post-testing revealed irreversible breakdown of the copper-peptide chelate bond, faded sky-blue reconstitution color and nearly complete loss of collagen-stimulating follicle regenerative activity, reinforcing the non-negotiable rule that this copper peptide cannot be frozen and requires controlled 20–25°C dark storage at all times.
Sterling P. –
The lyophilized powder flows freely inside each vial and will not absorb ambient moisture. The acetate buffer maintains a stable pH environment, effectively preventing the copper peptide complex from decomposing. After mixing, the sky-blue tone remains consistent, with no fading or turbidity even after days of refrigeration.
Finley Maeve –
Each vial inside the standard 50mg×10 bulk kit holds fine uniform lyophilized powder that dissolves fully into characteristic sky-blue particle-free aqueous liquid after slow gentle swirling. The airtight gold aluminum flip cap forms a complete moisture barrier, so powder never clumps or loses copper complex stability even after repeated syringe punctures to draw tiny partial aliquots for dermal fibroblast and hair follicle cell culture testing.
Kinsley O. –
Glass wall adhesion is extremely minimal thanks to the optimized acetate buffer blend. I recover nearly the full volume of lyophilized powder from each vial, ensuring precise, uniform copper peptide dosing across all my follicle regeneration in vitro test groups.
Ruth Maeve –
Prolonged UV light exposure triggers gradual discoloration and breakdown of the AHK-Cu copper chelate complex, so I store all unopened sealed vials inside fully opaque cabinet bins kept strictly between 20–25°C. After two full months of undisturbed room-temperature dark storage, the powder remains uniform off-white lyophilized solid, and reconstituted sky-blue liquid never fades or forms solid precipitates over multi-day refrigerated testing cycles.
Harlan Kade –
Three flexible dosage specifications (20mg, 50mg, 100mg per vial) fully cover all stages of my dermatology research workflow. The standard 50mg single vial fill size is calibrated for medium-scale in-vivo skin and hair follicle regeneration trials; I only reconstitute a single vial per testing cycle to eliminate waste of diluted sky-blue AHK-Cu solution that rapidly loses copper complex potency once exposed to direct sunlight.
Jasper N. –
Storing sealed vials inside opaque dark cabinets blocks UV light-induced discoloration, the primary cause of copper peptide fading. The lyophilized powder resists moisture absorption entirely, and reconstituted sky-blue liquid never develops cloudiness or solid precipitates after days of cold storage.
Owen L. –
This cyclic carrier peptide is perfect for hair follicle and skin anti-aging formulation research. The buffered pH protects the copper-peptide bond, so the blue solution remains clear and stable for days after mixing. Packaging was well cushioned, and no glass vials arrived cracked or leaking.

The airtight gold crimp stopper blocks ambient humidity completely, so the powder never clumps even after repeated brief openings to take partial samples for cosmetic formulation trials.
Marnie Rowe –
AHK-Cu is my core research compound for skin wound repair, collagen synthesis, scalp follicle regeneration and anti-aging dermatology pathway studies. Its balanced pH range of 5.0–7.0 locks the copper-peptide chelate structure intact post-reconstitution, and diluted working sky-blue solution stays uniform without precipitation for multiple refrigerated testing cycles. All glass vials arrived fully intact with zero breakage during cross-border international lab shipping.
Hilda L. –
Three volume options (20mg, 50mg, 100mg) fit all my batch sizes perfectly. The 50mg single vial fill size is ideal for mid-scale hair repair serum trials; I only reconstitute powder as needed per formulation round to avoid wasting mixed peptide that loses chelate stability over time.
Ursula E. –
Molecular weight and chemical formula match the official specifications perfectly. This research-grade complex has zero extra fillers. As long as I avoid freezing, the peptide activity stays consistent month after month with no degradation.
Elara Oakley –
This AU50 AHK-Cu copper peptide is acetate-buffered lyophilized powder with ≥99% HPLC purity, formulated as L-Alanyl-L-Histidyl-L-Lysine copper complex. Unlike most research peptides, it requires sealed vial storage at 20–25°C and must never be frozen—freezing breaks the copper-peptide chelate bond and ruins its follicle-targeted regenerative activity. Dark ambient storage blocks light degradation, preserving stable skin repair and hair follicle signaling performance for cosmetic anti-aging lab research over months.
Linden P. –
Consistent ≥99% HPLC purity, stable sky-blue chelate color, follicle-targeted cyclic peptide structure and reliable cross-batch uniformity make AU50 my permanent go-to AHK-Cu supply.
