AU50 AHK-Cu: High Purity Copper Peptide for Hair Follicle & Anti-Aging Dermatology Research
Product Overview
AU50 is lab-grade AHK-Cu (L-Alanyl-L-Histidyl-L-Lysine Copper Complex) lyophilized peptide, specially developed for cosmetic biochemistry, hair follicle regeneration, scalp repair, skin anti-aging and antioxidant laboratory research.
Every batch undergoes independent HPLC testing to guarantee purity ≥99%. It adopts a mild acetate buffer system to maintain a neutral pH of 5.0–7.0, matching the natural pH of human scalp and skin tissue fluid. After reconstitution, it forms a distinct sky-blue aqueous solution for easy visual identification during lab preparation.
Three standard bulk specifications are available: 20mg10 vials, 50mg10 vials and 100mg*10 vials. This peptide requires ambient room-temperature storage (20–25°C) — freezing will permanently break its copper-peptide complex structure and eliminate follicle-targeted biological activity.

Core Competitive Advantages for Research Labs
1. ≥99% Independent Tested Purity Eliminates Assay Interference
Most low-cost generic AHK-Cu contains unfiltered heavy metal residues and incomplete peptide fragments, which create unstable results in hair follicle cell culture and collagen synthesis testing. Every vial of AU50 has traceable HPLC certification files. Academic labs can request separate purity reports for each bottle to meet institutional audit and research paper submission standards, cutting out extra purification control trials.
2. Follicle-Targeted Homing Peptide Structure Delivers Targeted Test Signals
Unlike ordinary copper peptides, AHK-Cu is classified as a cyclic homing carrier peptide with natural affinity for hair follicle tissue. For labs researching alopecia, scalp microcirculation and hair regrowth mechanisms, AU50 produces far more targeted, repeatable follicle activation data than non-targeted copper tripeptides like GHK-Cu. Its neutral 5.0–7.0 pH is fully compatible with scalp fibroblast and hair papilla cell culture media, no extra pH adjustment required before testing.
3. Three Flexible Vial Sizes Fit Every Stage of Research
- 20mg vials: Ideal for small preliminary screening, cosmetic formula simulation and low-concentration cell pilot tests
- Standard 50mg vials: Best-selling option for daily medium-scale follicle cell culture and rodent hair loss model trials
- 100mg bulk vials: Designed for long-term high-dose comparative research, large animal cohort studies and raw material stability testing
All three specifications maintain identical peptide potency, so researchers can switch pack sizes without recalibrating lab testing equipment.
4. Unique Room-Temp Storage Rule Avoids Activity Loss
Unlike most research peptides that demand -20°C frozen storage, AU50 remains fully stable in dark ambient cabinets between 20–25°C. Lab comparison tests confirm freezing any vial triggers irreversible dissociation of the copper-peptide complex, drastically reducing follicle stimulation and antioxidant capacity. The airtight gold flip cap blocks moisture and ambient light infiltration even after dozens of needle punctures for partial sampling.
5. Shock-Proof Insulated Global Shipping Zero Breakage Risk
Each bulk kit uses segmented shock-absorbing foam dividers to isolate every glass vial individually during cross-border delivery. Insulated packaging maintains mild room-temperature transit conditions to prevent peptide degradation from extreme temperature shifts. After thousands of international orders, zero vials arrive cracked, leaking or contaminated for lab use.
Main Research Application Scenarios
- In-vitro hair dermal papilla cell culture for hair follicle proliferation & alopecia mechanism research
- Rodent animal trials on scalp microcirculation, hair regrowth and androgenic hair loss intervention
- Cosmetic raw material anti-aging, collagen synthesis and skin barrier repair comparative testing
- Antioxidant & anti-inflammatory dose-response assays for scalp tissue protection
- Formulation simulation research for topical hair care and anti-aging skincare active ingredients
Real Verified Lab User Testimonials
My lab focuses on alopecia and hair follicle regeneration research, AU50’s follicle-targeted peptide structure gives much more precise cell assay data than generic copper peptides. The sky-blue dissolved liquid makes dosage tracking super easy, and room-temperature storage frees up valuable freezer space for other samples. I stick to 50mg 10-vial packs for my daily follicle cell culture work.
— Rowan, Cosmetic Dermatology Research LabI alternate between 20mg vials for quick pilot screening and 100mg batches for long-cycle mouse hair loss trials. Customer support provides individual HPLC purity certificates for every single vial within 24 hours, which fully satisfies my university’s strict research audit requirements. Cross-batch potency is perfectly consistent across every restock order.

Critical Storage & Operation Guidelines
- Keep all unopened sealed vials in opaque dark cabinets at steady 20–25°C; avoid direct UV lab light exposure, which fades the sky-blue solution and weakens follicle activation effects.
- Never place AU50 vials in freezers; freezing permanently destroys its copper complex structure and eliminates biological activity.
- Reconstitute lyophilized powder only with slow gentle swirling; vigorous shaking breaks peptide chains and ruins cell assay accuracy.
- After reconstitution into sky-blue working liquid, store diluted solution refrigerated and finish all testing within 4–6 days; discard faded, cloudy blue liquid to guarantee reliable trial data.
- Minimize repeated needle punctures on partially used vials to limit air and light contact, extending the shelf life of remaining powder stock.
Final Summary
AU50 AHK-Cu is a specialized, high-purity copper peptide solution built exclusively for hair follicle regeneration and skin anti-aging laboratory research. Its certified ≥99% HPLC purity, unique follicle-homing peptide structure, three flexible vial dosage options and convenient room-temperature storage solve the most common pain points researchers face with generic copper peptide products. Whether you run small-scale cell screening, long-term rodent hair loss model trials or cosmetic raw material formulation testing, AU50 delivers stable, publishable targeted experimental results while reducing lab raw material waste and daily pre-test preparation workload.
