AHK-Cu (Copper Tripeptide-3)

AHK-Cu (Copper Tripeptide-3) is a synthetic copper-binding tripeptide composed of Alanine-Histidine-Lysine complexed with a copper ion (Cu²⁺). While structurally similar to the naturally occurring GHK-Cu (differing only in the first amino acid - alanine vs glycine), AHK-Cu demonstrates targeted activity on dermal papilla cells and hair follicles. Research shows it stimulates hair follicle elongation, promotes dermal papilla cell proliferation, increases VEGF production, and inhibits TGF-β1 - making it particularly promising for hair growth applications. It also supports skin regeneration through fibroblast activation and collagen synthesis.

• Hair Growth / Hair Loss
• Skin Regeneration
• Anti-Aging

Stimulates hair follicle elongation, promotes dermal papilla cell proliferation, increases VEGF for improved scalp circulation, reduces TGF-β1 (counters DHT effects), anti-apoptotic protection for follicles, collagen synthesis support, convenient topical application

AHK-Cu penetrates the scalp to deliver copper directly to dermal papilla cells and hair follicles. It activates proliferation pathways, elevates the Bcl-2/Bax ratio (anti-apoptotic), increases VEGF production for enhanced blood flow, reduces TGF-β1 secretion, and promotes SOD production to reduce oxidative stress. These combined effects support the anagen (growth) phase and may help revive miniaturized follicles.

Research protocols from published literature — not dosing recommendations.

• GHK-Cu — Synergistic: Complementary copper peptides targeting different aspects of tissue regeneration. GHK-Cu excels at skin repair while AHK-Cu targets hair follicles. Can be combined in formulations
• Minoxidil — Synergistic: Both promote hair growth via different mechanisms - minoxidil via potassium channel opening and vasodilation, AHK-Cu via dermal papilla stimulation and VEGF. Often combined in hair loss protocols
• Finasteride / Dutasteride — Complementary: 5-alpha reductase inhibitors block DHT production while AHK-Cu may help counter DHT effects on follicles. Different mechanisms support combination approach
• Copper Supplements — Avoid Combination: Risk of copper toxicity when combined with additional copper sources. Monitor total copper intake and avoid stacking copper peptides with oral copper supplements
• BPC-157 — Compatible: Different tissue repair mechanisms - BPC-157 promotes systemic healing while AHK-Cu targets skin/hair. Safe to use in parallel for comprehensive regeneration support
• Vitamin C (L-Ascorbic Acid) — Requires Timing: Low pH of ascorbic acid can destabilize copper peptides. Use at different times - Vitamin C in morning, AHK-Cu in evening - to avoid interaction
• AHA/BHA Acids — Use Caution: Acidic exfoliants (glycolic, salicylic acid) can destabilize copper peptide complexes and reduce effectiveness. Use at different times or in separate routines
• Retinol / Retinoids — Use Caution: Both are potent actives that can cause irritation. Retinoids also lower skin pH. Introduce slowly or use at different times to avoid sensitization
• Iron Chelators — Monitor Combination: May interfere with copper binding and reduce peptide effectiveness. Monitor for reduced efficacy if using iron-chelating compounds
• Hyaluronic Acid — Synergistic: Excellent combination - hyaluronic acid provides hydration and supports peptide penetration while AHK-Cu promotes follicle and skin health

Supplies:

• AHK-Cu powder (99% purity)
• Distilled water or suitable carrier (alcohol-free)
• pH meter or strips (target pH 5.5-7.0)
• Dark glass dropper bottle for storage
• Sterile work surface
• Optional: liposomal delivery base for enhanced penetration

1. 1Calculate amount needed for desired concentration (e.g., 100mg for 1% in 10mL)
2. 2Dissolve AHK-Cu powder in distilled water or water phase of formulation
3. 3Verify pH is between 5.5-7.0 - adjust if necessary (avoid pH below 5)
4. 4Add to cool-down phase of formulation (<40°C / 104°F) - heat degrades peptide
5. 5Mix gently until fully incorporated - do not shake vigorously
6. 6Transfer to dark glass container to protect from light
7. 7Store refrigerated at 2-8°C
8. 8Use within 30 days of preparation

Week 1-2: No visible changes; peptide is working at cellular level. Week 2-4: Some users report reduced hair shedding; scalp may feel healthier. Month 1-2: Vellus (fine) hairs may begin appearing in thinning areas. Month 2-3: New growth becoming visible; existing hairs may appear thicker. Month 3-4: Noticeable improvement in hair density and quality. Month 4-6: Significant results visible; continued improvement expected. Month 6-12: Full results achieved with consistent use. For skin: Improvements in texture and firmness may be noticed within 4-8 weeks.

Generally well-tolerated with excellent safety profile in topical applications. Avoid use with acidic products (AHAs, BHAs, Vitamin C) - use at different times. Do not combine with additional copper supplements - risk of copper toxicity. Keep pH between 5.5-7.0 for stability and skin compatibility. Store properly - degrades with heat, light, and improper pH. Patch test before full application if sensitive skin. Discontinue if irritation, redness, or itching persists. Not for use on broken or infected skin. Avoid eye area - may cause irritation. Limited long-term safety data - use as directed.
