AHK-Cu vs TB-500
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
AHK-Cu
AHK-Cu (Copper Tripeptide-3, Alanine-Histidine-Lysine Copper) is a copper peptide similar to GHK-Cu but with different properties. It's used for hair growth and skin rejuvenation applications.

| Aspect | AHK-Cu | TB-500 |
|---|---|---|
| Mechanism | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. |
| Typical Dosage | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | May cause temporary fatigue, headache, or localized irritation at injection sites. |
