AHK-Cu vs SHLP2
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 | SHLP2 |
|---|---|---|
| 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. | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. |
| Typical Dosage | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. |
