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