| Aspect | BPC-157 | AHK-Cu |
|---|---|---|
| Mechanism | BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels. | 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 | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. |
| Administration | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. | 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 | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. |
