| Aspect | BPC-157 | Cortexin |
|---|---|---|
| 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. | Contains a mixture of neuropeptides and amino acids that support neuronal metabolism, provide neuroprotection, and enhance synaptic transmission. Specific mechanisms not fully characterized. |
| Typical Dosage | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. | Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval. |
| Administration | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. | Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously. |
| Side Effects | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. | Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals. |
