| Aspect | PE-22-28 | BPC-157 |
|---|---|---|
| Mechanism | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. | 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. |
| Typical Dosage | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. |
| Administration | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. |
| Side Effects | Very limited human data. Primarily studied in animal models for safety and efficacy. | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. |
