Substance P vs BPC-157
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Substance P
Substance P is an 11-amino acid neuropeptide involved in pain transmission, inflammation, and various neurological processes. While not used therapeutically itself, understanding it is crucial for pain research.

| Aspect | Substance P | BPC-157 |
|---|---|---|
| Mechanism | Binds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells. | 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 | Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea. | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. |
| Administration | Research compound only. Therapeutic applications focus on blocking rather than administering Substance P. | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. |
| Side Effects | Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically. | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. |
