Substance P vs Epitalon
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.
Full details →Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →Side-by-Side Comparison
| Aspect | Substance P | Epitalon |
|---|---|---|
| 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. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Research compound only. Therapeutic applications focus on blocking rather than administering Substance P. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically. | Generally well-tolerated. May affect sleep patterns initially. |
