Substance P vs Palmitoyl Tripeptide-1
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 →Palmitoyl Tripeptide-1
Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide that stimulates collagen production. It's one of two peptides in the Matrixyl 3000 complex, working synergistically with Palmitoyl Tetrapeptide-7.
Full details →Side-by-Side Comparison
| Aspect | Substance P | Palmitoyl Tripeptide-1 |
|---|---|---|
| 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. | Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components. |
| Typical Dosage | Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea. | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. |
| Administration | Research compound only. Therapeutic applications focus on blocking rather than administering Substance P. | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. |
| Side Effects | Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically. | Very well-tolerated. Suitable for most skin types including sensitive skin. |
