Palmitoyl Tetrapeptide-7 vs Substance P

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Palmitoyl Tetrapeptide-7

Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.

Side-by-Side Comparison

AspectPalmitoyl Tetrapeptide-7Substance P
MechanismSuppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides.Binds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells.
Typical DosageTopical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex.Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea.
AdministrationTopical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin.Research compound only. Therapeutic applications focus on blocking rather than administering Substance P.
Side EffectsExcellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin.Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically.
