- Matrixyl 3000 is not a single compound but a commercial combination of two palmitoylated peptides: - Palmitoyl tripeptide-1 (Pal-GHK): Shares GHK sequence, fatty acid modified - Palmitoyl tetrapeptide-7 (Pal-GQPR): Targets IL-6 and inflammatory pathways
- When comparing GHK-Cu with Matrixyl 3000 in research, it is important to specify which component of Matrixyl 3000 is being compared, since the two components have different mechanisms.
