Matrixyl vs TB-500
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Matrixyl
Matrixyl (Palmitoyl Pentapeptide-4) is a signal peptide that stimulates collagen and extracellular matrix production. It is one of the most well-studied anti-aging peptides with proven efficacy for wrinkle reduction.

| Aspect | Matrixyl | TB-500 |
|---|---|---|
| Mechanism | Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage. | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. |
| Typical Dosage | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. | Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. |
| Administration | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. |
| Side Effects | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. | May cause temporary fatigue, headache, or localized irritation at injection sites. |
