SHLP2 vs Matrixyl
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
SHLP2
SHLP2 (Small Humanin-Like Peptide 2) is a mitochondrial-derived peptide similar to humanin. It has shown insulin-sensitizing and cytoprotective effects in research, with potential metabolic benefits.
Full details →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.
Full details →Side-by-Side Comparison
| Aspect | SHLP2 | Matrixyl |
|---|---|---|
| Mechanism | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. | Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage. |
| Typical Dosage | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. | Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects. |
| Administration | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. | Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides. |
| Side Effects | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. | Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types. |
