SHLP2 vs Palmitoyl Tripeptide-1
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 →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 | SHLP2 | Palmitoyl Tripeptide-1 |
|---|---|---|
| Mechanism | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. | 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 | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. |
| Administration | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. |
| Side Effects | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. | Very well-tolerated. Suitable for most skin types including sensitive skin. |
