FGL vs SHLP2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
FGL
FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.
Full details →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 →Side-by-Side Comparison
| Aspect | FGL | SHLP2 |
|---|---|---|
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. |
| Typical Dosage | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. |
| Administration | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. |
| Side Effects | Limited human data available. Animal studies show good tolerability. | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. |
