Argireline vs SHLP2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Argireline
Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.

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 | Argireline | SHLP2 |
|---|---|---|
| Dose Range | 500 mcg–1 mg | 1 mg–5 mg |
| Frequency | 2x daily | 1x daily |
| Cycle Length | 4–8 weeks | 4–8 weeks |
| Route | topical | subcutaneous |
| Mechanism | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. |
| Typical Dosage | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. |
| Administration | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. |
| Side Effects | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. |
