Leuphasyl vs SHLP2

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Leuphasyl

Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.

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.

Side-by-Side Comparison

AspectLeuphasylSHLP2
MechanismMimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity.Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways.
Typical DosageTopical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides.Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established.
AdministrationTopical application to expression lines. Best results with consistent twice-daily use over 8+ weeks.Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties.
Side EffectsVery well-tolerated topically. No significant adverse effects reported at cosmetic concentrations.Limited data. Animal studies suggest good tolerability. May affect glucose metabolism.
