Cagrilintide vs Leuphasyl

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

Cagrilintide

Cagrilintide is a long-acting amylin analog in development, showing promising results when combined with semaglutide (CagriSema). Amylin is a hormone co-secreted with insulin that promotes satiety.

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.

Side-by-Side Comparison

AspectCagrilintideLeuphasyl
MechanismActivates amylin receptors (calcitonin receptor with RAMP proteins) to slow gastric emptying, suppress glucagon secretion, and reduce food intake through central satiety mechanisms distinct from GLP-1.Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity.
Typical DosageClinical trials: 2.4mg weekly as monotherapy or in combination with semaglutide 2.4mg (CagriSema). Optimal dosing still being determined.Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides.
AdministrationSubcutaneous injection once weekly. Currently only available in clinical trials - not yet FDA approved.Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks.
Side EffectsNausea, vomiting, diarrhea, constipation similar to other incretin-based therapies. Combination with semaglutide may increase GI effects initially.Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations.
