Cagrilintide vs LL-37 (Cathelicidin)
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.

LL-37 is the only human cathelicidin antimicrobial peptide. It plays crucial roles in innate immunity and has shown diverse biological activities including antimicrobial, immunomodulatory, and wound healing properties.
Full details →Side-by-Side Comparison
| Aspect | Cagrilintide | LL-37 (Cathelicidin) |
|---|---|---|
| Mechanism | Activates 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. | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. |
| Typical Dosage | Clinical trials: 2.4mg weekly as monotherapy or in combination with semaglutide 2.4mg (CagriSema). Optimal dosing still being determined. | Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. |
| Administration | Subcutaneous injection once weekly. Currently only available in clinical trials - not yet FDA approved. | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. |
| Side Effects | Nausea, vomiting, diarrhea, constipation similar to other incretin-based therapies. Combination with semaglutide may increase GI effects initially. | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. |
