Liraglutide vs LL-37 (Cathelicidin)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Liraglutide
Liraglutide is a GLP-1 receptor agonist FDA-approved as Victoza for type 2 diabetes and Saxenda for chronic weight management. It was one of the first daily GLP-1 agonists and paved the way for newer weekly options like semaglutide.
Full details →LL-37 (Cathelicidin)
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 | Liraglutide | LL-37 (Cathelicidin) |
|---|---|---|
| Mechanism | Binds to and activates GLP-1 receptors, stimulating insulin secretion in a glucose-dependent manner, suppressing glucagon release, slowing gastric emptying, and reducing appetite through central nervous system effects. | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. |
| Typical Dosage | Saxenda (weight loss): Start 0.6mg daily, increase weekly by 0.6mg to maintenance dose of 3mg daily. Victoza (diabetes): 0.6mg to 1.8mg daily. | 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 daily at any time, independent of meals. Rotate injection sites. Can be used with oral diabetes medications. | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. |
| Side Effects | Nausea, vomiting, diarrhea, constipation, headache, decreased appetite. GI effects typically diminish over time with continued use. | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. |
