LL-37 (Cathelicidin) vs DSIP
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 →DSIP
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
Full details →Side-by-Side Comparison
| Aspect | LL-37 (Cathelicidin) | DSIP |
|---|---|---|
| Mechanism | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. |
| Typical Dosage | Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. |
| Administration | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. |
| Side Effects | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. | May cause grogginess upon waking, vivid dreams, or temporary headaches. |
