Side-by-Side Comparison

AspectLL-37 (Cathelicidin)SHLP2
MechanismDisrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects.Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways.
Typical DosageResearch protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections.Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established.
AdministrationSubcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols.Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties.
Side EffectsInjection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses.Limited data. Animal studies suggest good tolerability. May affect glucose metabolism.
