Side-by-Side Comparison

AspectLL-37 (Cathelicidin)Ipamorelin
MechanismDisrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects.Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones.
Typical DosageResearch protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections.Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.
AdministrationSubcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols.Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.
Side EffectsInjection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses.Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.
