LL-37 (Cathelicidin) vs Gonadorelin

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.

Gonadorelin

Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.

Side-by-Side Comparison

AspectLL-37 (Cathelicidin)Gonadorelin
MechanismDisrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects.Binds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production.
Typical DosageResearch protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections.Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies.
AdministrationSubcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols.Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy.
Side EffectsInjection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses.Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated.
