AspectLL-37 (Cathelicidin)Tesamorelin
MechanismDisrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects.Stimulates the pituitary gland to produce and release growth hormone by binding to GHRH receptors. Increases IGF-1 levels which promotes lipolysis and reduces visceral adipose tissue.
Typical DosageResearch protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections.FDA-approved dose: 2mg administered subcutaneously once daily. Research protocols may use various dosing schedules.
AdministrationSubcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols.Subcutaneous injection into the abdomen. Rotate injection sites. Best administered at the same time daily, preferably in the evening.
Side EffectsInjection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses.Common side effects include injection site reactions (erythema, pruritus), joint pain, peripheral edema, and muscle pain. May cause elevated blood glucose.
