Side-by-Side Comparison

AspectEpigenTesamorelin
MechanismBinds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes.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 DosageTopical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.FDA-approved dose: 2mg administered subcutaneously once daily. Research protocols may use various dosing schedules.
AdministrationPrimarily topical application for skincare. Research may use other routes for systemic effects.Subcutaneous injection into the abdomen. Rotate injection sites. Best administered at the same time daily, preferably in the evening.
Side EffectsTopical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.Common side effects include injection site reactions (erythema, pruritus), joint pain, peripheral edema, and muscle pain. May cause elevated blood glucose.
