Side-by-Side Comparison

AspectEpithalaminTesamorelin
MechanismSimilar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms.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 dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols.FDA-approved dose: 2mg administered subcutaneously once daily. Research protocols may use various dosing schedules.
AdministrationIntramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon.Subcutaneous injection into the abdomen. Rotate injection sites. Best administered at the same time daily, preferably in the evening.
Side EffectsGenerally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon.Common side effects include injection site reactions (erythema, pruritus), joint pain, peripheral edema, and muscle pain. May cause elevated blood glucose.
