A side-by-side research comparison of Epithalon and Spermidine across mechanism, dosing, half-life, benefits, side effects and research status.

Comparison table

AttributeEpithalonSpermidine
Full nameEpithalon (Epitalon / Epithalone)Spermidine (Polyamine)
CategoryAnti-AgingAnti-Aging
StatusResearch compoundDietary compound (research ongoing)
MechanismActivates telomerase reverse transcriptase (hTERT) expression for telomere maintenance. Also normalizes circadian rhythm via melatonin regulation and modulates antioxidant enzymes.Induces autophagy, partly by inhibiting acetyltransferase activity and mimicking caloric restriction signaling. This promotes clearance of damaged proteins and organelles, supporting cellular renewal, cardiovascular health, and cognition.
Molecular weight390.4 Da145.25 Da
Half-life3-4 hoursShort; rapidly absorbed and distributed
BioavailabilityHigh (SubQ)Oral absorption reported; also produced by gut bacteria
Typical dose5-10 mg1-10 mg per day
FrequencyDaily for 10-20 daysOnce daily
RouteSubcutaneous injectionOral
