01Mechanism of Action
Parameter
Epitalon
Retatrutide
Primary target
Telomerase activity (proposed); pineal melatonin axis modulationKhavinson 2003
GLP-1R + GIPR + Glucagon receptor (triple agonism)Jastreboff 2023
Pathway
Activation of telomerase reverse transcriptase (hTERT) in somatic cells; pineal-axis modulation supports endogenous melatoninKhavinson 2003
Triple-receptor activation → ↑insulin (GLP-1+GIP), ↓gastric emptying, ↑lipid handling, ↑energy expenditure (glucagon component)Jastreboff 2023
Downstream effect
Telomere elongation, improved sleep architecture, reported lifespan extension in aged miceKhavinson 2003
Maximal weight loss across class. Glucagon component drives lipolysis and energy expenditure beyond GLP-1+GIP aloneJastreboff 2023
