Carnosine vs N-Acetyl Epithalon Amidate

Carnosine vs N-Acetyl Epithalon Amidate — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Carnosine
Anti-aging & Longevity

L-Carnosine (beta-alanyl-L-histidine) is an endogenous dipeptide found in high concentrations in skeletal muscle, brain, and heart tissue. First discovered by Russian biochemist Vladimir Gulevich in 1900, carnosine has been investigated for over a century for its multi-modal biol...

N-Acetyl Epithalon Amidate
Anti-aging & Longevity

N-Acetyl Epithalon Amidate is a chemically modified form of Epithalon (Ala-Glu-Pro-Gly) in which the free amino terminus is capped with an acetyl group and the C-terminal carboxyl is converted to an amide. These two modifications collectively prevent degradation by aminopeptidase...
