AICAR vs Humanin

AICAR vs Humanin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

AICAR
Mitochondrial & Longevity

AICAR (Acadesine) is a cell-permeable adenosine analog that is phosphorylated intracellularly to ZMP - a structural mimic of AMP that directly activates AMP-activated protein kinase (AMPK). AMPK is the master metabolic switch triggered by exercise, fasting, and caloric restrictio...

Humanin
Mitochondrial & Longevity

Humanin is a 21-amino acid mitochondrial-derived peptide (MDP) encoded within the 16S ribosomal RNA gene (MT-RNR2) of the mitochondrial genome - the same mitochondrial gene region that encodes MOTS-c. Discovered in 2001 from a cDNA library screening against Alzheimer's-linked neu...
