AICAR vs Hexarelin

Converted intracellularly to ZMP, a potent AMPK activator. AMPK activation increases fatty acid oxidation, glucose uptake, and mitochondrial biogenesis — the same metabolic pathways activated by sustained aerobic exercise.

A cell-permeable nucleoside analog that activates AMPK, mimicking cellular exercise signals. Studied for endurance enhancement and metabolic disease research. Not a true peptide — a synthetic nucleoside frequently sold by peptide vendors.

Potent synthetic GHRP; strongest GH secretagogue in its class; also activates CD36 scavenger receptor for cardioprotective effects

The most potent synthetic GHRP, stimulating significant GH release. Also has direct cardioprotective properties independent of GH.
