AICAR vs GHRP-2

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.

Synthetic hexapeptide that stimulates pulsatile growth hormone release from the anterior pituitary by acting on the ghrelin receptor (GHSR-1a). Commonly stacked with GHRH analogs such as CJC-1295 or Sermorelin to amplify GH output synergistically.

GHRP-2 is a synthetic growth hormone secretagogue that triggers natural GH release from the pituitary gland. It is commonly used alongside GHRH analogs to support muscle growth, fat loss, and recovery. For educational purposes only — consult a qualified healthcare provider.
