Overview

AMPK activator with exercise mimetic properties. Improves endurance and fat oxidation. Adenosine analog that directly activates AMPK kinase.

AICAR is studied as an "exercise mimetic": by directly activating AMPK kinase, it partially mimics the metabolic signaling induced by endurance training, with increased fatty acid oxidation and muscle glucose uptake. Preclinical models have shown improved aerobic capacity even in sedentary animals.

Although often grouped with research peptides, it is a small molecule (a nucleoside analog). It has no regulatory approval; abroad it is available as a research product and, in some countries, compounded off-label. WADA lists it as a substance prohibited in sport, in the group of hormonal and metabolic modulators, precisely because of its potential to improve performance without corresponding training. High doses are associated with hypoglycemia and a risk of lactic acidosis.

Small molecule — nucleoside analog (AICA ribonucleoside), not a peptide
