AICAR (5-aminoimidazole-4-carboxamide ribonucleotide)

AICAR (5-aminoimidazole-4-carboxamide ribonucleotide) is a compound that mimics a natural energy sensor in the body, called AMP. When AICAR enters cells, it activates a protein called AMPK, which helps regulate how cells use energy, especially during exercise or fasting. This activation can improve metabolism, increase endurance, and potentially support muscle recovery. Researchers are interested in AICAR for its potential to treat metabolic disorders, enhance athletic performance, and promote healthy aging, though its use is still under study and not widely approved for general medical or athletic purposes.
