AICAR vs Follistatin 344

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.

Binds and neutralizes myostatin (GDF-8) and activin; removes the natural brake on muscle growth allowing supraphysiological hypertrophy

A myostatin inhibitor that removes the natural limit on muscle growth. Produces dramatic increases in muscle mass and strength by blocking TGF-β family proteins.
