It binds to IGF-1 receptors on muscle cells, triggering a cascade of anabolic processes: increased protein synthesis, enhanced nutrient uptake, and even the creation of new muscle cells (hyperplasia) : something most compounds can't do (Yakar et al., 2002)
Others try them if oral supplements do not seem to help
Choline, for example, is involved in lipid transport and metabolism (a vital part of energy storage), cell membrane signaling, and nervous system function
