Alpha-GPC

Choline source taken before workouts or hard cognitive work

300-600mg of a choline compound for acetylcholine support, before training or a demanding block of focused work. Reported effects are subtle: sharper concentration, slightly better power output. There has been some debate about high chronic doses and cardiovascular markers, so most users treat it as occasional rather than daily.
