A choline donor used mainly as a pre-workout or cognitive supplement, commonly taken in single doses around 300–600 mg for performance and sometimes split into multiple doses totaling up to about 1,200 mg/day in study settings. It’s used to support acetylcholine production, which may help power output, focus, and other aspects of mental and physical performance.

I will often take 300 milligrams of alpha-GPC prior to workouts or prior to cognitive work bouts. I tend to take it alongside caffeine and phenylethylamine.
