I used Alpha-GPC some time ago and didn’t notice much of an effect. However, I like to go back and try things again after a good break just to make sure I didn’t “miss” something earlier.
Now that Alpha-GPC has been around for quite some time, do people prefer to use it:
Pre-workout for the increased focus and neural drive (performance), or
Pre-bed for increased sleep quality and recovery
Let me know your thoughts and experience,
