Alpha-GPC Recommended Dose

I was wondering what the recommended dosage of Alpha-GPC should be. I know its 2 capsules 60-90 minutes before exercise but I was wondering if there were any negative effects from using it too much such as. I used for the gym, and I wanna use it for my basketball game which is 3 hours after I got back from the gym. Just curious, thanks.

I find that Alpha-GPC has a positive effect on me for the entire day when I take it in the morning, so I doubt that you’ll need a second daily dosage before basketball.

FWIW, I usually use 2 capsules at a time.
