If you’re looking for a vasodilator you can try gingko biloba, although I have no idea if that boosts the effects of Alpha GPC.
For neuro supplements I take gingko biloba (120mg) in the morning with breakfast (after training) with Alpha GPC (300mg), Phosphatidylserine (300mg), and acetyl-l-carnitine (1g). I also take Alpha GPC (300mg), Phosphatidylserine (300mg), and acetyl-l-carnitine (1g) with dinner. Before I go to bed I have acetyl-l-carnitine (1g) with a large spoonful of nordic naturals ulimate omega xtra and a proteirn shake.
As far as noticeable effects, I can’t say for sure what Alpha GPC has had, I’ve tried going off and on and can’t really feel a noticeable difference but I remain optimistic that there is something that is either subtle or gradual about it. However I do notice a big difference at night with acetyl-l-carnitine especially mixed with fish oil (I’ve tried removing one, the other, and both). When I take those two with my protein shake at night I tend to have really vivid dreams and wake up very well rested. Whether or not there is a neurological benefit, the improved sleep quality is enough for me to continue taking those in combination.
Since we’re on the topic of vasodilators, I’m curious if your body builds a tolerance to ginkgo or vinpocetine and if they should be cycled
