I've been googling and I keep getting different answers. So what's the deal?
I have a feeling caffeine has been inhibiting my vascularity. Normally I'm quite vascular and add in some pump ingredients and it really shines, but whenever I take a pre with caffeine I think it reduces it some what. Now I'm very stim sensitive because I don't take caffeine at all (no coffee etc), so caffeine is new to me per say.
I read on wiki that caffeine has a pressor effect (vasoconstriction) on people who are not used to it

Is caffeine a vasodilator or vasoconstricter?

It is a constrictor...what is your concern? Want more vascularity?
IMO if you are not abusing it, it will not have much effect on vascularity per say. I can take 300mg of straight caffeine and still veiny as hell.Type 1 Diabetic - Since age 15

I'm in with Steven on this one, usually vascularity can be a result of your diet, have you changed that at all. Have you been eating lower carbs or changed your fats around? This can all have an effect as well, or maybe your holding. Little subcutaneous water from creatine, just all possible scenarios.

Its often a peripheral vasodilator along with its central vasoconstriction
