Yeah coffee.
Why not try running or high rep warmups so you wont have the tingles?
Since you want to stay away from stims, I’d suggest VasoMax. It does not contain beta alanine (which is what causes the tingles you don’t like) and contains glycerol power and potassium nitrate (along with other goodies) to help you achieve a killer pump. Tastes pretty good also. I haven’t had the new flavor yet though.
I was thinking about coffee but I've read that caffeic acid activates AMPK so I tend to shy away from using it as a PWO.
