Ephedrine/Speed like effect when combining NYC and L-carnitine?

[Delinquent]

Has anyone felt like they were on a lot ephedrine when combining these two? I am literally bouncing off the walls when I take 2 NYC and 500mg of L-carnitine together. If I only take the NYC, I'm normally just really warm but not speedy. The last time I took NYC, I didn't have any of these so it leads me to believe that the L-carnitine has something to do with it.

i was just wondering, does NYC elevate your heart rate like ECA?
i would like to take a thermo to help with cutting but don't tolerate ephedra well, and i'm in the high normal BP range, so i'm trying to get some feedback on the effects NYC has on the heart
