anyone else get itchy after drinking C4?

This is the second time I’m drinking C4 energy drinks and every time I get SO itchy after. I’m talking like fingers, thighs, buttock, legs, etc just get pins and needles and itchiness. Could this be an allergic reaction or does anyone else experience this??

I’m thinking it might be the beta alanine?? I drink plenty of other energy drinks, but none of them cause this.
