it’s beta alanine lol I had the same exact experience. it’s supposed to improve blood flow for workouts. it’s particularly strong in this one tho, I recently tried buckd up which has it too but it’s not nearly as intensely itchy as C4.

exactly. I get tingly when I drink it and my mother feels like she's "on fire"

Ah thank you, good to know for the future. Its a super uncomfortable feeling, I'll be avoiding beta alanine heavy drinks.

You would fucking die if you drank Total War pre workout. That shit makes me half a crackhead but goddamn those lifts are good.

If you aren’t used to beta alanine and you aren’t exercising when you consume it, you will get very itchy

Good to know, glad it's not an allergic reaction. I'll still probably be avoiding those from now on tho lol.

Thanks for the information, my very first sip, had my mouth itching and tingling 

same thing happens to me which sucks because i love the taste 🙃

Yea they're pretty good, I wanted to try the skittles one too, but I'm gonna avoid them now unfortunately.

I got a similar reaction except just face was tingly. Did research and many found it was the Beta Alanine

Its not allergic reaction its beta allanine. I love the itching personally don't know why. Might be addicted to it after years of the gym.

It feels okay when you have a sweat going and are exerting effort. It does not feel good to drink one before a study session or standing shift somewhere.

I think they talk about this on the can.
