Alright I have had my share of pre-workout supps and I have only ran across 2 that have given me some bad side effects. One of them happened to me today. I took a new pre-workout today and 10 min later my entire face, parts of my arms, and my knees turned sunburn red and felt like a really bad sunburn. It was kinda painful at times, but it passed within an hour. What do yall think is going on? Others I take do not do this to me, only two of the products have done it out of probably 6 I have tried.
