XRX
I have used XRX in the past. I only used it pre-workout. It was good for a pre-workout boost. Actually, the first couple weeks, it got me pretty jacked! How much are you using it?
I was going through an old gym bag the other day and ran across an old XRX bottle with a little left in it. I used it pre-workout and the shit almost killed me. I thought I was going to die... Eyes watered up, nose burned like shit and when a little dripped into my throat, it burned my throat and I thought I was going to puke from the nasty ass taste. Suggestion: don't use old XRX. There must be a pretty short life on it.
