Yellow Jacket + Training = ?

[Advaik]

Before I began my training today I took 2 yellow jackets, I found that I could run twice as much and lift twice as long (with my current wieght). I use to take ripped fuel before working out as it gave me a boost of energy but these yellow jackets seem to be 10x better. Are there any dangerous side affects of doing this? Perhaps from the caffiene, or lifting too much? Thanks

just hope you dont have to run alot, they leave you winded, at least when you stop taking them you are always out of breath when you run
