What Are the Bad Possible Side Effects of an Intense Pre-Workout Supplement Like Jack3d?

Question by Evan F: What are the bad possible side effects of an intense pre-workout supplement like jack3d?
It has ingredients like geranium (more potent then ephedrine and just short of amphetamine) and Schizandrol A which “outperforms amphetamines cognitively”. Basically this stuff is like speed and I feel like that would have some bad side effects. I have used it for 2 months and gained 10lbs. Its so ridiculously amazing to work out with that I feel it is unhealthy.
To add, I am a 18 yr old NCAA track sprinter. I am looking for high muscle and low fat. I was 178lbs in my prime after coming off of this stuff. My normal weight is about 168
