I didn't get nauseous but had the flu like symptoms and terrible back pain, despite the taurine and potassium I took. Had a headache everyday untill I got off of it after two weeks. Felt in a 'fog' all of the time , hard time concentrating and basically felt like **** those couple weeks.
I couldn't deal with feeling like crap all the time as I work a physical, full time job and run two small businesses of my own. Even if I saw some gains ( which I didn't ) it wouldn't be worth feeling like **** 24/7.
I went back to T 1 Pro instead which I was really happy with and had no side effects at all.
