My dad starting taking SST (and loves it), and when I was in nursing school and he had me try one when I was trying to study for an exam, the focus was amazing. I've been a nurse for a couple of years now, and coworkers are always commenting on my ADD behavior. I figured I would try SST to see if it helped this behavior. To sum it up: SST works like Adderall for me. I am much more productive, I still have a ton of energy, and my coworkers have verbalized their appreciation of the focus that I now demonstrate when I take SST.
I am not taking SST for weight loss - but if it happens, great. I am regularly active and have a decent diet, so we will see.
Bottom Line: Yes, I would recommend this to a friend
