We've never claimed ULtima to be a 1-workout wonder like many pump 'n stim mixes out there. And if you are accustomed to taking stimulants pre-workout, your body is going to need a period of adjustment to get back to normal.
Ultima is superior, however for intense min-muscle connection and focus. The endurance is unreal and the strength gains are too after about week 2. It is really important to remember that the results get better as user duration increases and really hits the sweet spot in week 2-3. We have made many believers out of this product in week three who were ready to quit after day 2 because they did not get that "amped out of my mind with amphetamines" feeling.
Once my Ultima arrives I'm going to start a log and document the experience; really looking forward to this!
