I've only been using T-rex for about a week, but I have to say I haven't felt anything. No increased heat feeling, no extra feeling of alertness, no sweating. I'm not on any low carb diet, do not smoke, and have not used any kind of ephedra products recently, only regular caffeine.
I started the first day with 1 cap in the morning, an hour before morning cardio. Didn't notice any difference from other days.
Next day I increased to two at same day, one in the morning and one before workout in the afternoon.
On the third day, 2 in the morning, 1 at lunch and 1 before workout.
4th day 2 three times a day.
I usually start at 5am with the first two (with a banana), and was kinda hoping it would wake me up a bit, but it didn't.
I have gotten a slight headache from time to time, but that's probably due to low bloodsugar (I use Glucorell with carb meals)
Also after I started using T-rex, my stomach has started messing with me. Maybe I'm immune, or having an allergic reaction or something similar, i don't know. But if anyone has some input it would be appreciated.
I'm 27 years old, 100kg, 6'2" and a bf at 12-14%
Thanx
