i got my package in the mail today. luckily it was before my workout, so i popped 5 caps 45 minutes pre with a protein/carb shake. it was a shoulder day, and started to really kick in after my 2nd set of military press. using the weight i usually have trouble with for the first set of 10, and then need a spot for my next set, i got 4 full sets off. i had an absolutely amazing workout. i used slightly more weight on every exercise, plus i added a set to them all, so instead of doing 3 sets of each i did 4. i even added 3 sets of arnold press to the end of my workout which a normally don't do, and to top it all off, i finished the workout about 5 minutes quicker then i normally would. amazing product so far, i can't wait to try it on a leg day. the 5 caps felt right for me, so im going to stick to that. i have a very high tolerance to stims.
