I am trying to get into the navy and i was 1 body fat % over the maximum so i didnt get in....well i have 15 days till i go back and i recently went to the GNC store at the local mall and talk to the guy that worked there i told him how much wieght i needed to lose and how much time i had....he told me NITROTECH - protien food supplement was good and Hydroxycut was a good combo i am supposed to take the 3 hydroxycut pills 2X a day and the nitrotech 3x a day. my question is: Should i still eat or take that nitrotech instead of my meals..i have been doing this for a day now and working out twice a day doing cardio and lifting light wieghts i feel shakey...and very anxious should i stop taking it or what?
