Well for an xmas present, my buddy bought me a sh!t load of supps, one of them being Jacked. Monday night decided to give it a try, I've read some pretty potent reviews on it so I started with 1 scoop (I work out at night and hate being all stimmed out when I'm trying to fall asleep). I definitely noticed it after about 20 minutes. I didn't get the cracked out feeling I get on NO Xplode, just really focused and intense. Had a great Chest/Bicep workout, haven't been that pumped for a long time. Came home and had no trouble falling asleep. Last night (Tuesday) I decided to try 2 scoops for leg day. WOW. Haven't had that muched focus and energy in the gym for a while, again, didn't get cracked out. I have to say I'm very impressed with Jacked. I'll bump it to 3 scoops tomorrow and see ow that goes. Good job USP Labs! ~~freq-out~~
