This stuff will keep you up. Not just your swantz but trying to sleep for me was impossible. So if your doing a all nighter great. Since it lasts in me aprox 10 hrs, last time I took it at 2:00pm. The girl was happy and I was asleep by 1:00am. Just factor that in. Just like the other reviewers I dont know whats in it but its the real deal, you wont be disappointed. |
