Most pre work outs will tell you do not take within 5-6 hours of going to bed. I have tried most of them I find that jack3d is the best for me which I still currently use as I have someone that get it for me. Depending on what your looking to do you can use creatine aswell. When looming to buy a pre workout gaspari and USPS labs are the best they make them in small batches making them more potent than some like musclepharm where they are made in large batches and one may be really good and you may not feel anything in the bottle beside it.
