was about 4 hrs with about extra hr where the effects were slowly going away... it was kinda like 200 mg of phenylP, but different my mind just felt clearer, more focused, alert, kinda like a overall heightened sense of awareness. This is great for a long day at work, to help you study, get rid of brain fog, help with memory recall/retention, and you can also use to on days you are feeling lazy to help you get up and go!!
