Oh! It works alright.
I have an illness where I have to take some very sedating medications. Half of my awake time is spent feeling very doped up. This medication cuts through the brain fog and allows me to be productive. I would have given it five stars, but I wish it came in a tablet form that could be cut. A word of caution. Do eat before as directed, and monitor your blood pressure on your first use. Like most stimulants, it may become less effective over time. In this case stop using for a few days.

These work.
I’m 78 years young. I felt like I wanted to go to sleep while I was golfing or working in my garage. I needed some extra energy. I tried these and they work. The need to nap feeling is gone.

GREAT PRODUCT
This product is all that it advertises to be. I have been taking it under a month and hope I never have to be without it. I have been doing more housework and yardwork in the last two weeks than I have been able to do in a long time. I dig into my chores instead of putting them aside for later. Thank you Energysyl. I have recommended your products to others and will continue to do so.
