I love this pre-workout! I have tried many "natural" ones. This one has a great taste and gives me an energy boost that I am looking for without any jitters. It only has 40mg of caffeine per serving so you aren't getting too much caffeine either which is good. The only thing to be aware of is it may giving you a slight burning sensation if you drink it quickly. I usually feel it in my face. I'm used to it now and kind of like it!!
I enjoy this pre-workout. I worked a 12 hour shift in construction and drank one serving before work and I had energy all day with no crash. I also didn't feel a huge "pump" like other pre-workouts but that is why I bought this one.
