I have tried three ibe product and I will say that I am impressed. x-force is probably the best energy product that I have tried. it provides clean, smooth, long lasting energy. It also provides great focus and mood. It does not overstimulate or make it feel like your heart is going to explode. I feel that it is superior to other stims like stim x, amp, camph intense (another great stim) and E/C. the second product I tried was neuro-balance. This is great for sleep. I can sleep a solid 10 hours on this and it gives me very realistic intense dreams. it also makes me relaxed so falling asleep is very easy. I have tried a lot of different things for sleep and this is one of the best. i take 1 tsp before sleep on nights where I need some good sleep. the only bad thing about it is price. I feel it it too expensive for everyday use. the last product I tried was matrix. the effect were similar to x-force but it felt a little weaker. this was probably due to the fact that I was burned out from too much work and not enough sleep. the taste wasn't bad but it did have a chemically aftertaste. i feel that it easily beats any of the energy drinks currently on the market.
