Definitely worth the purchase.

I have used this product before and the new formula is equally good as the old formula.

I have total confidence in Durk and Sandy formulas. These two research scientists know how to put the ingredients together in a way that lets your body use them successfully. This formula helps me develop muscle and is equally good for your heart...with a nitric oxide release.
This is an excellent product!!

This arginine-rich formula has given me muscle-toning and fat burning results for years. I use it off and on, and can note the muscle toning effect overnight or within an hour or so. I use it before skiing or physical exertion and have much better stamina and muscle control. Also helps my vocal range when I sing barbershop. Whittles my midriff starting at waist and carves both up and down from there with continued use. I am not kidding. Try it.

I take this product in the morning on an empty stomach. It gives me energy to exercise and rebuilds muscle tissue. Love this company, too.

15 years and still no sore muscles from working out and can push a little harder during a workout.

I take Inner Power with WOW before working out every morning (and have for more than 20 years). WOW gives me energy and Inner Power increases the effects of the work out on circulation and muscle mass. I enjoy the taste and notice the performance improvement and the lack there of if I forget and skip a serving before a workout. This is the best product for those with a long term, consistent exercise program.
Excellent formulation, prefer no Ace-k

A formulation used and tested extensively. Putting Acesulfame-K seems to be an unnecessary unknown. I would prefer the product unsweetened, or just sweetened with Stevia. There is already an alternate formula which includes Acesulfame-K and Sucralose.
