the best of its kind

Posted by Reviewer1556034 on Dec 26, 2007

I work out a lot, almost every day, and the combination of Arginine and choline from this product is making a big difference. I have more energy and metabolic boost - it's helping my body turn food into leaner muscle.

Great for releasing growth hormone when you work out and want to lose weight.

I love Durk Pearson & Sandy Shaw products. The fact that they are scientists and have made these products for their own use makes me confident of there effectiveness. I have been taking there suppliments for over 20 years.

Stimulates muscle growth and more

Posted by Reviewer3128906 on Nov 19, 2008

The key ingredient in this product is known for stimulating the production of human growth hormone which is radically reduced as we get older. The benefit of HGH is that it helps build muscle. It is useful when working out in a gym to build muscle but it is also useful in recovery from surgery. A pleasant side effect is the slight increase in libido men will get from use of this product.

Inner Power

Posted by Reviewer3153983 on Apr 24, 2009

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.

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.

This is an excellent product!!

Posted by Reviewer2810542 on Oct 18, 2010

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.

inner power

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.
