Does What it Needs to Do ----LOVE THE PRICE Love the higher mg which allows me to take less pills which I LOVE February 1, 2014
Great product After trying other brands, I came back to this one from Now Foods, and Swanson as the best price and fantastic delivery. December 10, 2012
Tablets break open Less than a month after buying these tablets they started breaking open. I contacted NOW foods and they said it was a "known" issue. The person I contacted said it was the humidity that does it and I explained I do not live in a humid part of the country. He then told me I stored them too close to a water source. Which I did not. I will not purchase from NOW foods any more. November 25, 2012
Amino power I bought this because it is supposed to help your body make HGH which is responsible for our youthful appearance, Not quite sure if its working but I will try it or 6 months and give another review. March 31, 2012
