Good supplement for working out
I have been taking this for about four months now and really notice a difference with my post-workout recovery. Tablet is not too big which makes it easier to take every day :)

Inclusion Body Myositis
I take this for myositis--there is no treatment for the kind of myositis I have--my disease progression has been slow--so maybe it is helping. There is no scientific way to evaluate whether it is this supplement or a host of others that I take.

Excellent Product
I take 1 pill 2x a day. As a vasodialator it has allowed me to keep my BP out of the danger zone [below 140]. I am a 65 year old male about 30 Lb overweight and do only moderate exercise every day. This has helped me tremendously!

I never received it
According to the tracking number 74899994595147029855 this item was delivered to my mail box at Tue 3/28/2017 11:20 am but B maybe the mailman mistakenly left it in another mailbox because I never received it. This is the first time happen with a GNC shipping. I don't know what to do. Seems to me that i lost my money and I'm afraid to put another GNC on line order. Maybe I will buy a similar product from another brand. Sorry

Best Supplementary for hearts
My parents have taken this supplementary for more than a year. They are very satisfied and their hearts are getting stronger.
