I take many nutritional supplements. I've tried other protein supplements, usually powder. When I started Advanced Amino, because my body is sensitive and quickly responsive, I KNEW, beyond a shadow of a doubt I had the BEST PRODUCT inside my body for helping build and maintain muscle strength. I could FEEL IT nourishing and affecting my muscles even before I started my workout. At 68, I have some audacious strength goals. If, by God's grace, I get to reach them, I will let you know, because Advanced Amino will have played a major role in reaching them. Thank you for making this outstanding, COMPLETE, quality product, which is MUCH EASIER to take than mixing a powder. Easier to take traveling, too.
