Admittedly, this one is hard to accurately talk about performance
I’m taking it for close to two years every day and my blood test which are very comprehensive turn out really well. I think in part it’s due to this product, but of course that’s impossible to isolate because it’s not the only supplement I take. At this point, I keep taking this because, my health is excellent and better than many people my age or younger, so I’m not going to mess with the formula that works. I would have to be a chemist with a biology emphasis to really give factual response on the performance of it which I’m not. I am, however very interested in maintaining my health and doing a decent job of it thank God. I have no problem recommending this , as it looks like all the ingredients I have read about that are beneficial are contained within it, and the price point is very reasonable, not cheap but reasonable

Large Pill
Shipped fast and no damage. Pills are very large so I cut in half and take half at a time. I can’t really tell any benefits from taking them so I don’t think I’ll purchase again.

Convenient Daily Amino Acid Supplement
These amino acid tablets are easy to add to a daily fitness routine, and the 120-count bottle provides a generous supply. I like that the formula combines essential amino acids in one non-GMO supplement. The tablets are convenient for active men and women looking to complement their nutrition and workout recovery. It is important to follow the label and remember that supplements work best alongside adequate protein, hydration, and a balanced diet.
