I am happy and thrilled with the product Advanced Amino . I am on my second month I’ve taken Advanced Amino powder every morning before my coffee and I have seen an increase in muscle mass in my arms, my calves ,and Glutes. I’m 78 years old and never thought I could ever regain my muscle as when I was in my 40s I am now able to exercise daily ,walk up and down my steps , without tiring out .I will continue taking this it’s an awesome product . Thank you Advanced Amino‘s !
