Started taking Advanced Amino July 27/21. There were 153 tablets, and it was recommended that I take 5 per day, so I started with the uneven number of 3, with 5 thereafter until 4 days ago, August 12/21, at which time I had taken another 2 in the afternoon because I was feeling a little washed out from the project I was involved with. It was fairly strenuous, and I had just watched your Video with Frank and David the evening before. As a result from watching the video I changed 2 things. I had initially started taking my allotment of 5 tablets each morning with my Breakfast , but changed to taking them prior to Breakfast, and also, because my daily activity was fairly demanding, I decided to take an additional 2 in the afternoon. Believe me, what a difference. I mean, what I had been experiencing was already quite remarkable, but, the additional 2 in the afternoon was really spectacular. I've had a long day today also, so this afternoon, I took an extra 2 tablets, which allowed me to put in a remarkable day. I will continue to only add an additional 2 in afternoons, when my day is extra demanding. Seems to be an exceptional product. I'm keeping a periodic log of my usage.
