Disclaimer: I am a person who notices very small changes. I am very thin. Within the first day of taking Advanced Amino (I only took 3 tablets the first time), I looked in the mirror before bedtime and my arms looked bigger - no joke! I squeezed them and they felt firmer. A few hours after taking Advanced Amino, I remember feeling satisfied. My body had been starving for so long for this nutrition that it had put it to immediate use!
Very satisfied! However, the shape and size of the tablets can make it hard for someone like me to swallow them. (I have trouble swallowing things "whole", but I'm getting better at it.) The tablets are average-sized though.
PS: Don't mash them into a powder and drink in water! Amino Acids are, well, acid. They will burn your throat.
PPS: They are best taken an hour or so before other protein sources - for the best results! Enjoy!
