I am a 63 year old, that has been taking Advanced Aminos for years. I’ve kept my muscle mass and continue to work out 3 to 4 times a week. I attended and successfully passed rookie school at the TN Fire Academy in December 2024. I performed every task the 20-year olds did, including climbing a 35’ ladder with 70 lbs of gear on, and hauling out a 150 lb “victim” from a search and rescue drill. The 20-year olds were cheering on “Papaw” from all over the drill field as I completed the drills. I take 5 pills as a breakfast replacement, which helps with weight management. I’m a big believer in the product and will continue to use it.
