I have been taking the Advanced Amino tablets for a little over a month now. I will be 60 this year and am in the gym for strength training 6 days a week. I have taken thousands of dollars of supplements over the years, from protein powders, testosterone boosters, BCAAs and you name it. As I am getting up there in years, I have found that injuries are slower to heal, energy to workout fades faster and constantly pushing my body to lift heavier has become more of an issue. What i have noticed so far with Advanced Amino is i began sleeping better within the first week. Since then I have noticed more energy during workouts, more power in pushing heavier weight and a better pump. I have been taking 7 tablets a day. Today I received my second order of Advanced Amino powder and intend on taking two servings a day instead of one, to maximize the positive affects. My employer (also a 60+ gym rat) took my advice and started on Advanced Amino about 2 weeks ago and says that he too is already noticing the results. Advanced Amino is a better supplement than any I have used before!
