I started taking Advanced Amino about 30 days ago, I admit I was skeptical. I have been fooled by fake products that were a waste of money. I am 75 years of age and live on social security, I can’t afford to waste money. Thank God this product is well worth the price. I have energy all day like I did not have until I started using Advanced Amino and I am more alert. I am a very active person, I work out 3 to 4 days a week, I ride my Harley. I visit with friends and family and my energy level great. Thank you for this product. I will keep using Advanced Amino.
