L-Arginine 1000 mg 240 Caps - Supports High Potency Nitric Oxide Levels Blood Flow Improve Energy Endurance for Men and Women

I have fibromyalgia and always looking for something to help my muscles function better. Wow... I noticed my large muscle groups (arms and thighs) seem to stretch better and "breathe." The effect lasted several hours on one dose, but I don't take more than one dose per 24 hrs. So, I guess you could say it's good quality since it "worked."To note: I researched and made sure it would not interfere with other medications before I got it. They say if you are on heart meds, blood thinners or high blood pressure meds, you should not take it, or talk with your doctor about adjusting your med doses to try it.

These capsoles at easy to swallow. They were recommended by my Orthopedics doctor, after my knee replacement to elevate the numbness around my scar. I am on my third bottle and the numb area is shrinking. I will recommend this product to my friends.

I've used this for a month and feel great. I have more energy during workouts and get really good pumps.Thank you

I cannot feel any noticeable difference.

Excelente producto me ha mejorado mucho lo recomiendo
