Review on 💪 L-Arginine 1000 mg 240 Caps - Enhances Nitric Oxide Production for Optimal Blood Flow, Energy, and Endurance in Men and Women by Kelly Burton

I have fibromyalgia and am always looking for something to help my muscles work better. Wow. I've found that my large muscle groups (arms and thighs) stretch and "breathe" better. The effects lasted several hours from one dose, but I don't take more than one dose a day. So you could say it's good quality because it "works". Note: I researched and made sure it doesn't interfere with other medications before receiving it. They say that if you're taking heart medication, blood thinners, or medication for high blood pressure, you shouldn't take them or talk to your doctor about adjusting the dose of your medication to try them.
