Pain*
So... I bought these pills at GNC. A few hours later I took three of them (recommended dosage for someone new to taking them), but I took them without water. Big mistake.
I ended up feeling the worse burning sensation in my chest area. (lower esophagus). It felt like I ate a lot of food at once and it got stuck in my throat. I almost had to throw up, but couldn't.
The extreme pain lasted for about 2 hours and then the pain subsided slightly, but still wouldn't go away. That was 5 days ago. After two days passed where I could barely even take down water, I finally decided to go in to the doctor for it.
Here to find out, I tore the lining of my lower esophagus. And because L-arginine increases acid in the body, it probably made it worse. It hurts extremely bad when I eat. On a scale from 1 to 10, (10 being an amputation), it's about a 6-7. I have lost 7 pounds in 5 days because of this.
I'd advise anybody taking pills to make sure that they drink an adequate amount of water with them.
But on other news, I believe they work. I've used NO2 products before by Muscletech and they definitely helped my stamina and pump in the gym. You can get definite gains from these NO2 products if used correctly.
