What does NO mean?

My son has been on oral GSH since January and inhaled since August.

His main issue has been digestive and weight gain. Are any of ou familiar with Trenenen? It's suppose to help with absorption. I bought a one month supply. His weight was great at his last clinic but it could be because his new favorite food is Lays potato chips and we were able to do more feedings with his g-tube.

I'm very interested in adding Arginine. Any ideas on dosage for a 6 year old who weighs 44 pounds?

Thanks so much!
