I want to buy the GSH that can be inhaled for my 3 year old son who lost 2 pounds and grew 2 inches. This dropped him from the 75th to the 27th precentile since his last clinic visit. I know the Thera Naturals has a GSH-Curc caps and they have GSH caps, so which ones can be inhaled? Is there another brand out there? What is a safe dose to start with a 3 year old who weighs 29 pounds? Thanks in advance for any advice or help.
