Yes Archie is still using it every day, orally and inhaled. His health has been amazing, breathing tests 107%, never been in hospital...has huge amounts of energy and is doing really well in all the sports he does...which is quite a few. I strongly believe GSH has made a huge difference to his health. I look forward to hearing the results from the clinical trials to show how good this antioxidant is for our CFers. Fingers crossed we breeze through winter again this year
