I finally found a doctor that would send for this test. The normal range for GSH is 544-1228 uM (I'm not familiar with uM). My level was at 588. This test was taken a week into me going back onto 1000 mg per day. I am still working up to my 3500mg per day dose.

I will be having the blood test done again in a few months to collect data for my personal curiosity.

I am hoping to regain 10% FEV1 by October 2015 from GSH usage. I was able to do it in the past. Fingers crossed!
