Not a professional but this is my story and I'm still here.
Found in old emails a registration to BHT group 19 Aug 2009, so that makes 8 year of 750mg per day and no ill effects.
The reason for all my "cures" is I was diagnosed with HepC-1A [the worst] I think in 1997/8.
I got hep probably in the mid 1980's and will turn 63 in a couple of days. Yes I have an end of life plan in place if needed.
I use MMS since 2012 [email history] and member #635.
Also Monolaurin pellets from Inspired Nutrition. 1 scoop AM and PM since before 2013 [? dumped a lot of old mails]. And many other special formulas and curcumin, dandelion, colloidal silver, Rife frequency unit, with liver detox and restoration formulas.
I also check on EarthClinic forum. He is a natural healer in the Philippines, which put me on a lot of the possible cures.
Last check up Jun 2017 my liver numbers had gone down from right at 100, marker of your going over the cliff, down to low 70's for both AST and ALT. Doc says he as seen 1000 but they were on life support as critical care, so it is individual based that some point usually in 400/500 the liver really goes bad and sclerosis and cancer can them move in.
Be well.
