He was heavily involved in our FDA phase 3 Euphrates Trial and is/was involved on the medical advisory board of CTSO. Given they announced the XL product in August of 2016 just 60 days after the Euphrates ended, it may be that endotoxin is indeed important. I can't see the medical advisory board suggesting the XL unless endotoxin is important. I don't think they've used it on a human, but CTSO can shadow dan$e with the XL for quite some time. Kellum has also served on the AEMD, or Aethlon advisory board. You do wonder why he was given a front seat view to everything "Euphrates". He is also rather tight with Claudio Ronco, the doc that plays with our all our toys but NEVER EVER mentions Spectral................................................................................................ No offence David....you're a bit of a scumbag, I suppose that is why you've mentioned the XL 4 door sedan, the friendly professor also brought this to the attention of our trusted leader as a "lost leader".....................................................................................................................................................
