Just spoke with someone about it. It blocks/reduces the white cells that make up your immune system by 70-80%. Effects production in lymph nodes. Also has heart, lung? and other neg. possible receptor effects(I forget). It was a long phonecall and was 1st thing we covered so the above info isn't spot on but it's close. Sounds like something I'd take at say 1/4 dose along with Ty if possible. If I could lower my white count by say 25%, I'd try that. Am I totally off saying it sounds like a chemo drug?
