I think you're right. Anyone who would post an altered lab report must have an agenda of some sort. If no one can post a lab report of Gallstones or liverstones, maybe people who do these flushes(which appear to be quite a few) aren't passing either gall or liver stones afterall. I'm still not sure what a liverstone is anyways. If these "flushes" aren't flushing what people expect, it might call into question the whole purpose of some of these websites that tout flushes, and other things.
Do you know anyone who's tried a flush and taken it to a lab?
