I remember I had some kind of testing frm two different people (same method) in two different health food shops...I think it was a pengulim or something (I wouldn't do that these days).

Both told me completely different things. One said "you're ok with echinacea" the other said "you are not ok with echinacea"......so in the end you wonder if you should go around testing THEM to find out which one is accurate...

I"ve been tested on the same machine (bio com) by different people telling me different answers....i've been tested on different machines all saying different things. It got very confusing for me to say the least.

In the end, I got sick and tired of it (literally).
