Hi joegrane, i understand you may have seen a bunch of hair tests on that site? (cant remember which one again), my brother has been feeling fatigued of late and did a hair test and this is what came up, (its under "hair test bro" in the image section, i think theres only 4 images in there anyway lol), i understand the lead to be probably the biggest thing? dont know about the titanium.... they all say aluminium is a synergist for everything...theres a little bit of merc to which surpised me. anyway any input on hair test appreciated
