Just wanted to let you all know that Mass Tabs are bunk. 2 weeks ago I was on a "cycle" of Mass Tabs and ending my 3rd week...I went to the doctor to get some blood work done and as of today I have been told my Test levels are low. I have high thyroxine levels and everything else is "normal." We did another blood test today and I will get those results back next week. Just doesn't seem right not to pass this on. BTW, I've never done a "real" cycle so my test levels have no reason to be out of whack other than using the MassTabs
