I am by no means a Lugols expert... but I got myself the 7% and put 2 full droppers plus a half dropper in a coffee mug filled 3/4 of the way with orange or apple juice and I barely taste it... infact, I don't taste it at all.. I can slightly smell it more than anything and it tastes nothing like metal at all.
This guy got a bum batch... had to have been.
I just got a recipe to make my own so I know whats in it and how its handled.
