Trap and a few other long-term Lugol's users have reported it being more difficult (oxidizing) to take a larger dose for too long and that switching to magnescent enabled Trap, anyway, to take much larger doses. I've wanted to go higher but wasn't sure. I'd read that a lot of people were able to do large doses 300+ for a little bit but then had to come back down. So far as I know, you're the only person I've read about taking 5% at that level for that sustained a period. And you haven't been seriously dosing with anti-oxidants? Are you a super hero or something?
