I've been chatting with the Calcitriol/PCa researcher and he claims it requires megadoses of calcitiriol specifically that aren't available. Can you launder some of your dog's out?
I found out the local Walgreens has 50,000 IU tablets by prescription. But..the rsearcher says it can't be true calcitriol so it isn't applicable. my last e-mail to him, I asked if that means megadoses of D3 or the like might have any benefit/synergy. No word back yet. They, of course, are working on a wiz bang Calcitriol formulation. The comparison between Vit D and Metformin seems promising so..maybe....
