Isn't it in stock? - http://www.m5research.com/products.htm
They don't sell it from the PE website? The Thyro Activator brand is cheaper, and there is free shipping from PE.com.
I believe PE owns M5. Talk to HUGE about it and maybe he'll hook you up with free shipping.
We were told by the FDA ( a friendly visit) that we could no longer sell tiratricol as a *dietary supplement*. So we do not sell it as a dietary supplement- M5 sells it (but not as a dietary supplement of course)
