Lahrok doesn't want suggestions, discussion, web links, etc. The message is quite clear: "Everyone focuses on everything except my original question: "How can I get Bithionol?" And the original question has been left unanswered for 3+ months now even though it is so simple."
The simple answer appears to be - you can't.
Perhaps Lahrok could start a research company and use that company's credentials to order the product? :)
