I just did a search on Amazon for it and doesn't even show up in a search now brings up such things as guitars when I typed in Ivermectin. Was clearly there earlier this week. Good luck finding it looks like either that all sold out or they got the word to pull it. If they sold out I would think it wold show up out of stock since I run into that message a lot on other items.
We in Indonesia can buy it easily on line. I bought a bottle last week of 100 caps of 5mg each for Rp110 000 (USD8.00). I am not entirely sure, however, that it is the real thing!
