I have tried Ivermectin and some other things that are not on that list that I can't remember.
I do not know if Nitroscanate acts systemically... I didn't find any information on its use in humans but I saw that it has a very high safety margin so I might try it at my own risk, after researching a little more.
I have not tried DEC, I private messaged herne about DEC but I'm not sure if she will answer me because she is taking a break from the forums.
Can you tell me your DEC protocol?
How does doxycycline and bactrim fit in?
