What is most telling about all of this is that there is no honest discussion. My only initial comment was that this blocks the same protein that ivermectin does. Multiple studies confirm this, its easy to search for them, and it has been the hypothesized mechanism by which ivermectin may show some efficacy.
I am not making any claims of any of these substances effectiveness in treating covid. I'm just pointing out that this substance claims to block the same human protein ivermectin does. We can all make of that what we will.
