I'm a typical hacker News person. Been suffering from long covid for over a year. Tried horse paste and I got relief. When I stopped taking it the long covid symptoms returned. So taking it regularly now and it helps. I'm a few weeks in though so take this with a large pile of salt.
Oh and the active ingredient is identical to the human pills. The other ingredients are all safe and common.
The arguments about getting the dosage wrong are valid. For most anyone here doing a simple calculation and being confident enough in it to bet your life on it is generally fine, but I can see people in the general population messing up simple arithmetic.
Disclaimer: if you take medicine based on a hacker News post you're a moron.
