Any expat chemists that can compare ********** dosages?

Medical grade ********** is not available in the PH and very likely will NOT be allowed in spite of its possible efficacy against covid. That leaves Filipinos no choice but to use the readily available veterinary grade if that is their only option. Putting aside the so-called "safety" standards in regards to comparing the two grades, does anyone know how to compare dosage between the vet' and medical grades? For example, how does 12mg of medical grade ********** compare to the vet grade 2mg (0.3%)? The reality is that people are going to self-administer this medication considering the proven safety profile after 40 years of use, so they might as well know how to compare dosages so that they do not abuse the safety profile. I am in no way recommending or advising anyone on it use.
