So you had blood work, what was the hematocrit?

That is an estimate, not the real value, and its multiply by 3. Post your BW.

HCT is the hematocrit and is at 43%, so pretty low.

It is true that B12 is required to the erythrocyte (RBC) formation, iron also enters this equation, and steroids will elevate erythropoiesis (sorry for the spelling, I think lol), but yours is still quite normal.

B12 is water soluble vitamin, so your body will easily excret excess, 5000mcg orally I would not say its low dose but its not mega dose. I have injectable B12 of 20mgs, ussually only use a quarter or a fifth of it per week, but it is injectable, in orals you have to account absortion which can be like 50% or less.
So maybe reduced to 2-3 times per week, and you should be fine.

Same here.

Drastic appetite increase will not happen on b12 whatever dose.
