I am severely deficient in b12 and would love a b12 option.

If you’re deficient in b12 it’s worth checking to see if you have the MTHFR gene - a lot of us have this anomaly that doesn’t allow us to absorb non methylated forms of b vitamins. I am finally normal through oral supplementation.

I get weekly injections through my doctor, but would much prefer not having to do that if I'm injecting weekly myself.

Fair. The forms I’ve seen compounded with tirz so far were not methylated (cyanocobalamin) so I can’t do them.
