@reggie..... I'd do 5mg of methylcobalamin orally on an empty stomach daily, for 3 months.
Then get retested after staying off your B12 for a week and see what your new level is.
Shots are not necessary if you do it the way I suggest. You should be over 1000 after 3 months on the oral.
If you test over 1000, you can cut back to 5mg twice a week, or 1mg daily, whichever you prefer to do.
