B-12 can be used both IM or SQ. Either way works fine but I would rather SQ. Clinics usually use it SQ with thier patients

"Pernicious Anemia: Parenteral vitamin B12 is the recommended treatment and will be required for the remainder of the patient†s life. The oral form is not dependable. A dose of 100 mcg daily for 6 or 7 days should be administered by intramuscular or deep subcutaneous injection. If there is clinical improvement and if a reticulocyte response is observed, the same amount may be given on alternate days for seven doses, then every 3 to 4 days for another 2 to. 3 weeks. By this time hematologic values should have become normal. This regimen should be followed by 100 mcg monthly for life. Folic acid should be administered concomitantly if needed."
