The usual dose for pernicious anemia-associated vitamin B12 deficiency is 100 mcg given as an injection into the muscle or under the skin once daily for 6-7 days.

Is vitamin B12 injections subcutaneous or intramuscular?
Cyanocobalamin is usually administered by IM or deep subcutaneous injection. If the drug is administered subcutaneously, care should be taken to avoid injection into the dermis or upper subcutaneous tissue. Because the drug is excreted more rapidly after IV injection, the IV route should be avoided.

A 1” needle is sufficient in adults weighing 130–152 lbs (60–70 kg). A 1–1½” needle is recommended in women weighing 152–200 lbs (70–90 kg) and men weighing 152–260 lbs (70–118 kg). A 1½” needle is recommended in women weighing more than 200 lbs (90 kg) or men weighing more than 260 lbs (118 kg).
What happens if you hit a blood vessel while injecting?
Injecting a blood vessel can cause serious complications in rare cases. However, the likelihood of hitting a blood vessel in the subcutaneous fat is extremely rare. More than likely, if there is blood, it is from slight bleeding after the injection.
What happens if a subcutaneous injection goes into the muscle?
However, subcutaneous injections can cause abscesses and granulomas. Muscle is probably spared the harmful effects of substances injected into it because of its abundant blood supply.
Can an injection hit a nerve?
Injections that occur below the deltoid muscle can hit the radial nerve and injections that are too far to the side of the deltoid muscle can hit the axillary nerve. If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.
