what type of injection is b12 Hydroxocobalamin Injection: Vitamin for Energy & Anemia Vitamin B12 for Injection Cyanocobalamin

5-Amino-1-methylquinolinium, CID 950107

To inject Intra muscularly (I.M.) I use a 2ml syringe , although the ampoule is 1ml This ensures that I get every last drop of precious B12 into the syringe .I use a long 1 1/2 inch needle to extract the B12 from the ampoule

Every order is processed, inspected, packaged, and shipped by our in-house team instead of being passed off to a third-party logistics warehouse

All I can say is that I'm basically a case of a doctor being indifferent by recommending a patient take vitamin b12 tablets in addition to b12 injections...which allowed a severe reaction to take place that is ongoing
