Which is the one that hurts like fu... when administered?

Well, the B12 they inject is inorganic chemical vitamin. To get the real thing organic and natural B12 is better from food products which will have no side effects.

My mother used to have them because she suffered from pernicious anemia. She always mentioned feeling tired about the week before the next injection. You might mention that instead of once every three months you have an injection every two months and 3 weeks.

I had a B12 shot, and it didn't do a thing for me. It just felt like I had a shot with nothing in it.

hoax.
