Hi - what would you be using these for, a general supplement?
I give myself B12 injections but it is because I have pernicious anemia and it is the only way I can absorb B12; my body does not absorb it from any food or oral supplements.
And it makes a world of difference. I no longer feel like I am going to die. That kind of difference. Now this is prescription B12, prescribed by my doctor on the basis of my test results which show me to have pernicious anemia, and it's not something I order over the internet.
