So, I have the needles and my B12 arrived from Germany yesterday. I ordered Vitamin B12 Depot Hevert Wirkstoff:Hydroxocobalaminacetat 1000ug. My Doc gives me an injection once every 3 months, however since my loading dose, I know I need them more frequently, but he wont budge, so I have had to resort to self injecting. How do I know this stuff is safe? I read lots of forums and other people have recommended this source, but, how do I know what I am actually injecting is what what was ordered? It looks the real mccoy!!!
