I have been sent by a friend in Germany Hevert B12 1 ampule with 2 ml and 1000 ug hydroxocobalaminacetat so normal amount of B12 in double amount of liquid.
I seem to react quite strongly to the other ingredients becoming very red and itch even in my most recent one in leg which I had thought was ok. Unfortunately I have a hundred of these and cannot send them back. Has anyone else used this size? Thank you
