I have 12 (1x8 + 1x4) ampoules of hydroxocobalamin (1mg in 2ml - Depot Hevert, bought from amazon.de) and 9 ampoules of methylcobalamin (1mg in 1ml from B12d.org) that I don't want.
I found the 2ml injections were slightly uncomfortable and I had some mild side-effect from the methylcobalamin. So I'm going to stick with my 1ml hydroxocobalamin injections.
Rather than throw them away I though I'd offer them to anybody that might want them. Just send me a PM, saying which of the three you'd like and I'll send them off.
