I'll stick with my 5,000mcg methylcobalamin lozenges that cost a fraction of that and do the job just fine. I'd exercise judgement when it comes to purchasing from a company that charges an extra benjamin for an OOH FANCEH vial with 3 more doses in it and an extra 25c worth of B vitamins. Just sayin'.
I'm also not sure what the policy is on posting links to injectable B-12 is as it technically isn't something we in the states can purchase OTC. But I'm sure a mod will chime in on that if need be.
