Has anyone out there used the dried version of Methylcobalamin to dissolve with 10 ml of saline. Every 0.5 of the preparation then contains 1mg of Methylcobalamin. How much is a normal dose of MeCbl? A normal dose of Hydroxocobalamin is 1mg. Is it the same for the Methyl? Am anxious to find out,as 6 months of Hydroxo hasn't helped my numb feet one iota. 10 ml of the solution would provide 20x 0.5 injections of 1 mg strength . Does anyone know how long this could be kept at say 5degrees celsius in the fridge? I think that Methyl is much more volatile than Hydroxo, which doesn't require refrigeration. Would be really grateful for any information. I have the kit now, but not the required knowledge. Thank-you.
