I have cyanocobalamin B-12 prescribed from my doc and I'd like to know the best dose for how I mix and administer my hCG : I use 2mL of bac water per 5000iu of hCG.

The vials are 1000mcg/mL. (1mL vial). So if I mix in 1mL of water with it (to get to a 2mL dilution), I get 1000mcg/2mL or 500mcg/mL. If I take my usual hCG dose of 250iu/0.1mL EOD, that means I'm getting 50mcg/0.1ml of B-12, EOD. Is my math correct? And is this an okay dose of B-12 to take EOD?
