I have been using my b12 ampoules 4 months now since expiry date on them ,Im down to twice weekly shots now and perfectly fine so I will continue to use them and if need be I will increase my frequency but as I said Ive been perfectly fine
That means at each shot should be at least 5,000mcg of methylcobalamin NOT cyanocobalamin
We will start the return transfer to the town of Villamar without before making a change of vehicle in Uyuni
