I was thinking that those UK folk seem to be all about more even numbers. They only inject 1 or maybe 1.5 mg and no other dose.
I was also thinking how clumsy are these folks that they can dull a needle by touching the glass.
You see the B12 that I was able to procure the USA came in a vial usually 50 ml not a ampule. There is a rubber type disk in the top and the needle is jabbed through the rubber into the vial. Not an issue hitting the glass and dulling the needle.
This also explained how I increased my B12 injections. I had the option of increasing 1 mg at a time.
It was a a am a dumb ass moment. 😜
