"5-deoxyadenosylcobalamin and methylcobalamin as sources for Vitamin B 12 added as a nutritional substance in food supplements: Scientific opinion of the Scientific Panel on Food Additives and Nutrient Sources added to food"

The only requirement is that the drug gets delivered via the subcutaneous or intramuscular route, not intravenously

I always warm the ampoule before injecting ,tuck in my bra or waistband while Im prepping all the other bits,I dont use swabs as I know I don't need them ,nurses also don't use them often these days,they tend to sting unless the swabbed areas completely dried before injecting
