I received bottle methylcobalamin from B12 charity. it is 1mg so 1ml per injection. I want to try SC injections as I have nobody to show me and worried about IM. What size needles, syringes do I need. I have read on this forum that using insulin needles, the needle can get blunt when putting in the bottle to draw methyl. Is it best to use a different needle for drawing and then injecting or will it be ok to use insulin syringes to keep it simple. I assume I cannot use an insulin pen because these are specific to different insulin medicines. Any advice is appreciated. Is there a good video to show me what to do. If anybody is a nurse and willing to show me over Skype that would be wonderful as i am a bit apprehensive doing it the first time.
