but b12 injections What Should You Know About Vitamin Injections? MIC B12

This syringe includes a passive needle retraction feature that eliminates the need to recap, reducing exposure and further lowering contamination risks

It deserves the best

However, it is not FDA-approved for medical treatment or injection, and regulatory status may vary by use

hi I find it very easy to reach either arm but admit people do ask me that,I cant see why it would be a problem I just sit on end of bed with stuff all laid out on a clean towel and sharps bin handy,draw up b12 with a red filter needle,personal preference here,then discard and do the injecting with the orange needle , if the b12 is cold or you do have a bead of it on injecting needle then yes your right it can sting but again that is a rarity for me
