B12 injection

Hello everyone,

Just looking for advice on which needles to use to inject into Thigh IM.

I’ve been looking and it seems there are different lengths and g.

Any help would be great

Thanks

The colour of the needle indicates the gauge (diameter of the tube). They are normally available in different lengths. Most people inject IM using a blue 1.5" needle.

Often I should inject if I am having a trial? Started last night
