Step 5 of 5

Inject your B12

Flat against the skin, press, and hold 5 seconds.

1. Choose a site: arms, legs, or lower abdomen. Subcutaneous means the fatty layer just under the skin.
2. Place the injector flat against the skin and press lightly until the red indicator disappears — that releases the safety interlock.
3. Press the firing button and hold the injector against the skin for 5 seconds.
4. The injection is complete when the yellow indicator has stopped.
