B12 Dosage & Injection Instructions
Inject 1cc (100 units) once a week by Intramuscular administration.
Inject B12 by Subcutaneous (Sub-Q) or Intramuscular administration. Injecting Sub-Q is the easiest method since it is injected in the belly fat. Here is a video showing the Sub-Q injection site (it is the same as the HCG injection):
Intramuscular (IM) injections are given directly into the central area of the deltoids (shoulder). A needle is inserted with a quick thrust at a 90-degree angle. The needle penetrates the skin and subcutaneous tissue, and the medicine is deposited in the underlying muscle. The deltoid muscle in the upper arm is the preferred injection site for IM administration.
