My doctor wants to put me on a weight loss program requiring b12 shots.Do they work?And How? -

Is it harmless?

Ok I cant explain how they work because I never really went into that side of it but they do work. they are good for you in many ways and the only side effect I have ever seen is one very sore but from the injection. I mostly used them to clear up roid acne and lose a bit of fat I picked up.
