You can get injectable B12 used for cattle. Syringes at Walmart or Amazon. Get the 1/2 inch.
I occasionally inject right below neck or into shoulder between the blades.
I have had acute hypertension and this will limber you up within seconds and your entire neck/ shoulder area just go limp and relaxed .
You cannot overdose so no worries there.
It only hurts if you reuse the needles.
I have a continual low grade pain in my left wrist. would a b12 injection help that? If so where would you inject it.
Appreciated. I was curious about the injection site. Thanks.
