LOL .......Just kidding, that was only a joke!!!!
No, B-12 injections will have no affect on buttocks size. That is unless of course you start to gain weight, in which case, you may gain a little there as well as everywhere else. B-12 shots are typically given to patients with B-12 deficiency, such as in patients with malnutrition, chronic disease , neuropathy, immunosuppression, and for patients who are producing insufficient number of blood cells. It should have little to no affect on your buttocks.
