Do some research online. You can purchase the b12 online and the get your Dr to write u a prescription for the hypodermics, then give yourself the shots. Some guys I used to work out with back in the day would inject b12 along with the performance enhancing substances.

My MIL gave herself injections of B12. I have no idea where she got the stuff or the needles. This was during the late seventies and early eighties; so things were probably a lot different back then.
