Sup guys, i apologize if this is a repeat question but I did extended searching on AR and couldn't find very relevant info on B-12-
I'm curious as to other good sites for b-12 (other than quads and glutes)... also, how the receptor sites react to repeat injections every other day. I ask because i don't want to shoot the stuff in my right cheek, and go back to it 4 days later and end up with my body rejecting most of the b-12 due to overused receptors.
*disclaimer: i know the term "receptors" might not be the right term to use
any info is appreciated
