I was thinking of switching injection sites, but I'd like to get some feedback from some of you guys. I'd like to know if anyone here has done injections into the bi? If so does it hurt, is there any special recommendations? I have gone to spotinjections.com Looked @ it, but I'd like some feedback, please help. If you don't inject into your bi, where do you recommend another place that wouldn't hurt. Im currently injecting my glute(left side). But its getting kinda sore now, like to switch up so the receptors are fresh? Any suggestions would be great! Thx!
