2thick,
I inject on the exact side of my quad, but the same place between my hip and knee.
I have been doing it like this for a very long time now, I notice your pic shows it going in closer to the front of the quad. Is it better to do it like the pic shows.
As for everyone else, the bicep injections aren't shit once you get used to it. The first one you do in each bicep is kinda bad, but once you get the hang of it you start to look forward to doing them.
I have been alternating right shoulder, left shoulder, left bi, right bi with winny everyday for the last 6 weeks. I am not exaggerating when i say my biceps have alot more peak on them, and my shoulders are coming out a bit more. The biceps are the most noticable though.
