There's more dramatic license than just that - if you inject yourself into your behind, there's no way a "pressurised stream of blood spurted halfway across the room". Not going to happen.
I have the "fortune" of having to do injections in that place every week for several years running now, and I'm far from handy with a needle. The worst that ever happened was a thin rivulet. And that was dramatic - usual is nothing, or maybe a drop or two of blood.
Based on that part alone, he's dramatically exaggerating. Combine that with having every side effect in the book, and my money is on this being made up in large parts.
I have been a Type I diabetic for the past 15 years, and have had the "pressurized stream of blood" that shot across the room a handful of times when injecting my stomach. Granted, being an insulin dependent diabetic, I have given myself an estimated 32,000 injections, which I seriously doubt a steroid user would ever get anywhere close to.
You've got larger arteries/veins to deal with in the stomach area. The buttocks are fairly light on them, and unless you move close to the center, there's nothing with high enough pressure to spurt.
I guess this is possible if you hit an artery. That's why you do a suction movement before injecting, because if you inject steroids there, you're dead.
