Necessity is the mother of invention.
I have been using a 23g 1" with a 3cc syringe to inject into glutes, and draw fluid.
I have been using a 27g .5" to with a 3cc syringe inject into quads and delts.
I failed to notice that this would mean that I would be ripping through 23g needles at 4x the rate of 27g. I realized that I was going to run out out of 23g before the end of my current cycle.
As a desperate measure, I warmed up my vial of TP in some warm water for 2 minutes before injecting. I would guess it was no warmer than blood temp. Then I tried to use a 27g .5" needle to draw and...
No issue. Not even particularly slow. If you run into a similar situation, feel free to use small guage needles to draw.
If it wasn't for this board, I'd still be going 19g into everything.
