I use really small/short needles since I inject one thing or another almost every day.
For T injections, I use 29g 1/2" 1/2cc syringes in my delts. It's a little slow drawing and injecting but it's not a race.
For injecting HCG and B-12, I use 30g 5/16" 1cc syringes in abdomen.
I get them from HealthWarehouse for about $17 each per 100 count box (SureComfort). The needles stay nice and sharp, and if you have sensitive skin then injecting after taking a shower makes it completely painless.
