I am also on the micro lupron protocol so i can tell you what I use if thats any help??
For the microdose Lupon (i do 20 units) i use the insulin syringe 1/2cc with a 29 gauge 1/2" needle
For the Menopur i use a 1ml syringe, add the Q-cap, draw up the dilutant then add it to the powder, mix and repeat as necessary (adding powders). I then inject with a 27 gauge 1/2" needle
PIO is different and i havent done this yet as last cycle i used suppositories instead, but from my med training i can see i use the 3ml syringe, mix it with the big fat needle (18 gauge 1 1/2' needle) and inject after changing the needle to the smaller (but still unpleasant) 22gauge 1 1/2" needle.
Remember my RE might have given different needles etc, but hopefully this might help
