Yeah if you got a gut and is hard to see what you are doing, maybe you are not hitting the spot very well.
Not sure what advice to give on that except that when you got the needle all the way in where you think it should be, it should NOT take a lot of pressure on the syringe plunger to inject the fluid. If it does take a lot of pressure (do a test injection 'into the air' using plain water -- that is how much pressure you should need) then you are in tissue and not in the Corpus C.
When i inject I don't hold it out straight i bend it over flat to one side or the other and inject that way -- like using your pubic bone like a operating table! But if you have fat pad that might not work either.
How long would it take you to lose the gut?? Then you might have an easier time??

Well, try the plunger pressure thing first and see how that goes .... also I don't JAB it in quick ... i work it in reallll slowww and ... well it is not as excruiating as it sounds ... no pain really .. but you know you are in the right spot cause the needle goes and the resistance reduces when you go thru into the Corpus C.
But that feel is less precise than the plunger being hard or easy feel ... so go with the plunger feel the first time.
AND if the plunger feels way too difficult, you can try continuing to push the needle in more (dimple into the skin even) and try pressing plunger again and see if it feels easier. Always works for me.
