I think your pain tolerance is rather low.
For peptides I use an insulin needle about 10 times, after sticking it trhough the rubber top. I dont recommend reusing needles for IM injections though.
If you dont want to use it, dont. But it can easily be done.
I recommend backfilling the insulin needle with oil based aas. Drawing with a 30g takes pretty long. Backfilling is very quick.
