only jokin m8 take no notice of the above advice.as regards to makin your next needle experience better less of a pain in the arse for you,lol.Do you do the injections yourself?If you could get someone trusted to do it for you you could do this as follows.
make sure it is a sterile area,use alcohol swabs before and after on injection area(you might find this numbs the area a little,some ppl say so)
Use a different needle to draw out oil and for injection.make sure all air bubbles are out of the solution.
as the person is doin it is just about to push the needle in get them to blow on the area they are injecting as the needle is pushed in.You tend to not feel the needle breaking the skin if this is done.
Try and take deep breaths as you find this whole procedure distressing,breath in thru your nose out thru your mouth,get nice and relaxed before and during procedure.

a lot more info than I could ever tell you there and also helpful photos.
I'm not sure anyone ever gets used to using needles,I know I haven't but it's just about the best and only delivery system for a lot of compounds so we as athletes/bodybuilders gotta live and persevere if we want to see the results desired.Good luck m8 and for most people it does get easier.
