winstrol depot injections

i am doing my first cycle on winny and i wanted to know where to inject it (is it only in the glutes?) also how quickly to inject and finally what size needle to use. Im inexperienced really i did 1 cycle on deca but the injections hurt for days (i know know it was because i did it too quickly thanks to reading posts here!). any help or info would be brilliant.

I think winny shots hurt a lot worse than deca so I all ways go in the glute.
20 or 22 would be fine. dont forget to shake your bottel watter based steroids will separate.
