bro, first off for your blood levels to be stable using prop you need to inject eod at the least. you should avoid injecting the same spot twice within the same week.it'll keep the sorness down to a much more bearable level if your prone to that pain. rotate your favorites ie-if eod: mon-l glute, wed -r delt, fri-l quad ,sun-r glute, tues- l delt, thurs-r quad,sat- l glute, etc.....
you have to get a little more creative if you plan on injecting ed.
use a 1.5 x23 or 25 for glutes, 1" for everything else. i use a 1.5 for everything just dont push it in as far for chest or delt shots. but to each his own. good luck.
