I took my last testE/EQ shot on Wednesday morning last week before leaving for the states. I just got back late last night so I was just about to take my next shot now, Tuesday night, but I just realized that I forgot to get more injecting needles and I've only got the one I used last time. I still have a few unused drawing needles and syringes left, but the needle place is already closed. I normally inject on Monday and Thursday, so should I just use the injection needle again, or wait until tomorrow when I can buy more?
