-I was wondering about the 18g needle,can i leave the 18g needle in the vial,stuck in the rubber ,so i dont have to keep changing needles every time to draw and than inject? just basically leave 1needle in the test vial and 1needle in the eq vial? what do you think?
-About the syringe since im using 18g needles and 23g needles,as for the syringe itself(NO NEEDLE,some people get confused so i detail this part out) can i use the same one for the whole week if im doing injects monday TEST/EQ and thursday TEST/EQ can i use the same syringe but just a new needle
or should i use a different syringe each time?
