Never inject back into a vial with a dirty needle, the chances of contamination is too great. Maybe some will say it's okay because the needle is clean, but once you use a syringe it would make me afraid to put anything back in that vial.
Ok - is the delt not a good area to inject? Using 29g .5" 1ml insulin syringe right now.
I have seen on other forums to "not use 1ml syringes", but instead use .5ml syringes. Why?
Is the .5" insulin syringe long enough for the quads?
Should I try SC injections with the test cyp? If so, same process and location as my HCG?
