Just started testosterone enanthate injections, and I have a question about needles. I have quite a few 22-gauge syringes, that are of course single use only. At the risk of being yelled at, why couldn't I use a syringe more than once? I use the needle only on myself, and I always clean the injection site and the top of the bottle/vial with rubbing alcohol. After the injection, what if I were to draw up a full syringe of the rubbing alcohol, squirt that out, and then recap the needle? Couldn't I use the syringe on myself again?
