Currently I have only 23x1 syringes my doctor prescribed. I use a new needle and plunger every injection and one needle I keep reusing to draw out t-cyp every time by unscrewing new needle from plunger and screwing in the drawing needle then replacing again with the new after the draw.
My question is, 1) would it be a bad idea to use the same plunger every time and just replace the needle? It seems like when I draw out "X" amount of t-cyp and then replace with the new needle and squeeze the air out, I end up with less in the plunger than I originally drew out. I know this is because I am now filling the empty new needle and barrel with the cyp.
2) Would using the same plunger be unsanitary and not worth risking infection or something else?
I know I would waste less product and it would be way cheaper to just buy needles this way, but really not my main concern.
Thanks
