I borrowed some test e from my friend and put it in my empty test cyp vial. The old vial had a very few drops of test cyp left. The solution is now kind of milky in appearance. I tried placing it in boiling water and it clears but gets milky again after a few minutes. Have I trashed it?
Moisture. It won’t kill you(hopefully) but probably wouldn’t be considered sterile anymore.
That depends on how badly you need it I guess/how fast you can get more. The safe bet would be to chuck it.
