I have about 8ml of Test left in a vial from my cycle that ended last September. Should I toss this or is it still good to use? I was going to start my next cycle with it but I figured I better ask in case someone has had a bad experience with these left over vials. For the little I took from this vial, I wiped everything with an alcohol pad before use. It has been stored in a sealed case in a dresser drawer since.
