I have 3 vials of test e. that I have had for about 3 years now. I have stored them at room temp. and out of sunlight. Two are unused, one vial is about 3/4 full from the end of my last cycle about two years ago. It still looks the same as when I got it but just want to be sure its ok for use. I will be giving it to a friend and want to make sure its safe.
