Hi guys I might be doing a first time cycle soon and I just was wondering about something I am going to get a vial that is 10 ml 300mg/ml of test ethenate
so I if im doing 300 mg a week for 10 weeks and I take 300 mg out of the vial with the needle once I puncture the rubber top thing to take 300mg out do I need to put a new cover or something on it or do I just like use the same whole to withdraw 300 mg again? cuz I am assuming that it will not be clean enough or something after I withdraw 300mg out.
