whats on the outside of the vil shouldn't have any effect on the gear itself. did you wipe the top off with an alcohol pad before drawing and then your skin before pinning? Test Prop gives me crippling PIP so I dilute it down to 50mg/ml and pin in each glute. Yea it sucks having to pin twice but it beats not being able to walk for a week.
Yea I wipe with alcohol every time
I was afraid that vial leaking from inside and got contaminated because I have used same patch before it without any problems
