I understand that testosterone has a shelf life, I am trying to understand what would make it weaken (ie temperature, light etc). Would injecting air into a vial weaken it? I experimented with injecting air into the vial a few times (maybe 5) to see if it would react with extra components in it as I was wondering if they were giving me side effects. However, sometimes it feels like my testosterone isn’t as strong, I wonder if this could weaken it or maybe it’s just in my head.
