    Traveling With Testosterone Cyp

    Quick question: I'll be driving around a few states the next couple weeks, and my testosterone vial will be stuck in the car for full days at a time on occasion while I'm in the events I'm going to. It's summer so I'm concerned a little with it being in the heat that long. Will it be okay?

    Traveling with Syringes

    I am going on a multi-day trip and that will require two HCG injections. I think I prefer to travel with two pre-filled syringes rather than the vile in case they confiscate anything. If I prefill two syringes, do I leave bit of air in the top? Has anyone used the Frio Insulin Cooling Case...

    TestoGel / Creams etc: how long can you keep a stable serum level?

    I was wondering - Gels etc. have very short half-lives, usually a few hours from what I've read in studies like this one. Would that mean - if I go on a business trip abroad for a few days and happen to forget my gel, I'm in for a miserable experience because after 24-48 hours, stuff has...
