You might look up compounding pharmacies in your neck of the woods.
Strohecker's is great, very reliable, quick to ship. I don't remember what shipping company they use (go with what Noxdraconis says). I wrote them a check the first time I did business with them, but of course that adds to the turnaround time. I paid by credit card the second time.
I have only had a few T prescriptions, but I've never been told it was backordered.
If you can, it's good to stay ahead of your prescription--that is, have some spare T in a safe place. In my fireproof safe, I keep some needles, some swabs, and a vial with a few doses. When I come to the end of my now-full vial, I will use up the stuff in the safe and then replace it.
I figure that if my house burns down or someone breaks into my house and steals the backpack with my regular T supplies, my backup supply will last till I can get new scrip.
