I was checking into it too. It appears you can get it here without a prescription.

It's not particularly cheap, but if you're going through $10k+ what's another few hundred bucks? In the past couple days though I saw a conflicting article that it wasn't "ready" for HT treatment? I'm very curious as to what that meant, but if I was going under the knife tomorrow I'd definitely grab a box and try it.
