I saw that one the show too and, while a little risky sounding, it appeared to be difficult to dose and assure that you were getting the same med for the same purpose in the same chemical formats.
SO, before delving into this while side of prepping, I decided to see how hard it was to get the real thing online. I had a tumor in my throat that killed my thyroid a couple of years ago. As a result, i have to take Synthroid for the rest of my life. If I don't take it, it can kill over the long term.
I simply googled Synthroid and found many companies (mostly in Canada) that would sell it. They asked for my doctor's info and charged my visa card. 2 weeks later, I got a small box with 9 months worth of Synthroid sitting in my living room.
The best part.....THEY NEVER CALLED MY DOCTOR FOR VERIFICATION!! :-) I know because he's a former CHL student of mine, so I asked him.
In order to test this, I decided to get another 3 month supply from a different company. The exact same thing happened! They asked for my dr's contact info and then never called them!
Lesson: Try to get the real deal first. There are plenty of companies in Canada that will sell it to you
