>"but it's not yet something your doctor would prescribe you."
Because it doesn't require a prescription. There is nearly unlimited information on the product (including efficacy), and I can go into any pharmacy in North America and buy it off the shelf, no questions asked.
>"particularly when there are no patents"
The idea that you can't make money without owning the patent on something flies in the face of everything done in the hacker world, doesn't it? I don't buy into that theory, but can't really back up my opinion. The world is filled with companies who sell commodity products at a mark up, though.
