Don't you have a patented prescription to sell? To whom?

If you don't apply for a patent, it will be difficult to sell it. First, if you don't have a patent, how can people believe you? Secondly, drugs must go through clinical trials before they can be put into the market, so people must make sure that they are true. Here comes the third question. If you don't give people a prescription, how will they know if it works? Do people who have given them prescriptions still need to buy them from you? How wonderful it is that you want to make money and don't want to spend money! If your prescription is true, you will be the next richest man in the world. Do you still care about making a patent?
