Bob, I'm sure your clients would love it if you charged them to field test unproven stuff for you. In fact after talking with the ErecTech drug representative, I think we have a whole new side business for you.

The drug rep said he'll pay you $50 for each two person guided trip. He'll have you give one client a placebo, and the other the experimental drug. After that all you have to do is make note of which guy had nausea, vomiting, and/or diarrhea, and which guy had an erection.
