Need help 4chan...

Want to start a paid clinical trial cause am a poorfag, however I frequently get heartburn and need to use PPI's or antacids, which is something have hidden from the research team... Anywho I know it ain't gonna affect anything but obviously I don't want them to figure out that I have taken PPI's when they periodically draw blood (clinical trial will be a couple weeks long).

But it shouldn't really show, since they won't be looking for it, right?
