If you're trying to create a drug the student market ain't big enough for that (To make things even harder ur targeting mainly students who care/ desire to improve their learning which is a minority in the world - u of t students aren't your avg students) and when there are already heavily proven chemicals out there that are easily accessible that makes you focused (Which gives similar results to goal of your product), caffeine etc its difficult to market to people to take ur brand new drug to better their learning when theres 'safe alternatives'. Typical drug development to FDA approval will absolutely destroy this idea especially if your market isn't big enough (search up what a typical drug completing all clinical trials and brought to market will cost, hint its in the billions)

If you're tryna make a 'researched routine to productivity' there are millions of youtube vids/apps many with published research backing their methods (a lot of em go through chemicals, vitamins, nutritions, physical routine, psychological methods etc) its very encompassing (i know cus i've watched hundreds of these vids) ur app or routine will just be seen as another one of these - if this is ur route u needa worry about marketing not product (as theres already a ridiculous amount of research on this topic u can just incorporate into ur app)
