Loaded up my save near the end of the game and went to the U-Invent, only needed the Electric Gel... actually surprised that I've never purchased any anyway! THANKS!

Hacking the U-invent will reduce all requirements by one, and the tonic "Clever Inventor" will reduce it further, but you will always need a minimum of one of each ingredient. The tonic "Scrounger" will make it easier to find the right ingredients. The only way to check your inventory is to visit a U-invent.
