Supplements and devices are just an aid. They may help you become lucid easier. But if you don't know how to become lucid, they will just get you in the state from which is easier to become lucid, but you have to make the transition yourself and you need to know how to realize you dreaming and all that stuff.

So supplements and devices by themselvs will not get you lucid. You need to read tutorials, practice RCs, mantras and daytime awareness.

Hope this helps. Happy dreams
