PJH said I have tried this also. Unfortunately I got nothing from it...
At what dose did you try it? Most users tend to really enjoy Demiurge whether for getting work done or training. To be honest, it's by far my favorite nootropic and makes studying for pharmacy school a breeze for me. I'd recommend giving it another try possibly at a higher dose as you may need a little extra. The added focus is wonderful and most people really enjoy it.
