What is the most powerful energy supplement in the world?

I have tried many supplements such as no-xplode, monster, redbull, 5 hr energy, hoodia shot(which was pretty strong). I think the spike shooter energy drink is the craziest thing i have had to date. Redline energy drink is pretty strong too tho and will really make up pumped up. I haven't tried redline power shot, or vpx meltdown line.
