Caffeine for e-liquid?

[siriuslion]

OK I found caffeine powder, koolada, and sweetener, along with menthol crystals and some stuff to make hot e-liquid hot as in peppers.
Anyway the question is has anybody tried the caffeine and whats your opinion on it?

Some really smart people have done the math and science. In order for you to have any real effect from caffeinated e-juice you would have to pour a thick glop of sludge onto your atty.

Best to just get your caffeine fix elsewhere.

there is a coffee liquid with coffein, but you need to warm it before vaping, and you dont really feel the coffein, maybe a little bit if you havent drunk a coffee in weeks ...
... imho not worth it, and it ruins the attys quicker

I didn't notice anything when i vaped some juice i have with caffeine in it.

I notice it in the juices from vapor renu, but its not a "i just chugged an energy drink" fix, more of a slow drip of caff. I think it helps on days when i have to switch from night shift to day shift, but its not gonna knock your socks off and my observations could just be a placebo effect. However, the first day I vaped it all day my ears were buzzing but that is most likely because I got it in 36mg nic. Never tried it diy, and most likely wont.
