They all sound kinda different, like some will be loud, high pitched, and faster, but most of the ones I enjoy are really slow, deep, and soft. Here's a sample of what most of them sound like. It's 100% a scam, unless you're into the placebo thing and you actually believe the doses will work on you, but even then it's all in your head. If you can get your hands on it for fun, then go ahead and play around with it, but I'd never encourage anyone to spend money on it.

It's not because of the dose itself, but more because of the placebo affect, plus it can be kinda hypnotic. I like to listen to it sometimes, because some of the MP3's that come with it are awesome, and it can be very relaxing. It's a great placebo, but it's not going to make you meet god, have a fright seizure, or have a spontaneous orgasm like they describe, and no, paying $200+ for the full program isn't going to have any affect on that.

The only time it ever 'works' is when you want it to. I've been using Idoser since 2012 when a friend first showed it to me, and yea it's all a bunch of bullshit.
