I started on i-doser a few months ago, i did not believe it at first, i thought it was impossible to have strong effects, i'm a Medical student by the way, and the way our brain processes sound is a very complicated thing.
The first dose i tried, just to experiment was alcohol, and it worked more or less, i was kind of dizzy and i was clumsy, a bit happier too. So i thought that it really worked, i was amazed, it was not a very strong sensation but i was amazed all the same to notice that it really worked.
The second was OrgasmQH, once again it worked, and very very well, i felt the vibrations and the sensation, it lasted for a bit and everything, it was very cool and i was impressed. It's a good pasttime to experiment.
There were drugs however that do not work with me, for instance, peyote, and LSD they have very limited effects, i get more calm but nothing more. I Do not have strong sensations with those. Anyway i also tried NitrousQH, in the beggining it worked, my body got warm and i laughed for nothing, i was very happy but it only lasted a few minutes, and nowadays it doesn't work at all :/ That's a pity, i liked it.
Marijuana works, it gets me fairly high

And finally, i tried hand of god! And omfg it is stronger and more intense than all those combined. I had a very very strange experience. I can't really describe it well, i was lied down, in the dark listening, during the 30 minutes i felt warm and some other sensation, nothing really especial. The dose ended, and i thought, what a disappointment, and i decided to sleep for a bit, but to my astonishment the warm came back all the sudden, and much more intense, i felt that something was grabbing me, and pulling (i don't believe in souls nor in god but the best way to describe is:) my soul out! and i saw my damn body lying in the bed (but not my bed, soem other bed in another house). I was conscious but in a dream, kind like if i had been transported to a parallel universe, i talked to people i did stuff and when i went back to my corpse i felt an amazing pull and i wake up, shaking, adrenaline flowing in my veins, i was very hot, excited, my heart was racing. I can't possibly describe how weird it was, it was so real, and so different. I couldn't tell apart reality from dream.
Sorry for the mistakes, i'm still amazed and i'm not from an english country.
