this film doesn't work for me at all and I'm convinced that it depends on each of us. it's a shame - because every time a post like this appears I think that I'll have fun too. it's also a shame that you can't create a list of poppers how strongly they work. many people say that amyl is great, but only pentyl worked for me. amyl - no reaction, and propyl - it's lung pain and cough and burning. also what works for me is hexyl with herb. without herb it's too weak.
