Well I have used JetClean and compared to to other 1, 4 bute products, it sucks big time! And I'm not the only one to have claimed this. I do veleive it does have the ingredient 1, 4 bute in it, but something is wrong, like it's watered down or something, cause the effects are so weak. Plus it's a rip off, compared to the 1, 4 bute you can get from An**al, which is not only cheaper, but more potent.
