What ingredients are in the pink ecstasy pill with revolver?

Drug compositions change depending on where they come from and who made them. A pink pill in one city can be completely different than a pink pill in another city, even if they have the same stamp on them. The only way to know what is inside the pill is to buy a drug testing kit and test it yourself. There are also websites such as http://www.ecstasydata.org that have some of the lab testing results online from different cities.
