Always good to find out BEFORE you buy something
However from what I can find it claims its ingredients are:
Dicalcium Phosphate: 55mg
Its a pretty standard pseudo ECA stack, very similar to one I document in my guide:
It wont be ephedrine, but likely to be Ephedra or Ma Huang - which is basically the plant. THis is particularly true as there is 40mg in each. THis much pharma eph would not be a great first experience.
The ingredients are explained also in the above article, so rather than just copying them across - pop over and have a look - more info as well.
