E = ephedrine C = caffeine A = aspirin
i.e. this is a thermogenic fat burning stack, similar to every other one on the shelf. like xenedrine, hydroxycut.. etc.
Can also be
E = Ephedra (from Ma Huang or other herbal sources) C = Caffiene (from Guarana or other herbal sources) A = Aspirin (from White Willow Bark or other herbal sources)
These are what are typically found on the shelf. TwinLab Diet/Ripped Fuel, Xenadrine, Hydroxycut, etc.
Most are formulated to deliver 200mg Caffiene and 20-25mg Ephedra.
Dont exceed 100mg Ephedrine a day unless you are a very large individual or have built a tolerance (in which case you should stop anyway). I've heard it takes 12 weeks for the bodies receptors to adapt to the ephedrine, at which point it will cease being effective at the current dose. This is when people push their dosages up and that can cause problems.
