It has EGCG, EGC and ECG and probably other stuff in it.
It's the EGCG that's the daddy in this though - for content really, since the other two are only present in lesser quantities.
Quick (very basic) biochem lesson for you:
Ephedrine causes adrenalin/noradrenalin (A/NorA) release into the synaptic cleft causing all the gravey stuff for fat loss that it does (on the SNS and adrenergic system).
The body takes some of the A/NorA back into vessicles for storage, while the rest is metabolised by MAO-A and to a lesser extent, COMT.
Yohimbine is an MAO-A inhibitor, so allows the A/NorA to stay in the synaptic cleft a bit longer (more excitement and thermogenesis).
EGCG inhibits COMT, again, allowing a bit more stimulation - but like i said, COMT only plays a small role compared to MAO-A.
Overall, an EC/Yohimbine/green tea stack is quite a potent little beast. Potentially dangerous if you go over the top though, as far as blood pressure and heart rate goes.
I just drink a cup or two of green eat every time i take EC. And the occasional cup when i don't.
