Is anyone familiar with the ECA Stack (Ephedrine, Caffeine, Aspirin)? I heard a guy talking about it at the gym the other day, saying that he is using it to lose weight.
I thought Ephedrine was banned, because it would speed up your heart rate, and does ECA work better than other fat burners, such as HRX? Has anyone used ECA before?
If someone could provide me with some information I would appreciate it, and if this topic has already been discussed in previous threads, I apologize.
