I know eca is ephedrine + caffeine. I shopped around and found Ephedrine multi action w/25mg ephedrine and 200mg guaifenesin. I was told here that the guaifenesin was a expectorant or something, but is this only half of what I need? Do I now need a caffeine pill?
So when one says "eca stack" are they reffering to 2 pills? Thank You
