A few years ago I took an ECA stack for one day and couldn't bear it. Just half the recommended dose would leave me shaking like a leaf and feeling like hell with nervousness. After hearing about how Coleus Forskohlli added to the stack could reduce or eliminate the CNS stimulatory effects, I decided to give it a try. I used Diet Fuel Ultimate and strangely enough I took the full dose(3 caps) without the CNS side effects. I felt a some stimulatory effects but it was not a nervous energy like I had experienced when I took plain ECA. Has anyone tried this and gotten the same reduction in stimulation?
