I've gone back and fourth between Xenadrine and Ripped Fuel for a few years. I'm completely off the speed a few weeks now, giving the receptors a break.
you can buy themodrime an nay general nutrition store or due a search on the web it is over the counter product, but becareful one therm is equal to three ripped fuel. i have used both i used the ripped to taper back.
personally i love this stuff. I've never tried Adipokinetics but i have MD6 (old version) and Lipokinetics. Both are great and from what i hear most people like Adipokinetics better than MD6.
It's sold by Syntrax. They're the only ones who can sell Norephedrine right now ( i think). It's only $22 at Dpsnutrition.
