Digital-Pie Rat and everyone else:
Xenadrine is widely believed to be the best fat burner out there - it has the widest range of fat burning compounds but lacks Yohimbe HCL (which is better used topically, anyway) However, Dymetadrine Extreme is DEFINATELY more potent, you feel more wired and "psyched" to work out or run for like 4 hours but my experience is that you come off of the "high" faster and reach a deeper trough (feel sluggish, have a urge to "take one more pill", and feel insanely hungry if you dont take it again 3-4 hours after your last dose) Overall, though Xen is best, it has a more regulated effect, lasts longer, and contains a wider variety of compounds... In addition, I'm tempted to believe that your body would respond more to it over time because of its variety.
Anyway, Xen goes for $30 plus shipping on average for 120 caps. Lets just say the average on the net is $30/120caps. Well, Costco sells a version from Nature's Origin called Xanatrim and states on the label "Compare to Xenadrine". I found Xanatrim to be exact in its dose and ingredients to Xenadrine and it sells for $16/240caps... Thats like 1/4 the price. Hope you have a Costo membership, if not, search on the net and see if you can find that manufacturer. BTW, Dymetadrine goes for $20 plus shipping on average for 100caps, but you only take one cap/serving versus 2/serving for Xen/Xan (but need to take it more frequently, say 5/6 times a day). So for arguments sake, lets say someone would take 6 Xans (2/dose, 3 times/day) or 6 Dyms (1/dose, 6 times) a day [both cases are pretty extreme, tho - immediately taking a dose when you wake up till 5-6 hours before sleep @ midnight] The end result is you pay WAY less for Xanatrim from Nature's Origin versus Xen/Dym and difference between them all is too little to pay more or in Xen/Xan's case, no difference at all.
Obviously, getting ahold of Clen/T3/Yohimbe HCL/DNP, some VERY good knowledge on on their sources/uses/disclaimers/applications, would be the absolute biggest PUNCH in fatloss, but these are for all the extreme peeps. Price/Performance, though, XANATRIM is best hands down.
I hope this puts a damper on all the "which is best" confusion, or at least clears it up. If ANYONE wants to add their point of view, PLEASE post your thoughts on brand/dose/price/performance of fat burner because I'm sick of all the ADVERTISEMENT Hype in the magazines and on the net regarding fat burners. Let's clear the REAL from the B/S and get some dialog on this topic.
