There were so many versions of Mesomorph actually finding the "OG" would be hard, you need to know what to look for...anything Jared had his hands on was either an extremely weak version of DMAA or not DMAA at all. None of their pre's gave the effects that people experienced with the originals...that of course can be another 300 post thread discussion for another day...or one we've exhausted over the years.
Same with Dust Extreme...you have to know what to look for to get the OG version i.e. the Sour Gummy Bear and Pineapple Mango were the OG flavors that hit hard...the flavors after had the "reformulation" per se, Passion Fruit, etc. and the serving size changed to 25 from 30. The reformulation "still" supposedly contained DMAA but wasn't even close to the OG Dust Extreme.
