I suppose this hinges on one's definition of stimulant. Do we classify a compound based on the end result or do we classify it based on the pharmacodynamics(what it does to the body and via what exact pathways?) Do these comounds cause direct release of dopamine and norepi? Perhaps not and that is why the "non-stimulant stimulating compound" angle is being pursued by the manufacturer????They say a lot of the same things about dynamine as they did about theacrine. Supposedly, neither is a stimulant, but they work by agonizing the dopamine system and antagonizing adenosine receptors. These are also the primary actions of caffeine, which is considered a stimulant. To be honest, I can’t tell you why theacrine and dynamine aren’t stims, but it seems to me that they are. I have no doubt they’ll affect sleep, at least for some.
Personally I like teacrine and have yet to try dynamine.
