H.E.A.T. Stack from Avant Labs:

H.E.A.T. stands for Hordenine, Evodiamine, Alpha-yohimbine, and Tyramine. And, in the right combination, they are far, far more than a clever acronym. While its ancestors, with their focus on only norepinephrine, did wonders for appetite suppression, they were modest thermogenics, at best. And, worse than that, they were all out enemies of the central adipostatic machinery, the Fed State, and they caused hypersensitivity to cortisol and the stress response.

With H.E.A.T. Stack, we have added a superior increase in dopamine and epinephrine to a more moderate activation of norepinephrine. The result is activation of more lipolytic and thermogenic pathways, better maintenance of long-term adipostatic machinery, potent appetite suppression, and strong mood and energy support, with fewer negative side-effects.

To summarize:

* Superior nutrient partitioning
* Superior thermogenesis
* Greater energy expenditure increase
* Superior hunger control
* More leptin friendly
* Enhances mood and energy
* Caffeine free
* Ephedra free
