Remember the legendary ECA stack? If you don’t, it was probably the most effective weight loss/energy/stimulant product this industry has ever seen. Its components were – Ephedrine, Caffeine and Aspirin (and later – replaced by White Willow Bark). Since its dubious departure – no fat burning products have been able to replicate its performance.

Advanced Muscle Science has recreated the hallowed ECA stack with the only compound to approach the strength of ephedrine in stimulation and in fat burning capabilities ... Halostachine.

Halostachine is patent pending and only available in Vapor-XT, which means you can’t get this in ANY other supplement. Halostachine works by giving your body the peak mental stimulation of ephedrine as well as Beta 3 stimulation without spiking blood pressure. This means it delivers all of the benefits of ephedrine without the negative side effects. In studies, Halostachine is almost twice as safe as ephedrine while still showing the massive fat burning potential once coveted by ephedrine users. Halostachine is more potent than ephedrine, milligram for milligram and without the negative side effects like the massive blood pressure spikes associated with ephedrine.*

AMS took this powerful new stimulant and mixed it with the classic CA stack (which is caffeine and “aspirin” in the form of white willow bark), giving you the new HCA stack. This stack is something available only in Vapor XT and is unlike anything since ephedrine.
