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. Many have tried. Numerous stimulants have been introduced. Not until now has a company successfully produced a product capable of replicating the performance of the ECA stack.

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.

This amazing compound is a NEW discovery by AMS. This innovative company has just locked down a long term licensing agreement to ensure that this key compound will be available in its strongest form.

AMS is known almost exclusively as a muscle-building component company, they knew that if they entered the world of fat burning - they needed a game changer!

So many reputable supplement companies have tried to mimic the fat burning effects of the ECA stack - only to fall short. Either they didn't pack the energy punch of ephedrine or they couldn't reach the fat burning effects...sadly most products failed in both categories.

It's been a long while since a legitimately NEW stimulant has hit the market. Let's take a look at the new compound and see what makes it so special and why it is a TRUE replacement for ephedrine. First, it was tough to find a naturally occurring alkaloid that was similar to ephedrine. Synephrine was close in structure, but failed to give the energy boost of ephedrine. Geranamine was a good try, but didn't really provide pack the weight loss punch expected. PEA looked good on paper, but didn't really deliver the long-term effects desired. Even though these products are decent stimulants, the world just wasn't happy with them as TRUE ephedrine replacements. Second, the new stimulant had to hit hard like ephedrine without causing the increase in blood pressure and occasional heart- related effects. This was probably the toughest part of the challenge in finding a new stimulant that really worked like ephedrine. We needed something that was similar but didn't cause these risky side effects.

Ladies, gentleman and stimulant junkies - AMS gives you Halostachine! This stimulant fits the bill perfectly. When you take it, you will know why we think it's more potent than ephedrine, milligram for milligram and without the negative side effects like the massive blood pressure spikes associated with ephedrine.

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 negatives 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.
