Introducing MuscleTech EuphoriQ™ and Burn iQ™: Powered by enfinity® Paraxanthine
NEW Muscletech EuphoriQ™ Pre-workout and Burn iQ distinguishes itself from the rest by including enfinity®, an exclusive caffeine replacement made entirely of paraxanthine - the most powerful of three metabolites of caffeine (paraxanthine, theophylline & theobromine).
By supplementing with purified patented and study-backed paraxanthine in the form enfinity®, we skip the metabolic process altogether, helping to eradicate several detrimental caffeine-related consequences. This results in a remarkably clean, smooth energy and cognition, leaving jitters and crashes in the dust. This is the biggest breakthrough of stimulants in ten years and features in THREE new Muscletech products - EuphoriQ™, Burn iQ™ Powder and Burn iQ™ Capsules.
What is paraxanthine?
Many of us consume caffeine daily, primarily because of its ability to reduce tiredness and enhance mental and physical performance, making it a popular ingredient in pre-workout supplements. However as sports supplements have evolved, there have been mixed feedback from consumers about caffeine, especially as the supplement industry previously advocated for high caffeine doses, which are now being reconsidered due to the associated side effects that some products can give (including jitters and crashes). To understand why paraxanthine provides a solution, it is necessary to understand how caffeine is processed in the body first. When caffeine enters your body, the liver processes it into three metabolites: paraxanthine, theobromine, and theophylline, paraxanthine being the most abundant.
Looking further at these metabolites and their impact on human biology, it's clear that the benefits people seek from consuming caffeine are mainly attributed to its primary metabolite, paraxanthine, rather than caffeine itself.
Paraxanthine: the upside of caffeine, without any theobromine or theophylline
The other two metabolites, theobromine and theophylline, are associated with the negative effects of caffeine consumption, in particular their prolonged half-lives. While the average half-life of caffeine is roughly 4.1 hours (although this can vary significantly depending on one's genetic makeup), theobromine and theophylline's half-lives are about 6.2 hours and 7.2 hours, respectively [70]
Since theobromine and theophylline are also stimulant methylxanthine alkaloids like caffeine, the extended half-lives can pose a problem. For instance, if you consume a high dose of caffeine at around 4pm to prepare for an evening workout, only about half of the theobromine and theophylline would be eliminated from your system by 11pm, which may result in poor sleep quality.
Paraxanthine, on the other hand, has a much shorter half-life – only 3.1 hours.[70]
Paraxanthine is cleared from your system at a rate that is twice as rapid as that of theobromine or theophylline. This presents an opportunity to mitigate the downsides by targeting our consumption of caffeine-derived alkaloid metabolites to only paraxanthine, and as a result, we can reap the benefits of caffeine while experiencing fewer adverse side effects.
