MuscleTech iQ Series Supplements with New Stimulant: enfinity Paraxanthine!

For nearly half a decade, the sports supplement industry has been in search of a new workout stimulant to intelligently — and safely — power athletes through their training.

The pioneers at MuscleTech have found it, and it’s going to turn the dietary supplement industry — especially the energy category — completely on its head.

Introducing enfinity: pure paraxanthine in MuscleTech’s New iQ Series

Its name is enfinity, and it’s a pure form of paraxanthine, caffeine’s most potent metabolite. MuscleTech is pioneering its release, and unlike many other stimulants that are added to caffeinated formulas, this enfinity is here to replace your caffeine!

MuscleTech iQ Series: Introducing enfinity (Paraxanthine)

MuscleTech has revealed their new iQ Series of supplements, and it will include a new stimulant — paraxanthine — named enfinity. Learn how this lineup will forever revolutionize the entire energy industry

MuscleTech is releasing it in three different supplements:

  • EuphoriQ: Pre-Workout Supplement with 300 milligrams of enfinity (paraxanthine)
  • Burn iQ Powder: Smart thermo fat burning powder with 150 milligrams enfinity (paraxanthine) per scoop
  • Burn iQ Capsules: Capsule-based fat burner with 100 milligrams of enfinity (paraxanthine) per capsule

With paraxanthine instead of caffeine, users are noticing a far smoother energy experience, with less of the negative effects generally associated with higher doses of caffeine.

In this article, we show the labels and give a brief rundown of this next-generation stimulant and explain why the experience is so universally positive. But first, we showcase some of the shockingly accurate commentary from the blinded beta-testers recruited on PricePlow’s Discord, and allow you to sign up for our MuscleTech alerts, because we have a ton more information on its way:

What is enfinity? Introducing Paraxanthine…

Everyone knows caffeine, the world’s most popular drug / dietary supplement ingredient that provides energy and wakefulness through its inhibition of phosphodiesterase and adenosine.[1]

The three metabolites of caffeine

Caffeine Metabolites

Caffeine has three major metabolites, and one of them (paraxanthine) does the heavy lifting. The other two have very long half-lives, which could be interfering with your quality of energy! Image courtesy Wikimedia

What most people don’t know is that the caffeine molecule itself isn’t doing most of that work. Once metabolized in the liver, caffeine leads to three metabolites, in order of prominence:

  1. Paraxanthine
  2. Theobromine
  3. Theophylline

Paraxanthine: doing the heavy lifting

It turns out that much of the heavy lifting of caffeine’s effects are done by the first of the group — paraxanthine — which has been shown to be a potent force both in terms of lipolysis (fat burning)[2] and adenosine antagonism.[3] It also provides much of the actual dopamine upregulation we feel when taking caffeine.[4]

Paraxanthine has stronger binding potencies for adenosine and leads to greater motor-activating effects than caffeine itself, and can increase processing speed, improve response time, and promote sustained attention while reducing errors.[5,6] We’re even seeing better muscle mass, strength, and endurance in mice with it![7] This (and more) will be covered in content as we dive deep into the new research.

Theophylline and theobromine – drivers of caffeine’s side effects?

It also turns out that when you take caffeine, the other two metabolites may actually be driving some of the side effects, if for no other reason that their half-lives are incredibly long — theobromine’s average half life is 6.2 hours and theophylline’s is 7.2 hours in humans.[8]

So when you take that 4pm dose of caffeine in your pre-workout supplement to hit the gym after work, your body has basically only cleared half of the theophylline and theobromine by 11pm. This can lead to awful sleep, as many of us have experienced after taking a stiff pre-workout too late.

Paraxanthine, on the other hand, has a shorter average half-life at 3.1 hours, leading to caffeine’s general half-life of 4.1 hours.[8] The above factors combined have led paraxanthine to demonstrate less toxicity in preclinical studies compared to caffeine itself — yet with greater wakefulness than drugs like modafinil![9]

Paraxanthine Reaction Time

Paraxanthine consumption leads to significantly reduced reaction time[6]

Does caffeine wreck you? You may be a slow metabolizer

Many of our followers need to keep caffeine doses low and only take them early in the day — if they take it at all. Research has shown that caffeine’s metabolism varies quite a bit across genetic and ethnic distributions.[10,11] Put very generally, there are slow, medium, and fast caffeine metabolizers, and those on the slower end of the spectrum don’t do very well with the compound.

Paraxanthine: a better experience for more users

enfinity Science

A brief intro to the science of paraxanthine / enfinity. We’ll cover far more data in the future!

What users are anecdotally finding thus far is that taking only paraxanthine itself leads to a far smoother and more consistent experience. Its shorter half-life works much better for slower metabolizers, especially without having to deal with the consequences of theobromine and theophylline hanging around for too long.

Even more interesting is that longer-term paraxanthine (those who are using it for a month or more), have consistently begun to say that caffeine feels “dirty” if they return to it.

Meanwhile, researchers have made statements such as, “As for paraxanthine it is also supposedly to be fairly harmless for humans”,[12] referencing research from the late 1980s![13] Newer safety and toxicity research also confirms this and more, showing a higher LD50 and no evidence of genotoxicity.[14]

enfinity: paraxanthine from a tested and trusted source

It’s time that paraxanthine was finally released to the world for those who are tired of caffeine and some of its consequences. Four individuals who are no strangers to the dietary supplement industry (nor to PricePlow Nation), Shawn Wells, Kylin Liao, Dr. Ralf Jaeger, and Dr. Martin Purpura have joined forces to form Ingenious Ingredients, shortened to ING2.

Developed and Tested at NNB Nutrition

Many readers will recognize Shawn Wells and Kylin Liao as leaders of NNB Nutrition, an industry-leading novel ingredient manufacturer where Shawn is the Chief Science Officer and Kylin is CEO. NNB is manufacturing, testing, and purifying this ingredient on behalf of ING2, who are the IP holders and also currently the distributors of enfinity.

NNB Nutrition

NNB Nutrition is a highly-trusted, innovative ingredient development company with an elite team of over 100 scientists from over 10 countries. Two of their executive officers, Shawn Wells and Kylin Liao, are part of the ING2 team. NNB will be manufacturing and purifying enfinity.

These veterans bring their elite manufacturing and biochemical expertise to the industry, providing an alternative energy source to caffeine. For many, this is the ingredient that you’ve been looking for. And MuscleTech will be the first to bring it to you in dietary supplements.

You can learn more in Episode #072 of the PricePlow Podcast, where we brough MuscleTech’s Raza Bashir, VP of Scientific Affairs and Product Innovation, to teach us more about paraxanthine!

We’ll be covering enfinity and paraxanthine in far greater detail in the future, but for now, let’s get into the three products MuscleTech will be releasing:

The MuscleTech iQ Series: Smarter Supplements

Over the years, MuscleTech has created countless energy supplements, and have brought some incredibly unique compounds and extracts to the industry. They’ve heard their customer base loud and clear: athletes want something new, something legally compliant, and something clean.

enfinity is just that ingredient – and MuscleTech is branding this the iQ Series, calling the smarter way to supplement. Let’s quickly look at the three supplements that will kick it off:

  • EuphoriQ Pre-Workout

    The aptly-named EuphoriQ pre-workout supplement is a caffeine-free — but certainly not stimulant-free — pre-workout experience with 300 milligrams of enfinity in a one-scoop serving. Offerint “Ultra-clean pre-workout energy”, MuscleTech is pairing this potent dose of paraxanthine with clinically-backed servings of L-citrulline (4 grams), beta-alanine(3.2 grams), and betaine anhydrous (2.5 grams).

    MuscleTech EuphoriQ Pre-Workout Supplement

    To make it even more interesting, they’re also utilizing the nootropic nitric oxide enhancement supplement nooLVL from Nutrition21. We often see nooLVL in gaming supplements, but thanks to its ability to improve blood flow, it’s a great crossover into cognitive-boosting pre-workout supplements.

    As you can see from the label attached, there’s more than that, including alpha-GPC as a choline source and L-tyrosine to keep the neurotransmitters flowing.

    If you’re tired of jittery pre-workouts, then get ready for the clean, smooth energy and cognitive enhancement of enfinity combined with nooLVL. This will be a can’t-miss supplement:

  • Burn iQ Smart Thermo (powder)

    MuscleTech isn’t one to leave dieters at bay, however. While there may be some lipolytic benefits from the paraxanthine in EuphoriQ, they really amp up the fat burning effects in Burn iQ Smart Thermo, a weight loss drink that’s optimized for energy, cognition, and shredding – keeping you level while dieting.

    MuscleTech Burn iQ Smart Thermo

    Each scoop has 150 milligrams of enfinity, and it relies on a large dose of L-Carnitine L-Tartrate to help mobilize the fat to the mitochondria for bruning.

    We’ll also see many popular and potent weight loss ingredients like coleus extract (standardized for forskolin), grains of paradise extract, phenylcapsaicin, and black pepper extract to amplify it all. If you haven’t noticed, there’s going to be some spice here, but you’ll be very pleased with the Sweet Heat flavor.

    A green coffee bean extract brings healthy chlorogenic acids to the powder, but don’t worry — it’s been decaffeinated — so you’ll get to experience paraxanthine alone as the only stimulant.

  • Burn iQ Thermo (capsules)

    Finally, the company that brought Hydroxycut to the world isn’t going to leave the fat burner capsule category hanging! If you prefer not to drink your energy and want to take a few capsules before hitting the gym, Burn iQ provides a smarter way to get shredded.

    MuscleTech Burn iQ Smart Thermo Capsules

    Here, we have 100 milligrams of enfinity per capsule, so you can take anywhere from 1-3 to get your desired effects. Many of the other ingredients discussed above are the same, we’ll only have to sacrifice on the L-Carnitine dosage, since you can’t fit all that powder into just a few capsules.

So no matter what your preference is – pills or powder, pre-workout or weight loss — MuscleTech has a smarter way for you to get clean energy from enfinity.

More to come!

This article is only the beginning. We’ll be covering each supplement in-depth, taste the flavors, discuss the research, and have PricePlow Podcast episodes to get into the weeds of this launch.

As an update later in 2023, we posted a new article titled Paraxanthine: Caffeine’s Major Metabolite for Laser-Targeted Energy, which discusses the ingredient in greater detail and introduces its new global distributor, TSI Group.

For years we’ve been waiting for The Next Big Thing, and it’s here from MuscleTech. Get ready to get smart – the iQ Series is set to revolutionize the energy industry.
