SuperSize Reviews: “SuperSize doesn’t quit…”

I recently began using Athletic Xtreme SuperSize, and this thing is the Energizer bunny of pre-worout supplements. I’ve tried tons of different pre-workout supplements, and I assumed that this would be the same as all the others. But hey, trying one more pre-workout supplement couldn’t hurt, even if it was the same as all the rest. I was expecting a sugar and caffeine filled concoction, something that would probably just make me jittery, but after trying SuperSize, I was pleasantly surprise. I started out with the recommended one scoop, to assess my tolerance, and boy oh boy was that one hell of a workout! The pump was great, my endurance had improved, but there was something that set SuperSize apart from all the other pre-workout supplements; the mental focus.

The mental focus that you get from AX SuperSize is unreal; I have never experienced one like it. Most pre-workout supplements make me less focused due to the excessive amounts of stimulants, but not SuperSize. I was looking forward to each set, not wanting to rest at all. My focus and drive was insane, and I was even throwing in extra sets at the end of each exercise because I felt that I could just keep on going. The value of this product is great, too. While I have taken two scoops at once, I find that one scoop is more than enough to notice an improvement in vascularity, massive pumps, and the unbeatable mental focus and determination. If you’re looking to step your workouts up a notch, try out SuperSize by AX, as it is by far the best pre-workout supplement I have ever tried.

SuperSize Reviews: “SuperSize”

I had read a few SuperSize Reviews before, but I wasn’t entirely convinced. You always hear the same kind of things about pre-workout supplements, but I decided to give AX SuperSIze a shot. The reviews of SuperSize had been very positive, so I figured it couldn’t hurt to give it a shot, especially since it’s a great deal. I was doing two training sessions each day for an MMA fight that I had coming up, and I was constantly exhausted. With SuperSize I had the extra endurance and energy that I felt that I needed to keep pushing it to the limit in the gym. Both with MMA training and strength and conditioning training I noticed huge improvements in my endurance, allowing me to complete more repetitions in sets, and keep the intensity higher for longer. I was setting PR’s left right and center, and this was while I was training twice a day, which is extremely impressive given how fatigued I should have been. I also noticed a decrease in body fat and an increase in lean mass after having used SuperSize for a little over a month. I highly recommend SuperSize if you want to step your workouts up a notch.

“SuperSize Testimonials are the Real Deal”

I have been testing AX SuperSize for a little over a month now, and I am blown away. I’ve tried all of the popular nitric oxide products; Jack3d, 1MR, Super Pump… you name it, I’ve tried it. They’re all the same; products which rely way too heavily on dangerous stimulants, and result in a huge crash and other side effects like being jittery. SuperSize, to my surprise, is nothing like that. SuperSize reviews all mentioned that they didn’t experience the jitteriness that many pre-workout supplements bring along, and it’s true. I didn’t experience any jitteriness, only an intense pump, insane mental focus, and increased drive and determination.

I wanted every rep more than I wanted the one before, and I wasn’t going to quit before I got those reps. Hell, I even threw in extra sets because I just felt like I had to keep going. It was like SuperSize had taken control of me and turned me into a lifting machine. Set after set after set of high intensity, heavy weight lifting, and I was hardly fatiguing at all. I wouldn’t be able to keep up this intensity during a workout without Athletic Xtreme’s SuperSize, and I’m so glad I have been able to test the product. The first day I noticed some pretty intense pumps, and I’m not sure why, but after a few days I noticed that I was experiencing even more intense pumps.

Don’t ask me why, because I don’t know, but I absolutely loved the increase in the pumps. So without a doubt, SuperSize is going to be my new pre-workout supplement for quite some time now.

Add your reviews below!

One of the most important things with Athletic Xtreme SuperSize is the ingredients. As a pre-workout supplement, Athletic Xtreme SuperSize sets itself apart from other pre-workout supplements due to the fact that it does not contain dangerous stimulants such as 1,3-dimethylamylamine. The SuperSize ingredients compose the proprietary blend, 2700mg of which is in each scoop. So let’s get down to business and talk about the specific SuperSize ingredients that make it such a great nitric oxide supplement.

SuperSize Ingredients

Let’s go over each of the main ingredients so that we can get a feel for what’s in SuperSize. It’s up to you to make sure that you can handle every ingredient. Typically, none of these are banned by any drug-testing organizations, but it’s important to talk to your governing body about this product if you are under drug testing.

Ingredient Dosages… Some UNCONFIRMED Guesswork

Note that besides the creatine, we don’t know how much of any ingredient is inside. However, a bit of math can leave us with some solid guesswork:

The proprietary complex is 2.7g, and creatine is at 1.5g. This leaves us with 1.2g left for the rest.

Guessing how much caffeine would be most important, because that’d allow us to determine the amount of leucine nitrate, more or less. I’d venture a guess that there’s 75mg of caffeine per scoop (AX reps have basically confirmed this too).

So basically, each scoop should have roughly 1-1.1g of leucine nitrate. That’s a solid dose if you’re taking 1.5-3 scoops of this stuff, and leaves no surprise why the pumps are great, considering other arginine nitrate-based products’ dosages!

What’s funny is that 2 scoops of SuperSize is then about 150mg – “small time” compared to the competition – but it’s still getting everyone completely zoned in! How’s that? It’s all about the extra focus ingredients that we discuss in detail below, which make it a great product to use when you’re getting too deep into a stim-cycle.

So let’s have at it..

HPLC Pure Creatine Monohydrate (1.5g)

As one of the most heavily studied supplements out there, creatine monohydrate has been proven time and time again to be a safe and effective supplement for gaining strength and building muscle. While creatine is a fairly standard ingredient in pre-workout supplements these days, many products still contain inferior, or untested forms of creatine than creatine monohydrate.

This is a nitrate product (leucine nitrate is the next ingredient), but it does NOT contain creatine nitrate. Why? Because creatine nitrate is unproven. Pure Creatine Monohydrate, in its proper form as represented by SuperSize here, is the MOST studied, MOST reliable, and UNBEATABLE version of creatine. I love new stuff just as much as anyone, but when it comes to creatine, you stick with decades of success.

As a result, any other product with other variations will give you less than satisfactory results. AX SuperSize contains 1.5mg of creatine monohydrate per scoop, and if you take three scoops (most people should be fine at 1.5-2 scoops though), you will be consuming 4.5mg of creatine; a great amount of creatine. With three scoops you shouldn’t need to supplement any additional creatine, as 4.5 mg is approximately the recommended dose of creatine daily.

If you use less SuperSize, then you can always add AX’s German Creatine to your post-workout protein shake (we like MTS Machine Whey).

Leucine Nitrate

Leucine Nitrate is the ingredient that gives you the tremendous pumps that are so strongly desired by every pre-workout supplement buff out there. The Nitrate is what gives you the massive pumps during your workout, and the pumps from Athletic Xtreme SuperSize are some of the strongest and longest lasting pumps out there.

Leucine is an extremely important ingredient, as it is an essential amino acid that promotes muscle growth an endurance. When the nitrate goes to work for your extreme pump, leucine does its job providing extraordinary muscle growth, recovery, and endurance; three things that every nitric oxide supplement should provide in addition to the pump, but often don’t.

But leucine needs to be delivered to the muscles, and to do that, they’re carried by blood. Increased blood flow helps — but how do we increase it? Well, that’s where the nitrate comes in, which indirectly helps you release more nitric oxide (NO). Nitric oxide is a gas that is a vasodilator, meaning it widens your veins for more bloodflow, giving you that awesome pump in so many nitric oxide supplements.

But why stop there? With Leucine-Nitrate, you get increased bloodflow WITH the benefit of delivering the #1 most important amino acid for anabolic muscle growth, L-Leucine, alongside it! And not only that, but this compound is highly water soluble, so it’s not broken down when you mix SuperSize up.

This truly is an incredible “double-whammy” ingredient that isn’t found in many products – and when you try it, you’ll agree.

Please note that while AX is advertising “8 hour pumps”, you’ll really feel the huge pumps while working out and 2-3 hours after. It will then begin to subside a little bit. However, if you do anything that uses your muscles within 8 hours, it will STILL be alive in your body, bringing the pump back! In fact, one in-house AX tester said that he got a JAW pump because he was bulking and ate a ton that day! Imagine that!

These ingredients which cause the pump with AX SuperSize are much different than the pump obtained from other supplements that have standard AAKG (arginine alphaketogluterate), like Jack3d. The pump is just as intense, if not more intense, and you aren’t consuming some of the dangerous stimulants that your body gets used to. If you are tired of taking a nitric oxide product like Jack3d, or if your body just doesn’t react to it anymore, then AX SuperSize is the product for you.

The patent holder of leucine nitrate is strict about how much gets put into products. They don’t want someone to just add a little dash so that a supplement manufacturer can claim it’s in there. They are forcing a strong enough dosage to get you a REAL pump, and SuperSize sticks to that contract!

Disodium ATP

Disodium ATP is a unique ingredient that is not found in many pre-workout supplements other than Athletic Xtreme SuperSize. As you may or may not know, ATP is the primary source of energy for our body’s cells. Exogenous ATP has been shown to increase ATP levels within the body, thus making more energy available for our cells. Creatine is popular because it vastly increases ATP levels and seriously works.

The problem is that supplementing ATP simply doesn’t work – it’s not bioavailable and your digestive system will destroy it before it gets through.

Not the case, however, with Disodium ATP (disodium salt of adenosine 5′-triphosphate (ATP)), as discovered by world-renowned scientific researcher, Dr. Eliezer Rapaport. Disodium ATP stays LIVE in your system and in SuperSize since it’s water-soluble, and doesn’t need to be enteric coated, or specially treated. Dr. Rapaport also noted that it synergistically increases bloodflow when combined with arginine – something SuperSize has as well!

Anyway, Disodium ATP increases your performance, endurance, and recovery by allowing the body to have more energy readily available to be used. The usage of Disodium ATP allows your body to have much more energy without the use of dangerous supplements such as 1,3-dimethylamylamine, ephedrine, or other stimulants.

Just think of it like this: ATP = ENERGY and ENDURANCE, but we can’t just take ATP. However, we CAN successfully take Disodium ATP, and mixing with arginine amplifies both of their uses.

Final Note – Disodium ATP is actually a prescription drug in France, named ATEPADENE. It’s that good for bloodflow and energy bursts.

Caffeine

Nearly everyone is familiar with the benefits of caffeine, whether it’s from your morning coffee or from pre-workout supplements. Even if you don’t go out of your way to consume caffeine, you probably consume some throughout your day to day life from the foods that you eat. If you don’t consume much, or any, caffeine at the moment, then you should start slowly with AX SuperSize. Caffeine can work wonders for mental focus, fat burning, and increased intensity of workouts.

Caffeine is what is known as a thermogenic product, and this essentially means that it heats up your body. This aids in fat loss, as your body is burning more calories as a result of the increase in heat.

PEA Break! We need to discuss PEA Before Continuing…

Haplophyllum Tuberculatum Extract [Whole Plant] Standardized For P-Phenethylbenzamide

Whoa there – Let’s break this one down into words we can understand. First off, Haplophyllum Tuberculatum is a small, yellow, flowering plant with long stems. It actually originally grows a lot in the middle east, mainly Saudi Arabia.

Athletic Xtreme is taking this whole plant, and doing whatever it is they need to do (most likely grinding it down, dissolving it in a water-based solution, and separating the good stuff out), and then extracting P-Phenethylbenzamide from it. So P-Phenethylbenzamide is the ingredient in question here.[1]

P-Phenethylbenzamide is a different type of PEA, as mentioned above. The benzamide part of this compound protects it from MAO. You have two types of MAO, and both of them oxidize, or break down, stuff that we don’t want to be broken down when we’re trying to get amped up for a workout!

• MAO-A breaks down Serotonin, melatonin, norepinephrine, and epinephrine.
• MAO-B breaks down Phenethylamine and benzylamine.

So basically, adding this seems like a bit of a “trick” that AX is doing to get your body to accept more PEA, mimicking a high dosage – meaning more focus and even a bit of euphoria!

[1] As a sidenote, some believe that should actually be named N-phenethylbenzamide, where the benzamide part is attached to Nitrogen (N). We don’t think this is a mistake, as Athletic Xtreme has their own method of extract. Either way, that’s not a big deal – just focus on how this gets more PEA into your brain

Theobromine

Also known as xantheose, theobromine is another ingredient that comes from chocolate (specifically the cacao plant). It is in the same family of compounds as caffeine, and has similar effects, but they are a bit weaker.

We are interested in this ingredient for a few reasons: First and foremost, it’s a vasodilator. Like the nitrates, it will open your blood vessels up, giving you a better pump, better bloodflow, and better nutrient delivery of the other ingredients.

Second, this helps in fat loss, which is a great “side effect” of this ingredient. This is done via reducing excess water weight, as well as decreasing appetite. It’s even been linked to having aphrodisiac effects!

However, it’s the energy and increased bloodflow that we’re interested in here. More theobromine and less caffeine is a welcome thing here – this is another reason why SuperSize is great to take when you’re trying to ease off of the insane, 300mg-per-serving pre workout supplements.

Neuropeptide Alpha [Peptide Bonded Tyrosine and PEA (Tyrosine-Phenethylamine Peptide)]

This is definitely one of those “last but not least” moments. Neuropeptide Alpha is why we think everyone is REALLY getting into the zone but not getting stimmed out with SuperSize. This has to do with the PEA information discussed below.

So, like we said, PEA works like a stimulant and helps release adrenaline and dopamine, but is normally quickly destroyed by MAO if taken orally, so very little gets to the brain.

So here’s the trick: Tyrosine can get into the brain easier than PEA. It passes the blood-brain barrier via the Large Neutral Amino Acid Transporter channel. So what Athletic Xtreme did was to bond PEA to Tyrosine, and allow the PEA to ride “piggyback” through this channel!!

So now that we can get PEA into the channel, we can get the stimulant and focus effects of it and MAO can’t cause a chemical reaction to break it down as easily. So to translate, Athletic Xtreme is smart and invented a cool way to make you smarter with this.

When you try SuperSize, you’re going to think to yourself, “There’s a little something extra going on” – definitely more than just some caffeine. I am fully convinced that this feeling is due to the amazing effects of NeuroPeptide Alpha.

SuperSize Ingredients Summary

So as you can see, there are a number of ingredients found in AX SuperSize, some unique to it, and some found in other pre-workout supplements. It is the unique combination of these ingredients that sets SuperSize apart from other pre-workout supplements, however. So by now your question of what is in SuperSize should be answered. You should hopefully understand the different ingredients and how they work together to ensure that you achieve extraordinary mental focus, pump, and performance.

The ingredients in SuperSize really shine when your body has become used to other nitric oxide supplements, as it does not contain the same stimulants as many supplements such as Jack3d contain. The unique ingredient combination also ensures that you can take SuperSize for months without having the nitric oxide having a diminished effect.

If you’re looking to buy SuperSize, then, if you’re anything like me, you’ll want to get the best deal on it possible. Retail stores often charge insane prices for supplements; sometimes their prices are twice what you can find the product for online. That’s not to mention that if you shop online you can even get free shipping sometimes, and you often don’t need to pay sales tax either. It’s logical when you think about it; retail stores need to pay for the product, pay to have it shipped, pay to have their store, and then charge sales tax. All of these things add up to an increased price of SuperSize when you buy SuperSize in stores. If you want to find get SuperSize for cheap, then online is the way to go.

Just like every supplement out there, there are potential side effects that accompany Athletic Xtreme SuperSize. While there are relatively few side effects with AX SuperSize, there are still some things that you need to watch out for, so precautions must be taken to ensure that you stay safe.

This is not an end-all, be-all document, and comments are welcome below. As always, consult your doctor before beginning any supplement regime, especially if on prescription drugs (we cannot answer questions about them). This site is not run by Athletic Xtreme, nor are we affiliated with them in any manner, and we are not responsible for the contents of their product.

For your safety, the instructions MUST be followed in order to minimize any SuperSize side effects. The side effects of SuperSize are as follows, and while they are relatively rare, you must be cautious and aware of the potential side effects. The side effects of SuperSize can be more common for individuals who are taking medications or have pre-existing medical conditions.

Potential SuperSize Side Effects Explained

Let’s take a look by examining the potential dangers of the main ingredients.

Creatine Side Effects

While it is a highly effective supplement, there are no known side effects of creatine monohydrate, the form of creatine found in AX SuperSize. There are often rumors floating around about creatine being bad for your kidneys, but this is untrue, and has not been backed up by any studies. In fact, all studies have shown that there are no negative side effects of creatine monohydrate when supplemented.

Caffeine Side Effects

Caffeine is one of the ingredients of SuperSize that does have potentially negative side effects. It is typically fine for people when used properly, but if taken in excessive doses then some side effects may occur. If you are already consuming a large amount of caffeine without SuperSize, you should want to cut back on your caffeine intake, and also start with a low amount of SuperSize. SuperSize should not be mixed with other stimulants whatsoever, so if you are taking any other pre-workout supplements that are stimulant based, you should stop taking those immediately, as the amount of caffeine from the two supplements could potentially cause negative side effects. Negative side effects of caffeine include anxiety, insomnia, heart palpitations, muscle twitches, irritability, and more.

Caffeine is also a diuretic to those who aren’t used to it, so be sure to consume more fluids than you normally would, as excessive caffeine intake can lead to dehydration. Staying properly hydrated is especially important for active individuals, so you should make sure to hydrate especially well while consuming AX SuperSize. The side effects of AX SuperSize can for the most part be avoided, as exemplified with the caffeine side effects.

Side Effects of Leucine Nitrate

Leucine Nitrate is one of the most important ingredients in SuperSize, but as a result there are some potential side effects. These instructions must be followed in order to ensure that you remain healthy while taking AX SuperSize. Nitrates are known to lower blood pressure, so the appropriate dose must be taken to avoid lowering your blood pressure excessively. Before taking any supplement, consult your doctor to see if it is safe for you, regardless of whether or not you are taking any other medication.

With that being said, do not mix Athletic Xtreme SuperSize with medications for erectile dysfunction. We cannot answer questions regarding any specific prescription drugs, but erectile dysfunction medications should not be taken with this supplement, and you should consult your doctor with regards to any other medications.

With non-stimulant, but arginine-nitrate based pre-workout supplements, such as Yok3d or NO3 Chrome, a maximum of three caps of Yok3d or NO3 Chrome, with one scoop of SuperSize should be taken. This is due to the aforementioned issue of lowering blood pressure by too much.

Other Ingredients and Possible Dangers

The other ingredients in SuperSize are all naturally occurring compounds, sometimes bonded so that they remain stable inside of your digestive system – this means more gets to your nervous system and less gets excreted or converted to waste – and THAT means less potential sides!

Side Effects of SuperSize Overview

So as you can see, there are a few potential side effects of SuperSize, but they can be avoided with relative ease for the most part. You should consult your doctor before starting to use this supplement, and extra care should be taken if you are taking any prescription or over the counter medications.

If you do notice any negative side effects, stop taking SuperSize immediately, and consult your doctor about the side effects. Some individuals should take extra care and be especially careful before taking SuperSize.

The side effects of SuperSize can be especially dangerous for individuals who have certain medical conditions. These medical conditions include, but are not limited to cardiac arrhythmia, stroke, seizure disorder, psychiatric disease, diabetes, high or low blood pressure, heart, liver, kidney, or thyroid disease, difficulty urinating due to prostate enlargement, or if you are taking any medications, especially erectile dysfunction medications or a Monoamine Oxidase Inhibitor (MAOI). Provided all the precautions are followed, there are very few side effects that cannot be avoided. The SuperSize side effects are rare but they still occur, so as such you should be careful with taking the supplement.
