Welcome to the most comprehensive G Fuel review on the world wide web!
Fed up of the endless marketing jargon and sales pitches which dominate brand websites, or don’t feel like you can trust product reviews on sites which are quite clearly on the payroll? That’s where we come in!
This Gamma Labs G Fuel pre-workout review gives you all the information you need to know about this product in order to make a decision as to whether it’s right for you! From how much it costs and what flavors are available to a detailed breakdown of the ingredients and their dosages based on the latest scientific research.
Let’s face it, the world of nutritional supplements is a murky one, with loose regulations allowing manufacturers to get away with way too much. Pre-workout, whilst potentially beneficial, epitomise this laissez faire culture and must therefore be treated with caution, with the requisite research being completed before purchase.
For every pre-workout product on the market which will actually be of benefit to your training and help you make the extra gains it promises, there are dozens more which simply won’t. Our job is to point you in the direction of the ones that will help and steer you clear of those which offer you nothing but pricey piss!
What is G Fuel used for?
G Fuel is not actually marketed as a pre-workout supplement at all, but rather has a healthy energy drink alternative! According to the website, the products have a wide range of users from professional athletes in the NFL, and amateur bodybuilders, to online gamers , and everyone else in between.
It is endorsed by one of the most famous streamer and international video gaming superstar Dr Disrespect.
Gamma Labs appear to be very inclusive and have attempted to produce an energy drink with a wide range of consumers in mind!
Sugar and gluten free, and packed full of antioxidants, G Fuel contains pretty much the same amount of caffeine as a large cup of coffee and, according to Gamma Labs, should be treated in a similar way!
With only 25 kcals per serving and just 5g of carbs, this could be great option for those who are looking for a convenient energy boosting drink without some of the drawbacks associated with most products in this marketplace!
Is G Fuel FDA approved?
In a word… No. But neither are any other nutritional supplements or pre-workout products on the market as this sector is not subject to such regulations. As a result, as a consumer, you must be extra careful when choosing products in this area as they can sometimes contain harmful ingredients!
G Fuel ingredients
Gamma Labs Gaming Fuel is made up of not one but THREE PROPRIETARY BLENDS!
For those of you out there who are a little unsure as to what exactly a proprietary blend is, then read carefully. It is a mix of ingredients included in supplement products where each individual ingredient is listed but not necessarily their individual servings, with a total blend weight disclosed instead.
Now this can be particularly unhelpful when you’re trying to monitor exactly what and how much of everything you are consuming, especially given that many of the ingredients we are talking about must be dosed at optimal levels in order to be effective.
Whatever supplement manufacturers try to tell you about why it is they make use of proprietary blends, there is only ever one reason, and that’s to hide underdosed ingredients from YOU!
In the case of G Fuel, the tell tale signs are all there, 3 ingredient mixes, all with names containing the word complex. In fact, the only ingredient included which does have its dose disclosed is caffeine!
Let’s take a closer look at which ingredients actually feature and where possible compare doses to what the latest scientific research is telling us!
Energy Complex (1.85g)
The first of the three proprietary blends contains taurine, citrulline malate, caffeine and carnitine.
Caffeine (150 mg)
We’ve started with caffeine as it’s the only ingredient present in this blend which has its precise serving disclosed, so we can at least compare it to what the latest scientific research says.
Caffeine is without doubt the most common stimulant ingredient found in pre-workout products and energy drinks such as G Fuel, and for good reason, as there are a wealth of studies which support its efficacy for exercise performance.
Not only does it help users to achieve an optimal physical and mental state prior to and during exercise, but it can also boost the amount of fat your body is capable of burning throughout a workout. WINNING!
Most research suggests that doses as low as 100 mg are effective whilst it can be consumed safely at levels as high as 400 mg per day! That means the 150 mg contained in every serving of G Fuel can be likened to what you might get in a large cup of coffee. You will almost certainly feel the effects, unless of course you are a hardened stimulant veteran, in which case, this rather low key energy drink may not be what you’re looking for!
Undoubtedly one of the most exciting nutritional supplement ingredients on the market today, citrulline is increasingly finding its way into pre-workout products. By increasing your blood levels of an amino acid called arginine, citrulline supplementation helps to increase your production of nitric oxide. This in turn leads to greater vasodilation, which means improved circulation and increased blood flow to working muscles.
This not only allows for a delay in fatigue during intense sessions but also gives you a great muscle pump!
Most of the scientific research suggests that a serving of 6-8g around 30 minutes before your session is sufficient to bring about the above benefits. Whilst we have no idea exactly how much citrulline is included in this first blend, it is impossible for there to be a meaningful dose as the total blend weighs just 1.85g.
Disappointing to say the least!
Taurine and carnitine
We have grouped these two ingredients together because there is limited research to support either of their uses within exercise performance.
Taurine has been purported to help improve endurance, but research has indicated that supplementing with 1-6g before exercise does not improve overall performance. Given that there is probably a very small serving in this 1.85g blend, we find it incredibly unlikely that there would be enough to generate whatever benefits there MAY be anyway!
There is some evidence to suggest that carnitine has the potential to help increase fat burn during training but studies are limited at best, and as a result any kind of optimum dosage is not yet known!
Focus Complex (1g)
The second of this products three proprietary blends contains tyrosine and ATP. There is some limited research to suggest that tyrosine can improve cognitive performance as well as boost energy levels due to its relationship with hormones such as adrenaline and noradrenaline.
These studies are limited, however, and as such there is no confirmed optimum dosage even if the evidence proves to be unequivocal!
This complex also contains something called ATP (adenosine triphosphate), which is the foundation molecule within the human body which provides the energy you need to achieve any kind of meaningful and conscious physical output!
You would, therefore, be forgiven for thinking that an ATP supplement would be incredibly useful when it comes to boosting your exercise performance. Unfortunately you’d be wrong! ATP is simply not bioavailable when consumed orally and therefore its inclusion in this G Fuel energy drink is largely a waste of time, irrespective of dosage!
Antioxidant complex (163.5 mg)
The third and final proprietary blend is simply a complex of multiple fruit powders with supposed ‘antioxidant’ properties. These ingredients may indeed be good for your overall health but they are unlikely to be of much benefit to your exercise performance!
Does G Fuel give you energy?
The caffeine content in this Gamma Labs G Fuel product is similar to that of a large cup of coffee so it will undoubtedly offer an energy boost of some description. Whilst there are a few other ingredients included which have the potential to increase energy levels, such as tyrosine and citrulline malate, none of them are dosed anywhere near highly enough to be of benefit in this department!
Gamma Labs G Fuel pre-workout side effects
There is probably just one ingredient included in this G Fuel product which has the potential to cause some minor side effects and that is caffeine. In large quantities it can cause diarrhea, vomiting, the jitters and even anxiety. But given the relatively mediocre 150 mg dose present in G Fuel, these symptoms are incredibly unlikely, unless of course you have a particularly low tolerance level to caffeine!
Pros and cons of Gaming Fuel by Gamma Labs
How much does Gaming Fuel cost?
There are a whopping 26 flavor options of Gamma Labs Gaming Fuel which means even the fussiest of consumers out there will be able to find not just one but multiple tastes to their liking! This number of flavors is by far and away the best offering we have ever seen in the pre-workout/ supplement market!
At $35.99 on the official Gamma Labs website, G Fuel comes in at a pretty reasonable price of $0.90 per serving. Given that all you get for your money is 150 mg of caffeine, however, then this cost is still relatively expensive.
Summary: G Fuel pre-workout review conclusion
All in all this has been an incredibly disappointing G Fuel review! Whilst it is perhaps unfair to compare this product to others within the pre-workout market, simply because it is marketed as an energy drink, it still contains many of the ingredients you would expect to see in a pre-workout product and therefore there is the same responsibility to provide these ingredients in the correct doses. And boy does it fail to do this on any level!
The availability of so many different flavor options is certainly a major positive, but it is in no way enough to warrant a $0.90 per serving price tag for what is essentially just a caffeine supplement!
Our advice, if you’re after a low key energy drink which works out cheaper than something like Red Bull and is probably better for your overall health than most energy drink competitors, then G Fuel could be for you.
If you take your training seriously and are looking for that extra edge to help you make the most gains possible, then we would suggest looking elsewhere for your pre-workout needs!
