Earlier this winter, Giant Sports allowed us to be the first to publish the amount of caffeine in their original Dexamine fat burner. Each capsule contains 175mg, which put it as the yohimbe-free alternative in the “high energy” section of our Best Fat Burner buyer’s guide.
But for many customers, 175mg just isn’t enough. If that’s you, then you’ll be happy to hear about Giant’s latest thermogenic, Dexamine Black.
Put simply, this is going to be the “crack in a can” product that stim-tolerant individuals have been craving. Yet there’s still no yohimbe, which will please those who get anxious from it.

The Dexamine Black Ingredients
Dexamine Black has a 100% open formula, so you know almost exactly what you’re getting, as the image shows to the right.
In each capsule:
Caffeine Anhydrous is the de facto ingredient that serves as the basis for nearly all fat burners on the market and Dexamine Black is not exception. What is of note, is how much caffeine they’ve managed to pack in a single capsule, 250mg! If you’re looking for a heavy dose of energy, this is it (especially if taking 2 caps twice daily)!
We’ll save the sciency talk for our next ingredient, which is what sets Dexamine Black apart from nearly all other fat burners on the market, save one. But it’s worth re-iterating caffeine has been shown to increase the rate of fatty acid oxidation. This leads to an increase in lipolysis but isn’t the complete answer for fat loss. If it was, everyone that chugs coffee for a living would be at 5% body fat.
Caffeine also boosts metabolism, increases alertness, delays fatigue, and improves mood.
The obvious issue is the dose. If you are sensitive to stimulants, you really don’t have much option here. You either take 250mg at once, or you don’t buy it… unless you feel like emptying capsules and using a scale to weigh the powder.
Even for stim-junkies, make sure to only start with 1 capsule and it’s definitely best to avoid any other forms of caffeine throughout the day.
N-phenethyldimethylamine HCl (125mg)
Here is the key ingredient to Dexamine Black that separates it from just about all other fat burners available. Any relevant research on this metabolite of PEA (phenylethylamine) is nearly impossible to find, so we went to the source to get some more information on this unique ingredient.
After reaching out to Giant Sports, they shared a little insight into this ingredient. What they’ve intimated to us is that it functions similarly to PEA but is more lipophilic, which means it crosses the blood-brain barrier much easier.
Phenylethylamine causes a powerful, albeit short, release of catecholamines (adrenaline, noradrenaline, dopamine) which improve mood and well-being. PEA’s big drawback is that it is effective but very quick-acting, with effects lasting only around 15-20 minutes.
N-phenethyldimethylamine’s enhanced absorbability means it’s taken up easier by the body and its effects will have a more prolonged effect. So, you won’t only be amped up from the nice hit of caffeine, you’ll be feeling like a million bucks with the release of all these “feel good” chemicals coursing through your brain!
Word is, if you can handle two capsules of Dexamine Black at one time (note the 500mg caffeine blast), this is the ingredient that’s going to have you feeling on another level. Just make sure you can easily handle one capsule before doing that – we still haven’t worked up to that level.
Giant Sports assures us that this new ingredient is FDA compliant, and shouldn’t be going anywhere. However, it is expensive, so seeing it in higher doses will be tough.
Update: Since writing this article, we’ve done a LOT more research on this ingredient, which is also labeled as “Eria Jarensis Extract”. You can read the updates on our post titled Eria Jarensis Extract / N-phenethyl dimethylamine: The Next Big Thing?
Grape Fruit (Citrus paradisi) (dried skin) extract (80mg)
Grapefruits have garnered attention in recent years as being beneficial for people with diabetes and for it effects on lowering blood pressure. It has even sparked an entire diet based around its purported effectiveness in losing weight, aptly titled, “The Grapefruit Diet.”
However, a systematic review of the studies conducted on grapefruit supplementation or usage being a viable means of inducing weight loss found it to be rather ineffective. So, while you may experience some improvements in health markers like insulin or blood pressure, you won’t really be seeing any additional weight loss from this extract.
Green Tea (Camellia sinensis) (whole leaf) extract (30mg)
An extract from the camellia sinensis plant, green tea extracts have gained prominence over the last decade for their numerous benefits related to antioxidant content, heart health, blood pressure regulation and a whole host of other perks.
Perhaps its most notable attribute lately is its ability to aid weight loss. When paired with caffeine, green tea extracts have been shown to increase fat oxidation and thermogenesis while lowering body weight.[6,7,8]
White Peony Tea (Camellia sinensis) (shoots and leaves) extract (25mg)
White teas, just like green teas, are derived from the same Camellia sinensis family of plants as our previous ingredient. They also share many of the same health promoting properties and polyphenols that are attributed their black and green brethren.
What separates white tea from the green and black varieties is that it has the highest concentration of antioxidants, and while it does contain similar polyphenols as that of green tea, the specific ratio of those are different between the two types of tea.
Giant Sports’ other stimulant-based products have this ingredient inside, and it definitely provides a bit of a different feel to it. Whether you’ll be able to tell when dealing with the top two ingredients, though, is up to you.
Chinese Wolfberry (Lycium barbarum) (whole fruit) extract (25mg)
You may not have heard of wolfberry before, but you undoubtedly have heard of the other name this fruit goes by…GOJI! Ancient Chinese medicine has long used this to battle diabetes and a host of other health-related conditions.
Clinical studies have shown wolfberry to be particularly effective in raising metabolism and reducing waist circumference. Additionally, a recent meta-analysis of Lycium barbarum found that the extract elicited significant improvements in neurological and psychological performance. On top of that, the test group also had vast improvements in overall mood and well-being.
Fat loss and a mood boost, wolfberry is a two headed dragon!
Bitter Orange (Citrus aurantium) (whole fruit) extract (25mg)
Citrus aurantium (bitter orange) has a track record as a proven, and safe, substitute for the now forbidden ephedra.[13,14] It’s also sometimes referred to as synephrine, and has a very similar structure to ephedra.
Synephrine acts on the Beta 2 and Beta 3 receptors in your body.[15,16] This stimulates the release of triglycerides, thereby enabling your body to burn fat as a source of energy.
The one issue is that we don’t know what specifically they’re standardizing for. As an example, we can be pretty certain that the bitter orange is standardized for synephrine content, but we don’t know for certain.
Take 1-2 capsules per day. Do not consume more than 2 capsules in any 24 hour period. Be sure to take with 16-20 ounces of Water!
Please use smart discretion with this product. It’s clear that it’s for stimulant lovers with a high tolerance, not casual users.
It’s in the tea..
While the caffeine is what’s going to gain a lot of attention – nearly nobody has fit this much caffeine into one capsule – it’s actually the tea extracts that are most likely to put stimulant-lovers on cloud 9. We’ve postulated it before, such as in our Best Pre Workout Supplement page, there’s something awesome going on with Giant Sports’ tea extracts.
Most likely the white peony tea is where this formula wins the hearts over.
Once again, notably missing is any form of yohimbe, including yohimbine HCl or rauwolscine. Giant Sports simply doesn’t like this ingredient, and many users who get anxious from it will agree. This is going to easily be the most powerful yohimbe-free supplement on the market.
This is obviously not for everyone
Clearly, this product is not for those of you who are sensitive to stimulants. It might not even be for average users.
But with an open label, we’re all for this. You know what you’re getting here – there are no hidden surprises, and the value will be quite high. This can potentially be made to last two months, if taking just one capsule per day. But we all know that if you’re taking this product, you’ll probably use it in a month.
Our suggestion would be, “If you’re unsure that you’re ready for this, you probably aren’t.”
Admittedly, nobody here has taken two capsules at once. But we’ve done one, and short of finding taking that’s now banned (such as DMAA or AMP Citrate), you won’t find a better feel from just one capsule of anything. The feel is there and you can have fun with a bottle of this for quite a while.
The question is, can you handle the dose?
And if you’re taking over 500mg caffeine per day, it may also be due time to consider a serious stimulant break for a month.
But regardless, we’ve thoroughly enjoyed taking one cap on special occasions when we’re not in the mood to take a pre workout or other forms of stimulants. This isn’t the kind of fat burner you mess around with too much… so serious contestants only, please.
But if the original Dexamine (which will remain for sale on the market, and hopefully have its label opened up as well) isn’t enough for you, then it might be time time you graduate to Dexamine Black.
