Legion Phoenix

Caffeine is surprisingly ubiquitous in the world of weight loss supplements, and it is often a vital component of products that claim to provide a thermogenic, fat-burning effect. This is because plain old caffeine is surprisingly effective as a weight loss aid when consumed to excess, as it causes the body to produce more energy even when resting. When combined with other stimulants like synephrine or naringin, its benefits (and side effects) are even more pronounced. Given these facts, is it even possible to produce a fat-burning, weight loss supplement that doesn’t use caffeine?

Below we take an in-depth look into Legion Phoenix, to see whether this caffeine-free fat burner can deliver the promised weight loss benefits without the side effects we normally see from these kinds of products.

Legion Phoenix Pros

  • Uses no caffeine, which gives customers the ability to control their intake
  • Backed by a strong money-back guarantee that is convenient for customers
  • Appears to be well-balanced and well-formulated, with clear ingredient quantities

Legion Phoenix Cons

  • Around a quarter of customers post negative experiences

What You Need To Know About Legion Phoenix

Legion Phoenix is a fat-burning weight loss supplement that requires customers to take a hefty dosage of 5 capsules per day. It is notable for the fact that it provides a stimulant effect that is entirely free from caffeine, with the manufacturer claiming that this allows customers to control their own caffeine intake more directly through daily coffees or energy drinks. The manufacturer, Legion Athletics, appears to be uniquely open with customers about the ingredient quantities and formulations of their products in general, with each sales page packed with useful information about why certain ingredients were/weren’t selected. This policy (amongst others) seems to have brought a high degree of trust to the brand, as well as a loyal fanbase on Amazon and other discussion groups.

What Are The Side Effects Of Legion Phoenix?

Although the manufacturer repeatedly claims that this product is entirely free from side effects, around 25% of the reviews posted to Amazon are negative. These negative reviews almost always blame side effects as the reason.

The most commonly cited side effects from using this product are nausea, diarrhoea, and jitters. If customers consume too much caffeine whilst consuming the high amounts of synephrine provided by this product, it could also cause more serious side effects like high blood pressure or heart problems.

Side effects may be avoided by taking less than the recommended 5 capsules per day (at least initially), or by making an effort to monitor your daily intake of caffeine whilst using the product.

How Much Does Legion Phoenix Cost?

A one-month supply of Legion Phoenix (with 150 capsules) costs $35 (although a small 10% discount is available if customers make larger bulk purchases). This product is available to buy on the Legion Athletics website and on Amazon.

Our Verdict On Legion Phoenix

Thermogenic fat burners are a relatively weak subset of supplements at the best of times, offering only mild benefits at the expense of a host of side effects. That being said, Legion Phoenix represents one of the very best of a bad bunch.

On the official Legion Athletics website, the manufacturer makes a significant effort to explain the ingredients that went into this product, the quantities needed, and the reasons why they were included. This transparency is useful for customers, and to the company’s credit, it looks like this formulation has been optimised to ensure these capsules remain as effective as possible. Customers are told to expect roughly half a pound of weight loss per week, which is refreshingly honest (if slightly underwhelming).

However, there are drawbacks. The manufacturer repeatedly makes the claim that Phoenix does not cause side effects at all, which is provably untrue. According to the Amazon customer review section, approximately one quarter of customers discontinued their use of this product precisely due to its habit of causing nausea, jitters, diarrhoea, and headaches. The manufacturer has clearly made attempts to reduce the likelihood of side effects by removing caffeine from the mix (which essentially allows customers to decide their own intake), but the use of ingredients like synephrine is always likely to cause issues regardless. Customers should always remain aware of this.

Overall, we approve of this manufacturer’s business practices (including their exemplary money-back guarantee), and we believe that this formulation represents a fine effort to get the most out of this approach to weight loss. If you’re on the hunt for a thermogenic fat burner, remain realistic about the modest benefits, and are prepared for side effects, this product may be for you.

We recommend Legion Phoenix to our readers!

Legion Phoenix Review

Legion Phoenix is a thermogenic fat burner that claims to raise the body’s metabolic rate and curb food cravings. Unlike most other fat burners that work in the same basic way, this product contains no caffeine as the manufacturer’s research suggests that “most people prefer to get their caffeine from other sources, such as coffee or pre-workout drinks or both”. Customers choosing to use this product are instructed to consume an unusually high number of pills (five per day), although the manufacturer maintains that this is vital for consuming the active ingredients in sufficient quantities.

What Does Legion Phoenix Claim To Do?

Legion Athletics claim that this weight loss supplement works in three key ways. It first supposedly increases the metabolism, before amplifying the strength of the fat-burning chemicals already at work in the body. It also claims to increase dieters’ feeling of satiety after eating, which effectively reduces the body’s food cravings and overall appetite.

Does Legion Phoenix Work?

To Legion Athletics’ credit, this product is very well-formulated and has clearly been designed with full consideration for effectiveness and tolerability. Most of the ingredients have been included in sufficient quantities, and most have been proven to burn fat and induce weight loss. Many have also been shown to reduce hunger pangs.

Readers should remain aware that thermogenic fat burners are a relatively imperfect type of weight loss supplement, even at the best of times. The manufacturer claims that customers can expect just 0.5lbs of weight loss per week on average, and even this modest result can be upset by failing to engage in a sensible program of diet and exercise. This product may also have to be combined with caffeine in order to produce appreciable effects.

What Are The Ingredients of Legion Phoenix?

The ingredients found in Legion Phoenix are listed below. The quantities listed are correct for 5 capsules.

  • Advantra Z Citrus Aurantium Fruit Extract (6% Synephrine) 834mg: Citrus Aurantium, also known as bitter orange peel, has been proven to raise the metabolism and aid weight loss. It contains numerous stimulant compounds, including synephrine. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it. Source
  • Naringin 600mg: A compound found in grapefruits that accounts for its bitter taste, it is known to extend the amount of time that caffeine remains in the body. This would make the effects of caffeine also last longer. Research also suggests that Naringin enhances lipid (fat) metabolism in the body, which again could have positive implications for dieters. Source
  • Epigallocatechin Gallate (from Green Tea Extract) 400mg: Studies have suggested that the EGCGs found in green tea increase energy expenditure by boosting the metabolism temporarily. However, the metabolic increase caused by these catechins is limited. One study found that the use of green tea was not enough to counteract weight gain following a high calorie diet. Source
  • 5-HTP (Griffonia Simplicifolia) Seed Extract 150mg: 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood. Source
  • L-Tyrosine 150mg: An amino acid that is a building block of protein, this ingredient is found naturally in many foods including meat and dairy products. In existing trials, L-Tyrosine appears to effectively improve cognition and memory during stressful periods. The manufacturer claims that the l-tyrosine found in this product has been included simply to restore the natural levels that may be depleted due to supplementing 5-HTP (above). Source
  • Salacin (White Willow) Bark Extract 120mg: Willow bark contains salicin, which acts a painkiller, and is thought to be as effective as aspirin. There is some evidence that when taken in conjunction with kola nut and ephedra, it can cause weight loss. It does not seem to have been tested on its own for weight loss properties, although it may amplify the effects of ingredients of synephrine. Source
  • Hesperidin 100mg: This bioflavonoid may help blood vessels to function better, as well as potentially reduce inflammation. Existing research indicates that this ingredient fails to induce weight loss. Source
  • Forskolin (Coleus Forskohlii) 50mg: This plant belongs to the mint family and is thought to boost the metabolism. However, the clinical trials performed using this ingredient have shown no weight loss, even when the participants’ lean muscle mass increased and fat mass decreased. Source
  • Hordenine HCLv (N, N-dimethyl-tyramine) 25mg: Hordenine is a known compound in Bitter Orange, and is thought to act as a stimulant to increase fat burning. Source

Does Legion Phoenix Have Any Side Effects?

Side effects associated with the use of Citrus Aurantium and its extracts such as synephrine include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of Bitter Orange extract because, in their opinion, the risk of using the product is not worth the pay-off of any potential weight loss.

The effects of synephrine and other ingredients like naringen are enhanced when combined with caffeine. This product contains no caffeine in and of itself, although customers are actively encouraged to consume caffeine to intensify its effects. Customers should also remain aware that overconsumption of caffeine whilst using Legion Phoenix will likely cause jitters, sleeplessness, and other negative effects.

Although Tyrosine is tolerated generally in very high doses, it can cause some side effects including nausea, headache, fatigue, heartburn, and joint pain. Hesperidin is known to occasionally cause stomach upset, diarrhoea, and headaches. Adverse reactions to coleus forskohli can cause worrying side effects, including a stinging in the eyes, headaches, and an increased heart rate.


Not intended for use by persons under age 18. Do not exceed recommended dose. Do not consume synephrine from other sources while taking Phoenix. Consult your physician prior to use if you are pregnant or nursing, or if you are taking medication, including but not limited to MAOIs, SSRIs, or other antidepressants or antipsychotics. Individuals with a known medical condition should consult a healthcare professional before using any dietary supplement. Exert caution when using Phoenix alongside other stimulatory and neurologically acting dietary supplements.

Are There Any Customer Reviews For Legion Phoenix?

Legion Phoenix seems to enjoy generally good reviews on Amazon, with around 75% of customers reporting positive experiences. Most praise is directed to the product’s strong formulation and good customer service, and it’s notable that most happy customers appear to be satisfied in the extreme. Negative feedback almost always centres on the product’s habit of causing side effects, some of which have been serious enough to force dieters to discontinue their use of the product.

Phoenix really worked for me. I’m halfway through my second bottle and I’ve lost 16 lbs. (I do exercise and maintain a healthy diet as well) I’m one who is sensitive to a great variety of supplements in general, but I had no ill side effects from this. I like that I had the option to take it with caffeine to improve it’s efficacy, thereby giving me the ability to control the amount of caffeine. (Usually I take Phoenix and follow it with half of a generic 5 hour energy shot) It curbed my appetite and boosted my metabolism, just what I needed it to do. I would definitely recommend this product to anyone in the market for a supplement to give them a boost on their weight loss journey.

I love the comprehensive description of every ingredient in this supplement on the Legion Athletics website. Being able to learn more about what I was taking made me feel way more comfortable trying a fat burner supplement! I do appreciate that there’s no caffeine so I can manage my caffeine intake independently. I do not feel different when taking these supplements, which is a good thing… I have noticed that they seem to have increased my metabolic activity because I’ve been exercising the same amount, eating the same amount, and sleeping the same amount, but I’m way hungrier than usual. I was already pretty lean but since starting these supplements about 3 weeks ago I have noticed some quad separation as well as a little bit of ab definition, which I have never had before.

I am on my second bottle of Phoenix, and have been impressed by the amount of fat I have lost from my midsection, primarily my stomach, but also from the love handle area. I have combined it with regular weight lifting, and have seen significant increases in definition, with no appreciable side effects.

Gave me bad diarrhea. Thought it would just be for the first few days and my body would ‘get used to it’. After a week I gave up. Hard to work out or move when you cant trust your bowels.

I’ve only taken this for 2 days, however I’ve had a headache after taking it both days and it is making me feel slightly jittery. I’m assuming it’s the Synephrine.

Does Legion Phoenix Offer a Money-Back Guarantee?

Legion Athletics offer a highly generous money-back guarantee on all first-time purchases. Within 3 months of purchase, customers can contact the manufacturer to report any dissatisfaction they may have. Customers are then entitled to receive a full refund on their original purchase, all without having to go through the hassle of sending the original container back to the manufacturer (although Legion Athletics do ask that customers physically return unopened packages that might be in a re-sellable condition). As the full value of the purchase is refunded to the buyer’s credit card without the customer having to go through the expense or time needed to arrange a return, we consider this money-back guarantee to be exemplary.

Where Can I Buy Legion Phoenix?

Legion Phoenix is available to buy on the official Legion Athletics webstore and on Amazon. From both retailers, a 150-capsule pack (a one-month supply) costs $35. Customers can access a small 10% discount by purchasing Legion Athletics products in bulk on both websites.
