Lean EFX Fat Burner Review

November 8, 2021 Talib Ahmad Supplement Expert 819 Views

Thermogenic fat burners can be a great addition to a weight loss regimen in order to break through a plateau. But with so many options, knowing which would be good for you can be difficult to filter through. In this post, we’re going over a popular thermogenic fat burner Lean EFX and comparing it to other popular thermogenic like Hellfire and Black Mamba.

What Is Lean EFX:

As we mentioned, Lean EFX is a thermogenic fat burner. This means that the ingredients in Lean EFX are more oriented to promoting thermogenesis or calorie burning than other fat burner properties. However, it does feature other classic fat burner properties like promoting energy, supporting appetite suppression, and even aiding in mood/focus. † While individual experiences will vary, the most prominent customer feedback we receive about Lean EFX is about the energy and thermogenesis.

Research currently indicates that for a fat burner to be considered “good” it should do several things: (1)

Burn stored fats
Break down and mobilize the fat cells
Increase metabolic rate
Inhibit the enlargement of fat cells

Some ingredients that may promote this include stimulants like caffeine, green tea, yohimbine, and ephedra*. As well as other ingredients like carnitine, conjugated linoleic acid (CLA), chromium, chitosan, and pyruvate. (1)

The Original Lean EFX:

Like many fat burners from the early 2000’s, Lean EFX had an original formula that was revised and reformulated. In the original formula, Lean EFX Refined featured 3 matrixes for a total of 738mg of active ingredients.

These matrixes were divided into sections, the first being the Next Gen EFX™ matrix featuring:

Caffeine
Evodiae Fructus
Green Coffee Bean Extract

Following is the Thermo EFX™ matrix featuring:

L-Phenylalanine
L-Theanine

And lastly, the Neuro Therapy EFX ™ matrix featuring:

N-Acetyl Tyrosine
L-5-Hydroxytryptophan
Panax Ginseng Root

Next Gen EFX™

Caffeine & Weight Loss:

There are many published studies that indicate caffeine can be effective for weight loss and reducing body fat. In brief, these studies show caffeine’s capabilities of increasing the release of stored fat cells and promoting the calorie burning. As well as it’s properties as an energy enhancer, cognitive performance booster, and appetite suppressor. (1,2,3,4,5)

Evodiae Fructus & Weight Loss:

Evodiae Fructus is a well-known herb in traditional eastern medicine for common aliments like headaches or abdominal pain. (6) One of the major bioactive components, evodiamine, shares similar effects to capsaicin. This is due to its vanilloid receptor agonistic activities. As a result, Evodiae may aid in thermogenesis. (7)

Green Coffee Bean Extract & Weight Loss:

Similar to caffeine, Green Coffee Bean Extract has many published studies indicating it’s potential effectiveness for weight loss. Where these studies support that Green Coffee Bean Extract can promote the reduction of body fat through its anti-obesity properties. (8,9,10)

Thermo EFX™

L-Phenylalanine & Thermogenesis:

L-Phenylalanine is more often discussed in mood boosting/focus complexes rather than in thermogenesis. However, Phenylalanine is among several amino acids that promote insulin release. Where insulin sensitivity and release is related to promoting muscle protein synthesis. Increasing muscle protein synthesis and muscle anabolism (growth) improves overall metabolism. Which in turn promotes thermogenesis. (1,11,12)

L-Theanine & Thermogenesis:

Like phenylalanine, L-theanine is an amino acid, but it is a nonprotein amino acid. Recent research suggest it may be effective in promoting thermogenesis, as well as improving glucose tolerance and insulin sensitivity. (13)

Neuro Therapy EFX™

N-Acetyl Tyrosine & Cognition:

N-Acetyl L-Tyrosine may be an effective neuro-cognitive amino acid. It’s popular for improving alertness, attention, and focus. But when it comes to weight loss, Tyrosine may also be beneficial for regulating metabolism (14,15,16).

L-5-Hydroxytryptophan (5-HTP) & Cognition:

5-HTP is a precursor to serotonin. Meaning once consumed, a chemical reaction occurs to produce serotonin (17).

Panax Ginseng Root & Cognition:

Known as the root of vitality, Panax ginseng is a traditional herb that has been used in Chinese medicine for centuries. Studies suggest that ginseng could improve cognitive functions like memory, social functioning, and mood.(18)

Lean EFX 2021:

In the current formula of Lean EFX there are the same 3 matrixes, but they combine for a total of 705mg of active ingredients.

These matrixes are divided into the same sections, beginning again with the Next Gen EFX™ matrix featuring:

1,3,7-trimethlyxanthine
Cassia Nomame
Taraxacum
Green Tea Extract
Bearberry
Niacin

Next again is the Thermo EFX™ matrix featuring:

2-Aminoispheptane HCl (DMHA)
Thiamine Disulfide
Phyllanthus Emblica
Bitter Orange

And finally the Neuro Therapy EFX™ matrix

5-Hydroxytrptophan
N-Acetyl Tyrosine
Panax Ginseng

Next Gen EFX™: What’s Different?

The first change in this matrix is the increase in ingredients within the matrix. This matrix now includes 5 ingredients compared to the previous 3, which includes:

1,3,7-trimethlyxanthine (Caffeine)
Cassia Nomame
Taraxacum
Bearberry
Niacin

While there are additional ingredients in the blend, there is less milligrams in the whole blend, 375mg compared to the previous 490mg. Of these ingredients, only caffeine is shared between the formulas. Meanwhile Niacin, which was originally outside of the proprietary blends, is now within the matrix.

Cassia Nomame:

Cassia Nomame is a plant native to Africa. Its seeds are often used to make an herbal supplement. The main active components in cassia nomame may slow the breakdown of dietary fat.† Which may result in dietary fat to be excreted. For some people this could promote weight loss†. But more research is needed for this ingredient.(19)

Taraxacum:

Dandelion, or Taraxacum officinale, is a well-known and effective natural diuretic. This plant has been seen to enhance kidney activity and increase the frequency of urination. The bitter root-stock of the dandelion is used as a digestive aid to improve appetite, stimulate the production of bile, and also help reduce problems with water retention.(20)

Bearberry:

Uva ursi, also known as bearberry, is a small ground cover shrub. It has been used for diuretic and kidney strengthening purposes since the 1500s. Today, it is mostly used to treat urinary tract infections and alleviate inflammation of the urinary tract. But Bearberry may have immediate diuretic properties and may support reducing water retention and bloating.(21)

Thermo EFX™: What’s Different?

The next matrix features an entirely new blend of ingredients and increased volume of active ingredients. This includes:

2-Aminoispheptane HCl (DMHA)
Thiamine Disulfide
Phyllanthus Emblica
Bitter Orange

DMHA:

DMHA is a stimulant similar to DMAA. It’s used as a decongestant in some countries, but it’s also gaining popularity as an ingredient in dietary supplements. It can improve energy levels, improve mental clarity, and help increase physical performance. It may also help with weight loss by increasing metabolic rate. (22)

Thiamine Disulfide:

Thiamine Disulfide is a derivative of thiamine that may have a higher bioavailability and solubility than thiamine. This derivative may play a significant role in the metabolism of carbohydrates and lipids. In addition, it appears to have antioxidant properties. (23)

Phyllanthus Emblica:

Indian gooseberry (Phyllanthus emblica), also known as Amla, is primarily found in South Asia. The fruit has traditionally been used for treating a range of ailments from hair loss to preventing cancer. But more recent studies have indicated that various phytoconstituents of this extract may have significant anti-obesity potential. (24)

Bitter Orange:

Citrus extracts like Bitter Orange extract are very common in fat burners to increase thermogenesis, which means they have the potential to increase your energy expenditure.(25)

Neuro Therapy EFX™: What’s Different?

Lastly, we have the Neuro Therapy EFX™ matrix, which features the same ingredient profile as the previous version of Lean EFX but at a lower volume of active ingredients. The current formula contains 90mg of active ingredients compared to the previous versions 140mg.

How Does It Compare?

When you compare Lean EFX to the previous Lean EFX Refined, you may initially feel discouraged by the decrease in total active ingredients. However, because the new formula contains DMHA, we believe this version is stronger in terms of overall strength as a thermogenic and for long-lasting energy.

With the addition of Bitter Orange Extract, this formula’s energy complex is amped up without being too intense. So while the blend may not be suitable for new users/individuals with a low tolerance to stimulants, it’s a great option for mid-to-high tolerance stimulant users. Also worth noting that including two diuretic ingredients may be beneficial for individuals who struggle with bloating, but this means staying hydrated will be very important with Lean EFX.

Lean EFX Reviews:

Review By Stacey

“AWESOME tons of energy” Posted on 10/18/21

Review By Alexandria

“I was trying to go for something outside of Hydroxyelite, and I knew I tried LeanEFX in the past. However, it’s a wonderful thermo…sweat like crazy. But I’m use to a stronger appetite suppressant.” Posted on 1/05/21

Review By Virginia

“It works! Two months on two months off
Great product! Been using it on and off since 2018 they stopped selling it in most places but glad same day supplement carries it!” Posted on 3/10/20

Lipodrene Vs Lean EFX:

In our first comparison, we have Lipodrene with ephedra By Hi-Tech Pharmaceuticals, which is another popular thermogenic fat burner. Lipodrene’s formula contains 660mg of active ingredients total compared to the 705mg of active ingredient in Lean EFX. Of those 660mg, 6 ingredients are shared with Lean EFX.

This includes:

2-Aminoisoheptane HCl (DMHA)
Citrus Aurantium Extract
Cassia Nomame Extract
5-Methoxytryptamine HCl
L-5-Hydroxytryptophan
Caffeine

This leaves 8 ingredients from the formula that are different.

Of the remaining ingredients, 4 are popular stimulants in fat burners; like Ephedra, Senegalia Berlandieri, Synephrine HCl, Theobromine, and Yohimbine. (26,27,28,29,30,31) These ingredients may aid in promoting energy, thermogenesis, and appetite suppression for Lipodrene.

Mean while ingredients like Green Tea Extract, Naringen, and 6,7 Dihydroxybergamotin may aid in thermogenesis. (32,33,34) Finally, the Hoodia Extract may aid in promoting appetite suppression. (35)

Overall, we rank Lean EFX as a stronger thermogenic fat burner compared to Lipodrene. However, Lipodrene may have a better appetite suppression complex and may have a more potent stimulant complex.

Lipodrene Review:

“I have been taking Lipodrene for a long time and it had been my favorite fat burner! I highly recommend it!!“

Hellfire VS Lean EFX:

Next, we have Hellfire Fat Burner By Innovative Labs, one of our strongest thermogenic fat burners. Hellfire’s formula contain 535mg of active ingredients compared to Lean EFX’s 705mg. Between both fat burners, there are only 2 ingredients shared, Caffeine and DMHA.

The remaining 9 ingredients feature a combination of fat burning properties.(26,27,36,37,38,39,40,41,42)

When you compare these fat burners, Hellfire is likely to be a stronger stimulant/thermogenic fat burner compared to Lean EFX. But, Lean EFX may be a good match for appetite suppression with Hellfire, while still being a good thermogenic. Additionally, Hellfire doesn’t contain ingredient for focus/mood support. So we would rank Lean EFX higher in this category.

Hellfire Review:

“Always increases energy and curb appetite however you must get off of it for at least a week to 2 to keep up the effects after being on it for 6 weeks. Lost 50 pounds in 4 months. Great product! Haven’t found anything better yet. Always A+ customer service and shipping as all.”

Diablos ECA VS Lean EFX:

Compared to .Diablos ECA Fat Burner By Innovative Labs, there are 4 ingredients shared with the blend of 550mg ingredients. This includes:

Caffeine
2-Aminoisoheptane (DMHA)
Citrus Aurantium Extract
Green Tea Extract

Then 12 of the remaining 14 ingredients are split between common fat burning categories:(26,27,28,43,37,33,34,40,42,44,45)

Finally, the last 2 ingredients White Willow Bark Extract and Cissus Quadrangularis Extract don’t fit into common fat burner categories. White Willow Bark Extract acts similarly to aspirin. This comes into play as the “ECA” in Diablos’ name, which stands for Ephedra, Caffeine, Aspirin. An ECA stack was common and popular fat burner stack among the bodybuilding community. (46)

Cissus Quadrangularis is a herbal ingredient that is packed with antioxidants. Surprisingly, it’s more common to see this ingredient in products related to joint health. Yet, there are some studies indicating that it may be beneficial in weight loss, weight management, and prevention of metabolic syndrome. (47)

Diablos ECA and Lean EFX seem like a good match up overall, but the energy/mood boosting properties in Diablos may be more potent. However, there are more direct thermogenic ingredients in Lean EFX.

Diablos ECA Review:

“I bought this fat burner since Hellfire has been out of stock for a while, and I was pleasantly surprised by how similar this is to Hellfire. It is a little lower in the ephedra content, but this felt a lot better than the Hellfire did. I think I just found my new fat burner of choice!”

Black Mamba VS Lean EFX:

Our next popular thermogenic comparison is with .Black Mamba Fat Burner By Innovative Labs. Black Mamba features 555mg of active ingredients with 2 direct ingredient comparisons; Caffeine and DMHA.

The remaining 10 ingredients can be split into our 3 common fat burner categories.(26,27,28,37,1,11,12,33,34,48,49)

In our last comparison between Black Mamba and Lean EFX, we’d rank Black Mamba as a stronger stimulant fat burner compared to Lean EFX. But, Lean EFX as a stronger thermogenic compared to Black Mamba.

Black Mamba Review:

“Very good product. It is difficult to rate the effectiveness of a fat burner. I’m currently using this product in the final weeks of prep for a show. I will say I’m happy with the definition I have gotten. However, you must have your diet dialed in and already at fairly lean (you can see your abs) to see the true effectiveness. Hope this helps.”

Which Should You Try?

*Notice Of Delays*

Currently, there are a lot of delays with products in production, manufacturing, and importing. So unfortunately, your options for trying fat burners are limited. But that’s why we write blogs, so you can find the best option available! At Same Day Supplements, we are accepting pre-orders for fat burners affected by the delays like Hellfire, Black Mamba, and Diablos.

But if you don’t want to wait out the delays, Lean EFX is readily available to ship!

Overall, we believe that Lean EFX would be a great choice for most people. It has a good blend of thermogenic ingredients, which research indicates can be effective at helping you burn fat.†

However, If you were looking for a fat burner with a focus on stimulant/energy, products like Hellfire or Black Mamba may be better for you. As for appetite suppression, while Lean EFX has appetite suppressing properties, we expect products like Lipodrene or Black Mamba to hold the reigns. When it comes to Diablos and Lean EFX, Diablos may be better for energy, but we expect Lean EFX to be better for thermogenesis.

If you’re looking for a high-stim fat burner, rather than a thermogenic, we recommend checking out Her Ab Ignitor. Or if you thought Lean EFX was too strong for you checkout HyperCuts or Raze.
