Extreme Nutrition LEAN-R Fat Burner Review // Is It The Strongest?

Extreme Nutrition LEAN-R Fat Burner Review // Is It The Strongest?

my bite2First Look:

LEAN-R is definitely going for that edgy, raw, dark and mental gym look.

It seems to add weight to the claim that this is strongest legal fat burner available.

However, it is up against some pretty arduous competition.

I can see that is has 9 ingredients present and no proprietary blend which already wipes the floor with much of the shit that is on the market, so let’s look more closely.


N-Methyl TyramineNot an ingredient that should be used in dietary supplements designed to promote weight loss. It may result in an increase in perceived energy by promoting appetite and the digestion and absorption of nutrients while inhibiting the breakdown to fats to energy.


Cocoa Bean Extract – Studies show that in conjunction with a controlled diet, cocoa bean extract may play a role in body weight management.


Bitter Orange (Citrus Aurantium) – At present, Citrus aurantium may be the best thermogenic substitute for ephedra.

However, more studies are needed to establish this definitively.

Bitter orange is possibly unsafe when taken as a supplement for a medical purpose such as weight loss.

Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.

There are reports that bitter orange can trigger headaches, including migraine and cluster headaches, in some people.

Bitter orange can cause sensitivity to the sun. Wear sunblock outside, especially if you are light-skinned.



Garcinia Cambogia – Supposedly helps people lose weight, however, trials have been unsubstantiated or at least unimpressive.


Caffeine – This can assist with endurance, tested athletes saw an edge from caffeine in scientific studies. In some trials, the stimulant boosted athletes’ speed. In others, it helped them last longer before they spent all their energy.

Caffeine also raises the metabolism which means you burn more calories. Some studies show that it can curb soreness after exercise, too. This means you could get back to your training sooner and training means more calories burnt. This is present in all 3 of our Top Fat Burners.


Paullinia Cupana (AKA Guarana) – Studies note that 75mg guarana (9mg caffeine) was able to enhance cognitive scores related to memory and reaction time with a subsequent dose-response study noting that 75mg was more effective than higher (150-300mg) and lower (37.5mg) doses.


Tyrosine – Tyrosine is taken for depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), the inability to stay awake (narcolepsy), and improving alertness following sleep deprivation. It is also used for stress, Parkinson’s disease, Alzheimer’s disease, chronic fatigue syndrome(CFS).


Octopamine – Banned by the WADA. The claims of fat burning may not actually be true and are untested in humans. Risky.


BioPerineThe extract of piperine, called BioPerine®  in the patented form, has been clinically tested in the United States. BioPerine®  significantly enhances the bioavailability of various supplement nutrients through increased absorption.



There is a 3 pills twice per day recommended dose.

We prefer 4 pills spread across the day to evenly spread the nutrients out and prevent massive peaks and troughs.

4 pills are the doses of our benchmark products. There’s a useful 4228mg daily serving here.

Benefits & Effects:

There are 2 conclusive and proven fat burning ingredients present out of 9 ingredients.

They are Caffeine and Citrus Aurantium.

Both are effective, however, one of which is also potentially dangerous.

At least the Bioperine assists with the absorption of the ingredients…good and bad. Which could be a double edged sword.


The potentially dangerous Citrus Aurantium is a bit of a shocker, Too many supplements include this. While it is great for the manufacturer’s to say their product is “strongest” that is no good if you’re going to have a heart attack.

It is like a drug dealer telling you how great their MDMA is, great but you may also die, face down, in a washroom, covered in sick.

The bottle also states it is WADA safe. However, Octapamine is banned by the WADA and isn’t proven to be effective anyway.

Guararna is also hugely overdosed to be suitably effective, it should be dosed at 75mg not over 1200mg! Lack of research here.

Garcinia and Cocoa are both unsubstantiated in trials.

Then we have N-Methyl Tyramine which is a bit of a problem ingredient. It almost makes you think that you are expending more energy that you are by increasing appetite and digestion. It doesn’t though.


There’s far too much risk involved here with this fat burner.

Not only is one ingredient, while potentially a good fat burner, it is also potentially good at putting you in hospital.

Plus there’s also a WADA banned ingredient as well.

Then a completely over dosed ingredient rendering it ineffective not withstanding a collection of other ingredients bar one which is actually scientifically proven to work.

That is a lot of negatives and nearly no positives.

Caffeine saves the day in this one plus a large overall daily dose.
