About The Product

Lightspeed is a fat burner supplement made by Limitless Pharma. It costs $49.99 for 30 serving containers, with a serving size of 1 per day - unusually for a fat burner, it comes in powder form.

We prefer fat burners that provide 3-4 servings per day; this keeps your body topped up with the ingredients it needs to increase your fat burning potential (to shred more body fat).

Who are Limitless Pharma? 

Limitless Pharma are a Canadian supplements company. However, apart from that, there wasnt much more information available on their website.

It seems like a fairly new company, so lets see whether Lightspeed can help them gain a good reputation.

Lightspeed Ingredients Explained

Lightspeed contains 14 ingredients - which is a lot for a fat burner. As weve mentioned, not alot is known about the company behind this fat burner, so hopefully Lightspeed can get into our good books.

Anyway, this is probably the most important section of this review; you can see whether a supplement will be safe or effective by analyzing its ingredient list. Were glad that Limitless Pharma hasnt hidden any ingredients in proprietary blends, so well give them credit for this.

Not good serving size 

We believe the best fat burners contain 5-7 ingredients thatre proven to work, without causing you side effects - in this case, less is more.

That takes us to our next point: Lightspeed contains numerous ingredients thatre shown to cause side effects… 

Risk of numerous side effects 

There are 4 ingredients thatre commonly reported to cause side effects in Lightspeed. In fact, we try to avoid supplements containing them, so itll be useful for you to read our analysis of this fat burners ingredients.

Remember that there are ingredients that are effective without causing side effects - so theres no excuse for a company to add those that can cause you potential harm.

Is this a fat burner or pre-workout?

After taking a quick look at Lightspeeds ingredient list, were confused whether Limitless Pharma have designed this to be a pre-workout or a fat burner.

We assumed it was a fat burner, as it says Hardcore Fat Burner on the packaging (as you can see from the image above) - but there are numerous ingredients that are more commonly seen in pre-workouts, such as L-Tyrosine.

Anyway, well take a deeper look at each ingredient inside Lightspeed - to show you how effective this fat burner really is.


Heres Everything You Need To Know:


L-Tyrosine is a brain-booster ingredient thats shown to improve your cognition - for this reason, its one of our favorite ingredients in nootropic supplements.

However, it doesnt promote fat loss or offer any benefit youd buy a fat burner for - meaning its an ineffective ingredient in Lightspeed.

Not a good start by Limitless Pharma here.


This is our favorite stimulant in both fat burners and pre-workout supplements; Caffeine is the safest stimulant on the market, and everyone knows it boosts your energy levels (which is helpful when youre cutting calories and body fat).

Its consumed on a daily basis in products such as tea & coffee - and its only when you drink too much, that you experience side effects such as jitters. Well, this is the same for fat burners - if it contains too much Caffeine, then it can also cause jitters and energy crashes.

If Lightspeed had 3-4 servings per day, the Caffeine dosage would be split up - which would ensure your safety from side effects. However, as it comes with 1 serving per day, youll be consuming the full 200mg in 1 dosage (increasing your risk of jitters and energy crashes).

For this reason, its important to always check the Caffeine dosage in supplements.


DMAA is a stimulant thats similar in structure to Ephedrine, and is used in pre-workout supplements and fat burners for this reason. However, as of 2017, DMAA has been banned from supplements by the FDA in the USA.

Theyve released an official statement: Ingestion of DMAA can elevate blood pressure and lead to cardiovascular problems ranging from shortness of breath and tightening in the chest, to heart attack. 

For this reason, we avoid any supplement containing DMAA - and we recommend you to do the same.

White Willow Extract

This is taken from the bark of the White Willow tree, and is used as medicine to treat headaches, muscle pain, muscular cramps and arthritis.

As a result, it might reduce cramping in the gym - but its not shown to deliver any benefits to improve your gym sessions (meaning its ineffective in Lightspeed fat burner).

Grains of Paradise 

This is a type of chilli pepper thats found in West Africa; this is a good thing, as chilli peppers are thermogenics (meaning they raise your body temperature, which raises your metabolism - encouraging your body to burn more fat as fuel).

However, there hasnt been enough research on Grains of Paradise for it to be reliable or safe. For this reason, we always stick to what we know - Cayenne Pepper has proven to be both safe and effective, so theres no need to fix something thats not broken.


Matcha Green Tea Powder 

This is a great fat burning ingredient thats proven to work - its finely grounded green tea, which has shown to promote fat loss in countless studies.

In fact, its been used for centuries in East Asia, as its known for benefitting almost every organ in your body too. Theres nothing bad about Green Tea Extract (or Matcha Green Tea Powder), and its proven to work.


Synephrine is one of the ingredients we stay away from - basically, its been reported to cause numerous side effects, as weve had bad experiences after consuming Synephrine too.

For this reason, its been banned in the UK - we recommend you to avoid any supplement thats been banned in a certain country, as these ingredients dont just get banned for no reason.


Higenamine is a plant thats believed to treat asthma - but studies have shown that it doesnt promote fat loss. As a result, its an ineffective ingredient inside Lightspeed fat burner.


This compound is believed to promote fat loss, but studies have shown that its not very effective; meaning its useless in fat burner supplements.

Hordenine is actually a common ingredient in both fat burners and pre-workouts - so its worth knowing that it doesnt work.

Cayenne Pepper Extract

As we mentioned with Grains of Paradise, Cayenne Pepper Extract raises your metabolism - allowing your body to use body fat as fuel.

Its proven to work, and youve probably experienced sweating after eating spicy food. For this reason, its one of our favorite ingredients in any fat burner supplement.

Grapefruit Extract 

This is nothing special; its simply extracted from Grapefruit, a fairly popular fruit used in salads and desserts. It hasnt shown to promote fat loss, so its not very useful in Lightspeed either.

Huperzine A 

Huperzine A is on our blacklist of ingredients to avoid in fat burners. Simply put, its been reported to cause numerous side effects when consumed in supplements - and weve even had bad experiences with Huperzine A ourselves.

This is why we try to avoid fat burners containing this ingredient.

Black Pepper Extract 

This isnt a key ingredient in any supplement, but its a good bonus ingredient to have; Black Pepper Extract has proven to boost the absorption rate of supplements its consumed with.


Yohimbe is also an ingredient on our blacklist of ingredients to avoid; simply put, its been banned in numerous countries after causing harmful side effects. Weve also tested supplements containing Yohimbe and experienced unwanted side effects too.

For this reason, we recommend you to avoid any fat burners with Yohimbe inside.

Side Effects

There are 4 ingredients that can cause side effects in Limitless Pharmas Lightspeed - DMAA, Synephrine, Huperzine A, and Yohimbe (with 3 of these being banned in numerous countries as a result).

Weve tested supplements that contain Syneprhine, Huperzine A and Yohimbe ourselves; we suffered from side effects which well list below, which is why we recommend you to avoid them too.

As the FDA strongly recommend that you avoid DMAA, weve never tried supplements containing it before - but weve seen many reports about it causing side effects. Remember that theres fat burners that contain ingredients thatre both safe and effective (so theres no need to take supplements that can make you feel like sh*t).

Heres the potential side effects from taking Lightspeed: 

  • Rapid Heartbeat (DMAA)
  • High Blood Pressure (DMAA, Yohimbe)
  • Nausea (Synephrine, Huperzine A, Yohimbe)
  • Anxiety (Synephrine, Huperzine A, Yohimbe)
  • Upset Stomach (Yohimbe)

Lightspeed Ingredients Explained

At the start of the review, we wondered whether Lightspeed could help gain Limitless Pharma a good reputation. Well, the answer is: No, it wont.

This company has shown its done some research in terms of ingredients - adding some key ingredients such as Green Tea Extract (Matcha), Cayenne Pepper Extract & Caffeine. However, theyve also displayed their inexperience in the industry, by adding potentially harmful ingredients (DMAA, Huperzine A, Yohimbe & Synephrine).

Not only that, Limitless Pharma have shown their inexperience by not adding an ineffective serving size in Lightspeed; simply put, a fat burner needs 3-4 servings per day, so your body is always topped up with key fat burning ingredients for it to work. Lightspeed only offers 1 daily serving, which will only stay in your system for a couple of hours (making it ineffective).

Limitless Pharma Lightspeed Review

Bottom Line

Ultimately, we cant recommend that you try Lightspeed - weve reviewed much better fat burners that havent caused any side effects.

Not only that, for almost same price as Lightspeed ($49.99), you can get our top rated fat burner supplement at the moment.
