As someone who struggled with some unwanted flabby stuff at various stages in life, I know exactly how easily you can be tempted into buying dietary supplements you see advertised online.

Unfortunately, there are so many hyped-up products out there that it can really be difficult to find something that is both effective to increase your metabolic rate and has limited side effects.

Transparent Labs has quite a long list of health and sports supplements, and I had noticed quite a lot of people at my gym using them. One that caught my attention the most is the Transparent Labs Fat Burner PhysiqueSeries.

I had my dietitian give me a review of the Transparent Labs Fat Burner ingredients, and then I tested it out with some friends to try and gather some actual results for both cutting and general weight loss.

So, let’s dive right in.

What Is Transparent Labs Fat Burner?

Transparent Labs Fat Burner PhysiqueSeries is a thermogenic fat burner supplement designed to trigger an increase in your metabolic rate. It aids fat loss, increases energy levels, improves focus, and reduces cravings.

Without going into extremely boring details of how your metabolism works, let me give you just a really quick explanation of what that means.

Basically, any excess energy you take in is stored in the form of body fat. Our research shows this results in quite a bit of fat storage, and even performance athletes can struggle with their BMI at the low end.

Burning fat is triggered when there is a net negative amount of available energy. While diet and a strict exercise regimen can help, there are ways in which you can help out a bit.

Thermogenesis is one such way, and certain ingredients like green tea extract and caffeine anhydrous can increase your core body temperature. This requires energy, which is sourced from fat.

And that’s exactly what Transparent Labs Fat Burner does. It’s provided in the form of capsules that can be taken every day.

What attracted me to Transparent Labs Fat Burner is that the packaging is really simple, and the company doesn’t embark on major celebrity endorsements and hyped-up advertising. So, my first step was to review the ingredients with my dietitian.

What Are The Ingredients?

Supplement facts of Transparent Labs Fat Burner

Transparent Labs Fat Burner contains 9 main active ingredients that were chosen based on scientifically proven results. Let's take a look at them one by one.

1. Green Tea Extract (50% EGCG)

Many people consume green tea for its detox benefits, but green tea extract will also provide a nice boost of caffeine. Green tea extract is also the main ingredient of our best nighttime burners, as we did find some studies that have shown green tea's potential in burning fat [1].

Our dieticians also said that the major antioxidant in green tea, called epigallocatechin gallate (EGCG), can help with weight management, especially when combined with regular exercise and a low-calorie diet.

2. White Willow (60mg)

This was a new one to me, but it is a type of bark extract that has been extensively studied.

Some people also use it to relieve pain, from back pain to headaches, which may help in reducing fatigue and muscle soreness.

It seems like when combined with caffeine; it can increase the effectiveness of thermogenesis even when resting [2].

And in our experience, it’s very effective for trigger some additional fat metabolism.

3. Caffeine Anhydrous (120mg)

Yes, that morning coffee to have you wake up could be helping with the process of burning fat.

One of the most common natural ingredients in fat burning supplements is caffeine, along with green tea extract.

One thing to keep in mind, though, is that the more you take in, the less effective it will become. So be careful with supplements if you’re a coffee drinker.

I also made the mistake one day of taking it after 6 pm and ended up struggling to get to sleep.

4. Synephrine HCL (25mg)

This also seems to be a bit of a newcomer to the supplements industry. Still, there is one study in particular that verified that when sourced from bitter oranges, Synephrine HCL works to increase energy levels in resistance training targeting more fat [3].

Most users have seen an increase in energy and endurance levels, which may have helped burn more fat and build muscle mass during workouts.

5. L-Theanine (120mg)

Some people may have seen L-Theanine advertised on certain teas in health food stores to help decrease stress levels [4]. However, when combined with caffeine, we found it can help to amplify the effects on fat.

Based on my clients’ experiences, this fat burner helped reduce symptoms of physical and mental stress throughout the day.

6. L-Tyrosine (150mg)

L-Tyrosine is another interesting amino acid that affects the metabolic rate, specifically during exercise and workout phases [5]. Indeed, I noticed that I was a lot more sweaty than usual during workouts, which may be due to enhanced metabolism.

7. 5-HTP (150mg)

5-HTP is a rather cryptic name but has been shown to influence serotonin levels, which are directly tied to suppressing appetite.

During two months of testing, I have noticed positive effects in terms of appetite suppression, especially when I’m on my fasting period.

There are few studies around 5-HTP, but our research has shown its positive impact on weight loss and appetite suppression.

8. Forskolin (10% Coleus Forskohlii)

This one will be particularly interesting for people who want to achieve more muscle mass definition. A 2005 study revealed positive results for obese men where a significant fat loss was noted [6].

However, the dosage in Transparent Labs Fat Burner of 250 mg per serving might not be enough to cause significant results as most studies use more than 500 mg per day.

And our test results seem to confirm this as well.

9. Cayenne Pepper (50mg)

Cayenne pepper extract is one of the ingredients to expect in fat-burning supplements. It has been extensively tested as a natural treatment option for obesity, making cayenne pepper extract a good option for anyone trying to lose weight.

Our dieticians added that the capsaicin in cayenne pepper accelerates thermogenesis to help you burn more calories than usual.

Does Transparent Labs Fat Burner Work?

Product sample for Transparent Labs and pills

Yes, Transparent Labs fat burner works. I read through several hundred online reviews and comments in forums and Facebook groups, and the overall feedback has been very positive.

People noted that it worked well in accelerating weight loss and appetite suppression. That was enough for me to try and see how it would work in a cutting phase.

So, let’s take a closer look at the specific benefits of Transparent Labs Fat Burner.

What Are The Benefits?

Three different images of people working out

The key benefits of using Transparent Labs include weight loss, appetite reduction, and increased energy levels. Let’s discuss each of them below.

1. Improved Weight Loss

So, I had planned to reduce my BMI by 4 points over the 4 weeks, and I used a body fat caliper to get the most accurate readings. The good news was that I managed to achieve my goal a full 4 days sooner than expected.

The last time I went through a cutting phase, it took the entire 4 weeks, so that was a nice surprise. Keep in mind that I did my workout as usual, and I cut on most of my carbs during this time.

2. Reduced Appetite

I often try to go through longer fasting periods to skip my breakfast and a morning snack. That will usually mean a good 5 hours in the morning where I can feel hungry and get a bit crabby.

When I took Transparent Labs Fat Burner first thing in the morning, I got until about 11 am before I started feeling the usual hunger cravings and pains. So, from the perspective of appetite suppression, it does seem to bridge a gap.

3. Energy Boost Throughout The Day

I confirmed what I saw in quite a few reviews when it comes to some extra energy. By burning more calories and fat, I did feel like my metabolism was making a good bit more energy available.

I found that I just had a bit of an edge over my normal days, both mentally and physically. It allowed me to do my workouts more efficiently while ensuring I wasn't too tired from the day's exertions.

Any Side Effects?

Side effects from the Transparent Labs Fat Burner are very uncommon. However, people with a sensitivity to caffeine can end up with increased blood pressure and heart rate while using this product.

I also received a few comments about Transparent Labs Fat Burner causing an upset stomach when taken without food. Although I didn't experience this myself, this happens quite often, so it's best to try it after breakfast.

If you have any allergies or illnesses, it's always best to check with your doctor before using this supplement.

When Should You Take Transparent Labs Fat Burner?

You should take Transparent Labs fat burner during the earlier hours of the day. Transparent Labs recommends that you take 2 capsules twice a day with food.

I wouldn’t recommend taking it later in the day, as the caffeine dose could end up affecting your sleep. Based on my experience, it's best to consider reducing your tea or coffee intake by 1 or 2 cups a day so as not to end up overstimulated.

The more caffeine you take, the less your metabolism will react, which could have the opposite effect on your fitness goals.

What Are Users Saying?

Users are saying different things about Transparent Labs Fat Burner, but here are the ones that stood out as consistent with our experience.

"I tried a bottle of this product, and it helped me lose weight a bit quicker than before, so I'm trying a longer run to see if I get closer to my long-term goals. Definitely worth a try and drink lots of water." - Rodney T.

4 Tips For Getting The Most Out Of Fat Burners

1. Start With Your Diet

If you don’t fix your diet, then there is no point in taking fat burner products.

Any fitness goal will be 70% diet and 30% exercise, so make sure to maintain a healthy and balanced eating program while using Transparent Labs Fat Burner.

2. Plan For Regular Off Cycles

The longer you take a fat burner, the more your body will become tolerant of the ingredients. That’s why it’s best to take regular breaks. I would generally say that taking one or two weeks off for every 8 weeks of supplementing with Transparent Labs Fat Burner is the best approach.

Over time, you can see what works best for you and adjust it accordingly.

3. Drink More Water Than Normal

Taking a thermogenic fat burner entails using up more water in your system.

If you’re in a particularly active phase while taking Transparent Labs Fat Burner, we found it’s best to add at least an extra pint of water a day.

It ensures you don't end up feeling too thirsty and tired for your exercise routines and fat loss efforts.

"Never overlook the importance of drinking enough water to enhance your fat-burning benefits. Water is essential for life and optimum health, and without enough of it, your energy, strength, and metabolism suffers."
- Shannon Clark, Sports Performance Scientist.

4. Plan Your Exercises The Smart Way

When you’re trying to lose fat with Transparent Labs Fat Burner, then you need to trigger sustained processes to lose weight, and that requires higher intensity levels of training.

After some trial and error, this is when I switch to lots of high-intensity interval training (HIIT), and I even throw in a regular full-body training day as well.

Here are some other popular fat burners on the market:

Transparent Labs Fat Burner Pricing

We also had a careful look at the different order options for this Transparent Labs fat burner review. The good news is that there are some options here.

For a one-time order of a bottle with 60 capsules, it costs $54.99. And in our experience, it took about four days to receive the order.

But you can also opt for a subscription option.

This comes with free shipping, and each month, you’ll receive a bottle for $49.99. That 10% saving quickly adds up over the year.

Fat Burner Alternatives

With so many fat-burning solutions on the market, deciding which product will work best can be challenging. We’ve done some legwork and compared Transparent Labs to three popular alternatives.


Our review confirms that PhenQ is one of today's most trusted and efficient weight loss products.

PhenQ sets itself apart from other fat burners, including transparent labs, because of its multi-faceted approach to weight loss with scientifically-backed ingredients.

Our test group volunteers used PhenQ for several weeks, along with our designed workout plan and diet. They reported increased energy and decreased hunger cravings and recorded noticeable weight loss.

PhenQ and Transparent Labs Fat Burner's only common ingredient is caffeine, with the same dosage.

PhenQ uses other thermogenic and appetite-suppressing ingredients like capsimax powder, nopal, and L-carnitine, as well as the α-Lacys Reset® weight loss formula to help users lose weight in five key areas.

As a fitness coach, I appreciate that PhenQ targets stored fat and new fat production, boosts energy and focus, and suppresses appetite because I tell my clients they need to hit weight loss from all sides.

A bit pricier than other fat burners, PhenQ’s website gives incentives like free bottles and shipping for purchasing a multi-month supply.


After an extensive review on LeanBean, we found that this is another vegan-friendly, all-natural fat burner, but unlike Transparent Labs, it targets women's specific weight loss needs.

It claims to increase thermogenesis and naturally suppress appetite as it sources caffeine from natural sources; however, the dose is pretty light, and after speaking to our dietitians, it leaves me questioning its efficacy.

The formula contains thermogenic ingredients like green coffee beans and turmeric to help boost your metabolism. LeanBean also includes Glucomannan and chromium for hunger control and B vitamins to reduce fatigue, which are all absent from Transparent Labs Fat Burner.

I did not like the LeanBean dosing of six pills daily, compared to just two with the Transparent Labs Fat Burner. The results of our test group show it is an effective fat burner, but many users also thought the dosing was too much.

The price of LeanBean is on point with other fat burners. Ordering from the official website will get you bulk discounts and the advantage of their 90-day, money-back guarantee.

Instant Knockout

Originally formulated to help bodybuilders and athletes reach their performance goals through a metabolic boost and increased thermogenesis, Instant Knockout Cut has become an increasingly popular fat burner among gymgoers.

Like the Transparent Labs fat burner, Instant Knockout Cut is vegan-friendly, utilizing a veggie capsule, so this was to the delight of many of our testing volunteers.

Our research confirmed that Instant Knockout uses caffeine and green tea extract to enhance metabolism at much higher doses than Transparent Labs.

I also like the addition of cayenne to further boost thermogenesis and Glucomannan for appetite suppression.

I consulted our dietitians on the L-theanine dose, and they indicated that Instant Knockout likely includes it to promote increased focus.

Instant Knockout contains a hefty dose of caffeine, with was bothersome for some users in our test group, while others didn’t mind it. I liked the significant boost of energy to power through a hard training session.

The best place to purchase Instant Knockout Cut is from the official website. I placed a multi-bottle order and received free shipping and complimentary nutrition and workout e-g
