What to Look for in a Thermogenic Pre Workout Fat Burner

Balanced Formula

Probably one of the most important considerations when buying pre-workout supplements is that they should have a balanced formula. Avoid pre-workout supplements that only focus on a single aspect, like energy, at the cost of performance and pumps.

Effective Ingredients

Thermogenic pre-workout powder and regular pre-workout energy supplements may have a lot of similarities in ingredients, but they are fundamentally different. 

For instance, pre-workout supplements are designed to boost metabolism and may contain ingredients to counter the effects of reduced appetite. Thermogenic also often contains less caffeine than regular pre-workouts.

On the other hand, pre-workout energy supplements promote focus during exercise and may contain ingredients, such as nitric oxide, to promote nutrient delivery and protein synthesis.

The main ingredients you’ll often find in thermogenic pre-workouts include caffeine (increase fat burning and metabolism), green tea extract, CLA or conjugated linoleic acid, L-carnitine (for metabolism and energy production), and capsicum/cayenne.


The best thermogenic pre-workouts feature a fully-disclosed label and are also not underdosed for the safety of people taking it. 

Value vs. Cost

It is important to invest in high-quality thermogenic pre-workout powder to keep up with the latest body conditioning techniques. Cheaper fat burners are often packed with fillers and are mass-produced so they provide little nutritional value.

But high prices do not always mean the fat burners are made of quality ingredients. So, always read the label and weigh value over cost.

Final Verdict: Which One Should You Buy?

As you can see in the list above, there are great thermogenic pre-workout supplements available in the market today. But for our top pick for the best overall fat-burning pre-workout, it would be the PhenQ Fat Burner.

The PhenQ is hands down one of the best pre-workouts you can buy at its price point and has a solid ingredient profile. What makes it stand out from other fat burners in this list is that it has a unique blend of ingredients and contains the trademarked formula called α-Lacys Reset®.

This ingredient alone fires up the body’s thermogenesis and accelerates metabolism, so you can burn more calories quickly than taking other thermogenic pre-workout products. Other ingredients you’ll find in this product are a blend of capsicum, niacin (vitamin B3), caffeine, and piperine that help you slim down.

But if you prefer fat-burning pre-workouts that are not so potent, then go for Cellucor C4 Ripped. It has lower caffeine content than other fat-burning pre-workouts we listed. Its formula is ideal for ages 18 and up. It supports your body’s ability to burn fat while helping you train harder.

We also like that Cellucor C4 Ripped are available in incredible flavors, including Tropical Punch, Raspberry Lemonade, Icy Blue Razz, Fruit Punch, Cherry Limeade, and more!
