We know your home gym is filled with the best home gym equipment on the market, and you’re working to get stronger, faster, and better. When you need an extra boost to power through your workout, a pre-workout supplement could help.
Pre-workout formulas contain ingredients such as caffeine, beta-alanine, and citrulline malate. These ingredients can help increase energy levels, enhance concentration and focus, and delay the time to muscle fatigue—all factors that can contribute to improved exercise performance1. Many pre-workout formulas also include creatine, eliminating your need to buy and consume multiple supplements.
Choosing the right pre-workout can be overwhelming. Some have high amounts of stimulants, and others have none at all. Some brands offer a wide range of flavors, while others have more limited options. To help you make the right choice, we’ve rounded up the 15 best pre-workouts on the market based on our in-depth, multi-point testing methodology. We personally test and rate products from 1 to 5 on factors such as the following:
- Formulation: Does it have scientifically-backed ingredients and dosages?
- Third-party testing: Can we trust that the label is accurate?
- Taste: Is it drinkable, and are there multiple flavor options?
- Price per serving: Does it fall in line with the market average, or are you paying too much?
- Solubility: Does it mix well with the recommended amount of liquid?
Our staff is comprised of certified personal trainers, certified nutrition coaches, USA Weightlifting coaches, and elite-level athletes who personally tested more than 100 pre-workout supplements for various types of training—including training for the Olympics and other international weightlifting competitions.
They detailed their hands-on experiences with each product, and I used my Ph.D. in exercise physiology to assess which pre-workouts contain research-backed ingredients, are effective, and are worth your money.

What Does Pre-Workout Do?
Most pre-workouts are made and taken prior to exercise to help increase focus and energy, while also enhancing muscle-building1. We’ll break down exactly how ingredients contribute to these goals later, especially since ingredients in pre-workouts can vary. However, many pre-workouts have key ingredients such as caffeine, beta-alanine, L-citrulline, and creatine, all designed to help hype you before your workout.

Other Pre-Workouts We Tested and Researched
There are lots and lots of pre-workouts on the market. We liked plenty more than just 15, but some just didn’t make the cut.
- HugeSupplements Wrecked: While we can agree that caffeine can boost energy levels and provide focus to a workout, too much caffeine can have the opposite effect19. A two-scoop dose of Wrecked contains a combination of four different stimulants: caffeine anhydrous (250 milligrams), Di-caffeine malate (100 milligrams), Eria Jarensis extract (250 milligrams) and Theobromine (150 milligrams). Individuals who are sensitive to caffeine may experience less than desirable side effects, like rapid heart rate, and jitteriness. Not to mention, Eria Jarensis Extract (N-phenethyl dimethylamine) is a banned substance in some countries and by some sports associations. Find out more in our Wrecked Pre-Workout review.
- BPI Sports One More Rep: One More Rep is an inexpensive pre-workout with a decent dose of caffeine (300 milligrams) per serving…and that’s about it. Some of the other ingredients, like L-citrulline, are underdosed, and each serving only has 6 grams of active ingredients.
- BPN Flight Pre-Workout: Although it contains more than 300 milligrams of stimulants, BPN’s Flight only has 2 grams of L-citrulline, and the recommended dose is closer to 3 to 6.
- BPN Endopump: This is the stim-free version of BPN Flight, and while we enjoyed the taste, we don’t feel like it offered anything you can’t find in other pre-workouts. Read our BPN Endopump review for our full thoughts.
- Insane Labz Psychotic Pre-Workout: Save your money. This popular pre-workout contains a number of stimulants, but it’s comprised of proprietary blends so it’s difficult to figure out how much of each ingredients is in this pre-workout powder. Read our Psychotic Pre-Workout review for our full thoughts.
- Ryse Godzilla Pre-Workout: Ryse has gone semi-viral on TikTok, but is it worth the hype? “This is a stronger pre-workout than what I have used before. It’s the first time I really felt the strong tingles, and I have a strong tolerance to caffeine,” says Rose, a member of Kate’s weightlifting team. Our Ryse pre-workout review has our full thoughts and ratings.
- Ghost Pre-Workout: We’ve tested dozens of pre-workout powders, and somehow Ghost pre-workout made us more stimulated than those with many more stimulants. “You won’t be sitting still and relaxing,” Jacob says. “I wouldn’t say it’s too stimulating, but I definitely feel excitable after taking it.” This isn’t a good or bad thing, just something to note.
- Bucked Up Woke AF: Registered dietitian and supplements expert Bob Iafelice said he could not endorse this product because of the large number of stimulants, including some banned by the NCAA, NFL, and MLB. “Is this product worth the risk? I don’t think so,” Iafelice says in our Woke AF pre-workout review. “Other than the stimulant package, it’s a good product with significant amounts of key ingredients such as citrulline malate and beta-alanine.”
- RedCon1 Total War: This popular pre-workout supplement has a good formulation, though you can find similar products at a more affordable per-serving cost. That said, we’ve had some of the best workouts of our lives while taking this, as you can see in our Total War Pre-Workout review.
- Apollon Nutrition Hooligan: This is a pre-workout for seasoned veterans who need an extra kick in the pants in the form of 350 milligrams of caffeine and 200 milligrams of di-caffeine malate. GGR Performance Editor Anthony O’Reilly, who has a high caffeine tolerance, said he’d only take this on days he’s going for PRs or has a prolonged training session.
- Swolverine PRE: This stim-free pre-workout is on the expensive side.
How We Picked and Tested The Best Pre-Workouts
Deciding on the 19 best pre-workouts was no easy feat. We weighed the pros and cons of each product after analyzing these factors and using our GGR supplement testing methodology:
Ingredients, Formulation, and Dosages
Are important ingredients like caffeine, creatine, citrulline, citrulline malate, and beta-alanine included? Are there research-backed dosages of said ingredients to ensure you’re getting maximum potential benefits? Are there proprietary blends, where you can’t tell how much of each ingredient is used? Are there high levels of stimulants that have been shown to have detrimental effects?
Research-backed dosages:
- Caffeine: 200 milligrams
- Creatine: At least 3 grams (5 grams is the daily recommended dose per day but not many pre-workouts contain this much)
- Citrulline: 3-6 grams
- Citrulline Malate: 6-8 grams
- Beta-Alanine: 4-6 grams
Stimulants to keep an eye out for: High levels of caffeine, dendrobium, synephrine, DMAE, rauwolfia vomitora.
Flavors and Taste
This is subjective, but we base it on the views of our testers, as well as what the general consensus is in online customer reviews. We took the individual flavor and full range of flavors into consideration.
We also looked at whether unflavored options were available.
Solubility
How well does this product dissolve in the suggested amount of liquid? Are there floaties? Is it grainy? Is it super thick or super thin? Does it separate after a few minutes?
Cost and Price Per Serving
The price per serving can range from $0.80 on the low end to upwards of $2 on the high end.
Customer Reviews
What do customers think of the product? Are reviews consistent? Does the company interact with customer reviews?
Value
If a pre-workout is expensive, is it at least packed with unique ingredients that you couldn’t find in cheaper pre-workouts? If not, you might as well buy a more affordable supplement.
Transparency and Third-Party Testing
Since dietary supplements are not approved by the FDA, having an independent third-party lab verify that what’s on the label is what’s in the pre-workout is super important, especially for athletes. This is particularly important for pre-workouts, because overloading on stimulants can be dangerous.
Transparency also plays a part in this—does the company provide COAs, not use proprietary blends, and generally seem very upfront about what’s used in their pre-workout and why?
Pre-Workout Supplement Ingredients
When you’re on the search for a good pre-workout formula, make sure it contains a majority—if not all—of the common pre-workout ingredients below.
Caffeine
Caffeine is a stimulant that targets the central nervous system, helping to support increased mental alertness while reducing the perception of fatigue. Additionally, it can increase fat oxidation and spare muscle glycogen levels20. *
Creatine
Creatine is a naturally occurring substrate that aids in energy production. When taken as a dietary supplement, creatine has been shown to promote increased muscle strength, muscle size, speed, and high-intensity exercise capacity8.
Citrulline
L-Citrulline is an amino acid that helps increase the body’s production of nitric oxide. Nitric oxide supports improved blood flow via vasodilation (widening of blood vessels)11.
Sweeteners, Sugar Alcohols, and Fruit or Vegetable Extracts
Stevia extract is a commonly used, natural, zero-calorie sweetener that is recognized as safe for human consumption, according to a 2020 research study21. However, many people find that it leaves behind a bitter aftertaste.
Artificial sweeteners like sucralose and sugar alcohols like erythritol are also found in many pre-workouts. A January 2019 study22 suggests these sweeteners are safe for most people but can cause digestive issues—like bloating or gas—in some individuals.
Instead of added sweeteners, some brands use fruit and vegetable extracts for taste. These extracts also add color and may enhance exercise performance. Some research23 shows that beetroot, for example, may improve muscle force production.
Citrulline Malate
Citrulline malate is a compound that combines citrulline with malate, a substrate essential for the production of energy needed for muscle contractions. Citrulline malate has been shown to help delay muscle fatigue and increase oxygen delivery to muscles2.
Beta-alanine
Beta-alanine is a non-essential amino acid that binds with histidine to form carnosine. In your muscles, carnosine acts as a hydrogen ion buffer to help delay fatigue and improve high-intensity exercise performance4.
Branched-Chain Amino Acids (BCAAs)
Although the jury is still out on their effectiveness, most pre-workouts contain branched-chain amino acids, or BCAAs, to help delay muscle fatigue and promote muscle recovery.
Benefits of Pre-Workout
Wondering why you should consider drinking a pre-workout before your next sweat session? Some benefits include:
Promotes Increased Energy
Pre-workouts are probably best known for their ability to support increased energy and focus during workouts. Caffeine is well-known for its ability to boost energy and endurance levels during intense workouts, and nitric oxide boosters (like citrulline and beetroot extract) can promote blood flow, which may result in more oxygen and nutrients being delivered to your muscles to maximize performance.
Improves Muscle Strength
Pre-workouts can enhance strength in several ways. For one, they can provide you with more energy so that you hit your workouts harder and increase your training volume. Pre-workouts can also help you recover faster in between sessions so you’re taking less time off.
But, perhaps the most important ingredient for increasing strength is creatine. Creatine, which is present in some pre-workouts, aids in energy production during short, intense efforts and has been shown to increase strength when combined with resistance training in numerous research studies. *
RELATED: Does Pre-workout Help Build Muscle?
Supports Enhanced Cognition
Ingredients like L-theanine, Rhodiola rosea, and L-tyrosine can help you stay focused and motivated throughout your workout. Nootropics like these have also been shown to enhance memory, attention, and concentration.
Combat Fatigue
One way to boost stamina during your workouts is to combat feelings of fatigue. Caffeine has been shown to stimulate the release of endorphins, which in turn can lower one’s perception of effort and muscle pain associated with exercise. Supplementation with beta-alanine has been shown to increase intramuscular stores of carnosine. Carnosine works as an intracellular buffer to reduce the accumulation of hydrogen ions–ultimately delaying fatigue24.
What To Look For in Pre-Workout
When you’re ready to purchase a pre-workout, keep these factors in mind.
Key Ingredients
Caffeine, citrulline, beta-alanine, and creatine can help maximize your energy and strength while reducing fatigue.
Research-Backed Dosages
Make sure key ingredients are present in research-backed dosages. There are countless research studies that pinpoint the minimal dose needed to experience energy- or strength-boosting effects from ingredients like beta-alanine and creatine, but here are a few you should know before you start shopping:
Research-backed doses of pre-workout ingredients:
- Caffeine: 200 milligrams
- Creatine: At least 3 grams (5 grams is the daily recommended dose per day but not many pre-workouts contain this much)
- Citrulline: 3-6 grams
- Citrulline Malate: 6-8 grams
- Beta-Alanine: 4-6 grams
Lack of Proprietary Blends
These blends will make it difficult to know the exact dosages used. A detailed ingredient list that clearly states the dose of each ingredient will ensure you know exactly what you are consuming.
Third-Party Testing
This means that a company, not affiliated with the supplement manufacturer, evaluates the dietary supplement to ensure what is printed on the label is actually inside the product.
If you’re an athlete, it’s critical that your pre-workout is free from any banned substance. Look for the Informed Sport, NSF, or Banned Substance Control Group (BSCG) logos on the product’s packaging to ensure the product has been batch-tested.

Is Pre-Workout Dangerous?
When taken as directed, pre-workouts are generally considered safe to use for healthy individuals. If you’re taking a new pre-workout, it’s recommended that you start with half the dose to see how your body reacts and then gradually increase from there. You should never consume more than the recommended dose, especially if the product contains stimulants like caffeine.
RELATED: How Much Caffeine Is In Pre-Workout?
Who Should and Should Not Take Pre-Workout?
Healthy individuals who need an extra energy boost for their workouts should be able to take pre-workout supplements without any issues. However, some populations, like pregnant people and adolescents, should avoid them altogether.
Additionally, people with certain health conditions should also stay away from pre-workouts. These include diabetes, anxiety, high blood pressure, insomnia, or heart conditions. Individuals who are sensitive to caffeine or have insomnia may also wish to avoid pre-workout altogether or choose a stim-free option.
Always check with your doctor before taking a new supplement.
RELATED: Is Pre-Workout Necessary?
When Should I Take Pre-Workout?
The name pretty much gives it away—pre-workouts should be taken before your training session, with most people downing their supplement 20-30 minutes before they intend to start seriously training. The key phrase there is “seriously” training because you don’t want the caffeine to hit while you’re stretching or warming up and wear off before you even hit the weights.
RELATED: The Best Ashwagandha Supplements
If you’re someone who works out in the afternoons or evenings, you should know that caffeine can sometimes stay in your system several hours after you take it. That means if you down a pre-workout even at 1 p.m., the caffeine can cause disruptions in your sleep cycle or make it hard for you to fall asleep in the first place. Consider using one of the best stim-free pre-workouts or moving your workout to earlier in the day.

Is C4 a good pre-workout?
C4 is manufactured by Cellucor, a well-known and established company in the supplement space, and is one of the most popular pre-workouts on the market. It’s affordable and no-frills, but still contains important ingredients like caffeine and beta-alanine. We recommend it on our list of best pre-workouts because of these attributes.

Does pre-workout really help?
If a pre-workout has research-backed doses of ingredients proven to increase strength, focus, or energy then yes, it can add a boost to your pre-workouts. It won’t be the be-all-end-all solution for all your training needs, but it absolutely helps.
What is the best thing to drink pre-workout?
The best thing to drink before a pre-workout is a supplement that has an effective dose of caffeine (around 200 mg), L-citrulline (3-6 g), beta-alanine (4-6 g), and other ingredients tied to increased strength, energy, and cognition. If you’re working out at night or don’t like caffeine, there are plenty of stim-free options available.
