I’ve been using Swolverine Pre for the past month and while it’s not the cheapest pre-workout on the market, it comes with several high-quality, clinically dosed ingredients that kept me focused and performing well through 1.5+ hour workouts. It really out-performed when it came to increasing strength and pump, but did not provide high energy (due to being caffeine-free).

  • Swolverine is on the more expensive end at $2.12 per serving. After analyzing over 50 pre-workouts, the average cost per serving is $1.61. However, most stim-free pre-workouts cost more. For example, Legion Pulse (another popular stim-free product) costs $2.25 per serving.
  • Swolverine uses clinical doses of beta-alanine (3.2g), taurine (1.2g), and betaine (2.5g). It comes close to clinical dosing with L-Carnitine (1.5 out of 2g), and citrulline malate (5g out of 8g).
  • Swolverine is a great option for people who want to increase endurance and mental focus WITHOUT caffeine (e.g. people working out in the evening or those who consume lots of coffee or energy drinks in their day).

What Is Swolverine?

Swolverine stimulant-free pre-workout

Swolverine is a stimulant-free pre-workout that offers ingredients to support endurance, mental focus, strength, and energy. 

They use a blend of performance-based ingredients, like Citrulline Malate and Beta-Alanine along with nutrient-dense superfoods like Coconut Water and Pomegranate. 

Swolverine uses clinical dosing in their product, meaning that the quantities of ingredients found in the product match what clinical research has shown to be an effective dose. 

Swolverine uses clinical dosing in their product

They don’t use any proprietary blends, which means you can clearly see the exact amount of each ingredient found in this product (transparency like this is key when choosing a pre-workout). 

Under the product description on Swolverine’s website, they state that the product contains 2g of L-Carnitine (which would be the clinical dose), but the label on the product shows only 1.5g. 

If you consume foods rich in L-Carnitine, like lean meats, poultry, eggs, legumes, nuts, seeds, or soy then it is likely that you can get very close 2g clinical dose of L-Carnitine to experience its full effects, but I did find this a bit misleading overall. 

For enhancing athletic performance, it’s recommended to consume between 6000 mg and 8000 mg of Citrulline Malate approximately an hour before exercise. The only place I feel like this product falls short is stopping at 5000mg of Citrulline Malate as opposed to going to the clinical dose of 6000-8000mg. 

Swolverine Pre is made in the USA, is gluten-free, vegan, non-GMO, and is a woman owned company. 

Claims vs Reality: How I Felt After Taking Swolverine Pre? 

How I felt after taking swolverine pre? 

Overall, I really enjoyed taking Swolverine Pre. It was the first stim-free pre-workout I had tried in a while, and I really appreciated having a product that I could use for my evening workouts

This product is definitely a good option for fueling longer duration workouts. I used it in the mornings a couple of times where I start my workout approximately 15 minutes after waking up and my workouts only last 45 minutes. 

When I did this, I found that I didn’t start feeling the beta-alanine tingles until about 30 minutes after ingestion, when my workout was nearly half done. I was still feeling the effects of the beta-alanine and pump ingredients for an extra 45 minutes or so after my workout was finished. 

All in all, I feel like this product starts working about 30 minutes after ingestion, and lasts for 60-90 minutes afterwards. 

I also felt like I sweat a lot more than normal when using this pre-workout, so my favourite way to use it was before my longer training runs or HIIT sessions. 

The only big negative that stands out to me in regards to this product is that it claims “Energy, Endurance, Strength, Muscle”. 

Based on the ingredients and my personal experience, I feel like it hits three out of four of those. 

I agree that Swolverine can improve strength, support building muscle, and maximizing endurance. 

Swolverine can improve strength, support building muscle, and maximizing endurance

I don’t necessarily agree that Swolverine increases energy, at least not in a traditional sense. The brand themselves even stated in a response to a customer review that “it is not designed, formulated, or intended to give you a get up and go, or energy like some other pre workouts”

The one last thing I will touch on is the taste. 

Swolverine Pre is only available in Mango Lemonade, and when I mixed it with the recommended 8oz of water, I found it incredibly strong and sour tasting. 

I like sour flavors, so this wasn’t necessarily off putting for me. However, trying to drink it first thing in the morning made the taste seem especially strong and it was difficult to finish it some days.

Read more about all of the ingredients in Pre-Workout and what they do

Citrulline Malate

Citrulline Malate is a 2:1 ratio of L-Citrulline to Malic Acid. This blend is often used in pre workouts because it is believed that the combination increases the absorption and effectiveness of L-citrulline.

It functions as a Nitric Oxide (NO) enhancer, which can help improve blood flow to the muscles and heart. What this means for you is that you can notice improved strength and muscular endurance and may experience a longer time to fatigue

The clinically effective dose of Citrulline Malate is 6000mg to 8000mg daily, taken approximately 1 hour before exercise. Swolverine only contains 5000mg, falling just shy of clinical dosing. 

Beta-Alanine

Beta-Alanine is an amino acid that plays a role in lowering the acidity levels in muscles, thereby delaying muscle fatigue. 

What you will notice is an increase in muscular endurance, meaning you can exercise at higher intensities for a longer duration, before muscle fatigue sets in. 

A common side effect of beta-alanine supplementation is a tingling sensation, called paresthesia

It is a harmless side effect, and is tolerated differently. Some people like the sensation, because that helps them know that their pre-workout is “kicking in”, while other users simply find it distracting.

Clinical dosing for beta-alanine is 3000 to 6000mg daily, and should be taken every day (even on days you don’t exercise) for longer than 2 weeks to experience its full benefit. 

Swolverine has 3200mg of beta-alanine per serving, meeting clinical dosing standards. 

Betaine Anhydrous

Betaine helps to create L-Carnitine in the body (discussed in more detail just below).

Where exercise is concerned, betaine may improve strength and power output and can improve body composition by reducing fat mass and increasing lean muscle mass. 

The currently accepted clinical dose of betaine is 2500mg daily. Swolverine meets that dose, offering exactly 2500mg of betaine anhydrous per scoop. 

L-Carnitine

L-carnitine has antioxidant and anti-inflammatory properties, meaning it can help reduce muscle damage caused by exercise. 

While L-Carnitine is commonly advertised for fat loss, research shows that its effect is modest at best. 

What you may notice from long-term L-Carnitine supplementation is a reduction in fat mass, increases in workout volume, and improved recovery

Most studies done on L-Carnitine use a 2g dose daily over a several week period. Swolverine only has 1.5g of L-Carnitine, which falls just shy of the clinical dose. 

L-Taurine

Taurine is an amino acid that plays a key role in energy metabolism. It also shows anti-inflammatory and antioxidant properties. 

In regards to exercise, you can notice improved aerobic performance (i.e. you can train longer before feeling fatigue) and improved strength and power output. 

You may also notice reduced muscle soreness after your workouts. 

The clinically accepted dose of Taurine supplementation is 1-3g taken 1 to 3 hours prior to exercise. Swolverine meets clinical dosing standards with a dose of 1.2g per scoop. 

Coconut Water Powder

Coconut water naturally contains sodium, magnesium, potassium, chloride, and glucose making it a great, natural rehydration fluid. 

When added to your preworkout, it adds natural minerals and electrolytes to help support exercise recovery and rehydrate after strenuous exercise. 

There is no definitive clinical dose of coconut water powder, because most studies using coconut water have used actual water and not powder. 

In my professional opinion, it is likely that the dose found in Swolverine will contribute to improved hydration status and recovery.

Siberian Ginseng

Ginseng is a species of small shrub from northeast Asia. 

It’s been clinically studied in doses ranging from 500mg to 1350mg daily and shown to improve cardiovascular function and improve aerobic endurance

When taken as a pre-workout, ginseng may help you workout for longer durations before you feel fatigued, or you may find that you can workout at a higher intensity than normal. 

Swolverine meets clinical dosing standards by offering 1000mg per serving. 

Pomegranate Fruit Powder

Pomegranate is a fruit rich in vitamins, minerals, and antioxidants. 

Some studies have shown that pomegranate supplementation can reduce muscle soreness, increase endurance, enhance blood flow and improve strength and recovery

It’s a bit tougher to explain whether Swolverine meets clinical dosing since a lot of the research uses raw pomegranate juice (not powder).  However, Swolverine does use dosing similar to what is used in a lot of research. 

In my professional opinion, I am confident that you will see some antioxidant and recovery benefits from the 500mg dose of pomegranate fruit powder in this product. 

Highlights: What I Like About Swolverine

Pros vs Cons of taking Swolverine Pre-workout

Stimulant Free

Swolverine is a stimulant-free formula that contains zero caffeine, making it a great option for people choosing not to ingest caffeine, or for people who workout later in the evening and don’t want to disrupt their sleep. 

Even if you don’t workout late in the evening, but you find that traditional pre-workouts make you feel anxious or jittery, Swolverine Pre is a great stim-free alternative.

Good Endurance

I tried Swolverine for resistance training, HIIT, and long distance cardio and felt like I had good stamina and endurance for my cardio-intensive sessions. 

Some ingredients, like beta-alanine and L-carnitine, require you to take it daily for multiple weeks before seeing its full benefit. It’s likely that after several weeks of supplementation with Swolverine, you would notice even more endurance and stamina. 

Sweetened with Stevia

Swolverine doesn’t use any artificial flavors, colors, or sweeteners in its formula. 

Oftentimes, the type of sweetener used comes down to personal preference. That being said, there are artificial flavors and colors in so many other types of food and drink products we consume, it’s nice to have a product that uses naturally sourced flavors in their product. 

Meets Many Clinical Dosing Standards

Swolverine pre workout  - Meets many clinical dosing standards

Swolverine meets clinical dosing standards for 4 out of 6 ingredients which have such levels established: beta-alanine (3.2g), betaine (2.5g), taurine (1.2g), and ginseng (1g). 

The two ingredients that don’t meet clinical standards are citrulline which has 5g out of a clinical dose of 6-8g, and l-carnitine which has 1.5g out of a 2g clinical dose. 

There isn’t a set standard for coconut water powder and pomegranate extract. 

The fact that Swolverine meets clinical dosing standards (or comes close to) for all of its ingredients helps to justify the more expensive cost per serving

Drawbacks What I Did Not Like About Swolverine

Only Available in One Flavor

Swolverine is only available in one size and flavor: 25 servings of Mango Lemonade.

I didn’t mind the flavor, but it is definitely sour. This is common for pre-workouts since a lot of the raw ingredients used are naturally sour or bitter, so companies will try to work with the natural properties of the ingredients. 

If you do not enjoy sour tasting products, then the flavor could be off-putting for you.

It’s on the Higher End of Cost Per Serving

Swolverine Pre is definitely on the more expensive end, with other high quality, clinically dosed pre-workouts like Transparent Labs Bulk and Transparent Labs Stim-Free available for as low as $1.67 per serving.

Transparent Labs Bulk
Transparent Labs Stim Free

However, it can be difficult to compare the cost of pre-workout, since there is so much variability in how many ingredients are included in products, and what kinds of doses are used in the products. 

How Does Swolverine Stack Up Against Our Criteria For Pre Workouts

Price

Our rating: 3/5

Swolverine comes in at $2.12 per serving. I analyzed over 50 different pre-workouts and the mean cost is around $1.61 per serving. 

While this does make Swolverine on the higher end of cost per serving, many other clinically dosed pre-workouts range from $2.20 to $3.00 per serving, making Swolverine a more reasonable option. 

Swolverine Pre

Taste 

Our rating: 3/5

Swolverine is only available in one flavor, Mango Lemonade, which is quite sour. 

I personally happen to like sour flavors, so I didn’t mind this one, but it won’t be for everyone. 

Mixability 

Our rating: 4/5

Overall Swolverine mixed pretty well, with a small amount of undissolved residue in the bottom of my cup. 

Swolverine Pre-workout undissolved residue

Energy

Our rating: 1/5

Swolverine Pre does not provide a substantial amount of energy, but as a stim-free formula, it’s not designed to. 

A response from the Swolverine staff to a review on the Swolverine website outlines this very clearly: 

“The PRE is a ‘non-stim’ pre workout, meaning that it is not designed, formulated, or intended to give you a get up and go, or energy like some other pre workouts, or perhaps ones you have had in the past. This pre workout is designed to increase strength, build more muscle, delay muscle fatigue, and increase performance. Therefore, it is made to be taken for the long-term for results, it’s not meant to be taken one time, then give you great amounts of energy”.

Pump 

Our rating: 3/5

Citrulline Malate, Pomegranate, and Betaine can stimulate the natural release of nitric oxide, so having all three in here does provide a decent muscle pump.

The pump effect was not as substantial as it has been in other products I have tried, possibly due to the slightly lower dose of citrulline malate (5g) compared with other nitric oxide enhancing products which use 6-8g.

Strength

Our rating: 4/5

I noticed during my resistance training sets that I felt like I still had energy in the tank when finishing my prescribed sets and reps with my usual weight.

This is really where Swolverine Pre is designed to shine. Nearly all of the ingredients in Swolverine Pre help to delay time to fatigue (meaning you can workout harder/longer before feeling exhaustion). 

Since some of the ingredients, like beta-alanine, require several weeks of being taken consistently to elicit their full results, it’s very likely that the longer you take Swolverine Pre, the more results you will notice. 

Who Should Take Swolverine? 

Swolverine is for: 

  • People who workout late in the evening and want to avoid caffeine too close to bed time
  • People who consume a lot of caffeine in their day, such as coffee or energy drinks, and don’t want to give those up
  • People who are sensitive to caffeine and stimulants

Who Should Not Take Swolverine? 

I would not recommend Swolverine for:

  • Anyone looking for a high stim product
  • Anyone who doesn’t enjoy sour tasting products

What Are Other Customers Saying About Swolverine? 

On Swolverine’s website, the product has a nearly perfect rating (though based on only 44 reviews which isn’t a great sample size). Reading through the comments, customers praise Swolverine for its great taste and effective pump. 

Customers were enthusiastically claimed that this is one of the best pre-workouts they’ve ever used and that they absolutely love the quality of the product and the pump it provides. 

Some of the only negative feedback I could find from customers related to the fact that it didn’t dissolve entirely in water and that the cost was too high. 

I browsed a few other websites which sold Swolverine Pre to see if I could find different opinions on the product. (In my experience digging into product reviews, I find that people leaving reviews on the company’s actual website tend to be fans of the brand with positively biased reviews). 

Reviews on other websites showed either 4.8/5 or perfect 5/5 star ratings, with customers saying that they like the pump and enjoy that it doesn’t have caffeine to support their late night workouts, but they wish the citrulline content was a bit higher. 

Swolverine Alternatives

Transparent Labs Bulk

Transparent Labs Bulk

If you value high quality ingredients and clinical dosing, but are looking for a product that is caffeinated, I suggest Transparent Labs Bulk

It contains many of the same ingredients as Swolverine Pre including Citrulline Malate (8g), Beta-Alanine (4g), Betaine (2.5g), and Taurine (1.3g), and Ginseng (50mg). 

Transparent Labs Bulk has 200mg of caffeine and alpha-GPC which can both contribute to energy and increased mental focus. 

Like Swolverine Pre, Transparent Labs Bulk contains zero artificial flavors, colors, or sweeteners. It is available in 12 different flavors and only costs $1.66 per serving. 

Transparent Labs Stim-Free

Transparent Labs Stim Free

If you value high quality ingredients with zero artificial additives, but you want to save money on the overall cost per serving then we recommend Transparent Labs Stim-Free Pre-Workout

It contains 6g of citrulline, which is a little bit more than Swolverine, and meets clinical dosing standards for that ingredient. 

Transparent labs Stim Free has doses of beta-alanine (4g), betaine (2.5g), and taurine (1.3g) that are nearly identical to those found in Swolverine. 

While Transparent Labs Stim-Free does not have L-Carnitine or the antioxidant-rich ingredients of coconut water and pomegranate, it does contain a patented ingredient called elevATP which can increase energy, power output, and training volume.

Transparent Labs Stim-Free Preworkout is available for $1.67 per serving, well below the $2.16 that Swolverine costs, and is available in 8 different flavours.
