Why we like Transparent Labs PreSeries Stim-Free as best overall

Transparent Labs PreSeries Stim-Free pre-workout is designed to increase exercise performance, muscle gain, energy, and focus. It contains clinically dosed ingredients like citrulline malate, beta-alanine, betaine anhydrous, and L-tyrosine.

This formula contains 8 grams of citrulline malate per serving to enhance nitric oxide production for better blood flow and nutrient delivery to muscles. Citrulline malate may improve resistance and high-intensity exercise performance, as well as muscle endurance. (

1

)

Beta-alanine (4 grams per serving) and betaine anhydrous (2.5 grams per serving) are both clinically dosed. Beta-alanine is best used for improving the performance of high-intensity exercise lasting from one to four minutes—think explosive movements, lifting sets, and sprints. One thing to note is that you need to supplement with beta-alanine daily for a few weeks to see a difference. (

2

) Betaine has mixed evidence on its efficacy, but it may increase training volume. (

)

Transparent Labs also incorporates L-tyrosine (1 gram per serving) and taurine (1.3 grams per serving)  to help sharpen focus. Tyrosine is an amino acid that can help enhance cognitive function. (

)

Our product tester, a certified personal trainer, tried the cherry limeade flavor. She found it tart and not overly sweet like some other Transparent Labs flavors. However, she found this powder didn’t mix well and left persistent chunks, even in a shaker bottle.

Because of the high dose of beta-alanine, some people may experience tingling skin or itchiness. Although it’s uncomfortable, it is harmless and not an allergic reaction.

Transparent Labs PreSeries Stim-Free formula is, well, transparent—every ingredient on the label is listed with a dose that is not hidden behind a proprietary blend. Moreover, it’s third-party tested through Informed Choice as assurance of no illegal or sport-banned substances.

At $1.67 per serving, this product has a higher price-point than other comparable products on the market, but you may be able to get double the servings by following a recommendation straight from Transparent Labs. The company recommends starting with a ½ scoop serving, instead of the full scoop, due to the potency of the pre-workout. This will extend the life of this product and bring down the cost per serving. Keep in mind, however, that a ½ scoop serving doesn’t provide the same clinically-effective dosages.

What customers are saying

Transparent Labs’ PreSeries Stim-Free pre-workout has garnered 65 reviews on Amazon. Customers enjoy the taste and efficacy of the ingredients, especially when compared to other products, including stimulant pre-workouts, they have tried.

One customer noted this is one of his favorite non-stim pre-workouts, and that a half scoop will be fine for most people.

“I have been wanting to buy this product for a while, but the price is high. However, once I bought this, it was right up there with my favorite preworkouts,” Allister H. wrote. “Since this is effectively dosed, you do not need a full scoop…I am a 240-pound male, I have been working out for over 10 years consistently and heavy, 4-5 times per week, and I have tried tons of pre-workouts, so trust me when I say you don’t need a full scoop.”

An Amazon reviewer named Michael R. also spoke highly of Transparent Labs PreSeries Stim-Free from an ingredient perspective. “Did a ton of research on ingredients and this product by far has the right amount and best ingredients compared to any other product on the market,” he commented.

But, not all customers had the same positive experience. Paul D. noted that the product sparked an unforeseen reaction.

“I had an allergic reaction and they will not do a refund,” he wrote.

  Legion Pulse Stim-Free comes in eight, naturally-sweetened flavors.

  At $2.25 per serving, this product is priced higher than many other choices on the market—but we find the quality worth the cost.

Why we like Legion Pulse as best for cardio

Legion Pulse Stim-Free is specially formulated for those seeking a stimulant-free option without compromising on performance. Packed with clinically tested ingredients, this pre-workout aims to enhance exercise endurance, focus, and muscle pumps.

With 8 grams of citrulline malate per serving, Legion Pulse promotes nitric oxide production and increases blood flow to muscles for improved nutrient delivery and endurance. (

,

)  While both of these ingredients are clinically dosed, more studies are needed to validate their performance-enhancing benefits.

Legion Athletics Pulse Stim-Free is meticulously tested by third-party labs for purity and potency, ensuring each ingredient meets the highest standards. This product has an A- ranking from Labdoor and is certified to contain no banned substances. Plus, it’s made in NSF-certified and cGMP-compliant facilities.

Every ingredient in Stim-Free Pulse is naturally sourced. However, one of the sweeteners used, erythritol, may cause gastrointestinal discomfort for some users, especially at higher amounts. At $2.25 per serving, Legion’s non-stim pre-workout is priced higher than many competitors, but its effectiveness, transparency, and third-party testing justify the cost.

What customers are saying

A majority of Amazon’s 912 reviews of Legion’s Pulse Stim-Free praise its clean ingredients, great taste, and solubility.

“Their product is good (I’ve tried like 8 different preworkouts, Legion is the only one I’ve consistently bought) and the seller is the best,” Aidan wrote. “They’re the kind of company you want to trust your money with, which goes a long way.”

However, a number of reviewers on Amazon noted dislike for the blue raspberry flavor, as well as a tingly and itchy sensation on their hands and ears after consuming Legion Pulse Stim-Free.

“The Blue Razz flavor is awful. I don’t understand all of the positive feedback on the flavor in the comments,” one verified buyer commented. “I immediately felt a pin needle sensation all over my ears and hands as soon as I finished drinking it, which I truly just can’t stand. Had I known it was due to the beta-alanine I wouldn’t have purchased it in the first place, but I have to say with all of the products on the market without it I’m surprised this product contains it, especially the way it’s marketed.”

With the addition of creatine and branched-chain amino acids (BCAAs), Gainful Pre-Workout is designed to support performance and minimize recovery time.

• 
  Gainful Pre-Workout provides the ideal 2:1:1 ratio of leucine, isoleucine, and valine to support muscle protein synthesis.
  
• 
  Although there are only 14 servings per container, a price of $1.86 per serving is slightly lower than other top pre-workouts on the market.
  
• 
  Gainful Pre-workout is best suited for recreational exercisers doing moderate-intensity activity.
  
• 
  Added creatine and BCAAs can reduce or replace the need to buy multiple supplements.
  

Why we like Gainful Pre-Workout as best with BCAAs

Gainful Pre-Workout stands out as a top choice for those prioritizing BCAAs (branched-chain amino acids) and creatine in their supplement stack. This non-stim pre-workout provides 2 grams of BCAAs total, in the ideal 2:1:1 ratio of leucine, isoleucine, and valine to stimulate muscle protein synthesis. (

)

This formula contains 4 grams per serving of citrulline malate, to enhance blood flow and nutrient delivery to working muscles, aiding in endurance and muscle pumps. However, this is not considered a clinically effective dose for exercise performance. Doses ranging from 3 to 6 grams are supported for circulatory health, but the most common dosing strategy for exercise protocols is 6 to 8 grams of citrulline malate. (

7

)

Gainful Pre-Workout also contains 3 grams of creatine monohydrate per serving. Creatine is a well-researched compound known for its ability to increase high-intensity exercise performance. By supplementing with creatine, users may experience improved workout performance, training adaptations, and faster recovery. Plus, 3 grams of creatine taken daily has shown promise with regard to general health benefits. (

8

)

In addition to citrulline, BCAAs, and creatine, this formula includes 1.5 grams per serving of beta-alanine to help buffer lactic acid buildup and delay fatigue during intense exercises lasting one to four minutes. This is also below the clinically effective dose. A range of 4–6 grams of beta-alanine daily is recommended for enhancing exercise performance. (

2

)

Be mindful when purchasing from the Gainful website—they offer a caffeinated and non-caffeinated version of the same product. The website says you can personalize the pre-workout for your needs, but there is only one option if you want the stimulant-free pre-workout.

At $1.86 per serving, Gainful Pre-Workout is priced competitively, especially considering its formula includes BCAAs and creatine. Because there is no mention of third-party testing, this supplement is better suited for fitness enthusiasts and recreational gym-goers.

Nutricost Stim-Free Pre-Workout is a solid and affordable option for those new to using pre-workouts. It helps provide a muscle pump and sharpen focus without caffeine.

• 
  The formula contains 6 grams of L-citrulline, which is clinically effective for boosting pump.
  
• 
  At $1.40 per serving, Nutricost Stim-Free Pre-Workout is the most affordable option we featured and falls well below the average market price for comparable products.
  
• 
  Beta-alanine (1.2 grams) is not a clinically effective dose. However, this might appeal to a beginner, as it likely won’t cause the tingling sensation commonly associated with beta-alanine.
  

Why we like Nutricost as best for beginners

For gymgoers trying pre-workout for the first time, Nutricost Stim-Free Pre-Workout provides an effective muscle pump and energy boost thanks to key ingredients like L-citrulline and B vitamins.

Nutricost contains 6 grams of L-citrulline per serving, which is a clinically studied dose. L-citrulline helps enhance exercise performance by increasing nitric oxide production for improved blood flow and nutrient delivery to muscles. (

1

)

The formula also includes energy-enhancing ingredients like vitamins B1, B3, B6, and B12. The B vitamins, in particular, help your body use energy from food. (

15

) In addition to this boost, the Nutricost formula contains L-tyrosine (500 milligrams per serving) and taurine (1.2 grams per serving)  to help improve cognitive function and focus during exercise. (

4

)

While Nutricost’s 1.2-gram dose of beta-alanine is lower than the recommended 3.2-6.4 gram clinically effective dose, it may appeal to beginners. High doses of beta-alanine can cause a tingling sensation that, while harmless, could be alarming to people trying pre-workout for the first time. (

2

)

We did find it slightly confusing that the different flavors of Nutricost’s stim-free pre-work have different ingredient labels. The pink lemonade and peach mango ingredient labels include evodiamine, whereas the blue raspberry contains thermodiamine. The blue raspberry flavor also contains betaine anhydrous (2 grams), which is not included in the pink lemonade or peach mango supplement facts.

Additionally, the blue raspberry has a bigger serving size (18 grams) than the other two flavors (15 grams). The same flavor on Amazon shows 15 grams per serving and the same ingredients as the pink lemonade and peach mango.

Nutricost Stim-Free is made in an FDA-registered facility that is GMP Compliant. However, there is no indication of third-party testing. For a beginner, this isn’t much of a concern, but we recommend serious athletes who might be more vigilant about their pre-workout routine stick to third-party tested supplements.

At just $1.40 per serving, Nutricost Stim-Free Pre-Workout comes in well under the average market price for this category and is the least expensive option we featured. Nutricost also offers a 60-day money-back guarantee.

What customers are saying

Nutricost Stim-Free Pre-Workout has garnered 642 reviews on Amazon. Buyers like the performance and ingredients for the price. Opinions were mixed on the taste.

“Mixes well, no clumps, taste is a bit sweet so add plenty of water. Otherwise, it is tangy and mixes nicely with my creatine,” wrote a verified Amazon buyer with the username RRE.

But, not everyone felt the pre-workout achieved the desired result. “No energy given. Felt absolutely nothing. Within an hour of my workout, I felt so tired and had zero energy,” verified Amazon customer Michelle wrote.

• 
  Jacked Factory Pump Surge Stim Free is the only non-stim pre-workout we featured without beta-alanine.
  
•

Why we like Jacked Factory Pump Surge Stim Free as best for pump

Jacked Factory Pump Surge Stim Free is a standout option for exercisers seeking a caffeine-free muscle pump. The formula blends 8 grams of L-citrulline with 2 grams of Glycerpump™, which the company claims boosts nitric oxide levels, hydrates the muscles, and promotes muscle fullness. Glycerpump is a trademarked ingredient that contains 65% glycerol powder to enhance water retention. One thing to note, glycerol can make you feel heavier, and it is also used as a laxative to relieve constipation. (

This formula contains 1 gram of L-tyrosine and 125 micrograms of huperzine A per serving which plays a functional role in cognitive function and focus. Huperzine A is used in Chinese folk medicine to treat dementia. It works by increasing levels of the neurotransmitter acetylcholine in the brain, which may enhance cognitive function, focus, and memory. For gym-goers, supplementation could help optimize mental clarity and concentration during workouts. (

There could be some confusion surrounding Jacked Factory’s labels and directions on their website. The Pump Surge Stim-Free container says it contains 30 servings and recommends taking one scoop (8.35 grams), but the label on the website says it contains 15 servings and that one scoop is 16.7 grams. In the FAQ section of the website, Jacked Factory recommends taking one or two scoops of Pump Surge before a workout. You have to use the two-scoop serving to get the clinically effective dose of citrulline and betaine.

If you purchase directly from the Jacked Factory website, Pump Surge costs $34.99, but if you purchase from the Jacked Factory store on Amazon, the price is $19.99. One thing to note is that Jacked Factory does have a 30-day money-back guarantee, but Amazon does not allow returns of this product.

Priced at $2.33 per serving, this is the most expensive stimulant-free pre-workout on our list. We’d love to see a product at this price-point include third-party testing and do away with the artificial flavors and sweeteners in the formula.

What customers are saying

Jacked Factory Pump Surge Stim-Free has 5,027 reviews on Amazon, with many customers commenting on a noticeable pump, as well as great pre-workout energy and focus without jitters or face tingling.

Verified customer Kenpo S. commented, “I like this product. It provides enough help to power through my workout but does not leave residual jitters afterward. It is a little pricey, though.”

On the other hand, some Amazon reviewers were not impressed with the pump or the cherry limeade flavor.

“I’ve tried a few different non-stim pre-workout supplements, and this is easily the worst I’ve had,” commented Grant. “[There was] little to no noticeable impact on energy/duration of workout, and the flavor I ordered (cherry limeade) was gross.”

Why we like Gnarly Sports Nutrition Pre-Workout as best all-natural

Gnarly Sports Nutrition Pre-Workout offers an all-natural stimulant-free option for those looking for muscle pumps and a boost of energy without the jittery side effects of caffeine.

This is an NSF Content Certified Product, meaning it’s been third-party tested and isn’t contaminated with heavy metals, microbes, or pesticides. Plus, there are no proprietary blends, so you know exactly how much of each ingredient is inside.

Gnarly’s website says the ingredients are in dosages that are proven to be effective. However, the recommended dose of citrulline malate to enhance sports performance is 6 to 8 grams. This pre-workout contains 5 grams per serving. Citrulline malate is used to increase blood flow to working muscles. (

7

)

Likewise, 3.2-6.4 grams per day of beta-alanine is recommended for enhancing exercise performance, but Gnarly Pre-Workout contains 2.5 grams per serving. You need to supplement with it daily for a few weeks to really notice a difference. More research is needed to determine the effects of beta-alanine on strength and endurance performance beyond 25 minutes in duration. (

Gnarly Pre-Workout contains the ideal 2:1:1 ratio of leucine, isoleucine, and valine, with a total of 4 grams of vegan BCAAs per serving to stimulate muscle protein synthesis. It also includes 150 milligrams of Asian Ginseng root powder to naturally boost energy. Asian ginseng is believed to reduce fatigue and enhance endurance during exercise. Its adaptogenic properties may also help the body better cope with stress, aiding in overall performance and recovery. (

Pay attention while shopping—the website offers a caffeinated and non-caffeinated version of the same product. The product descriptions on the website are for the caffeinated versions, which can be confusing for customers. To find the supplement facts and ingredients for the caffeine-free pre-workout, you have to scroll through the product images. There’s also mention of 100 milligrams of ginger in the product descriptions, but it’s not listed on any of the labels.

At $1.50 per serving, Gnarly Sports Nutrition Pre-Workout is one of the most affordable options we featured. And the addition of BCAAs makes the price even more desirable since you’re basically getting two supplements in one.

What customers are saying

The 147 Amazon reviews associated with the Gnarly Pre-Workout regularly comment on the high-quality of ingredients. However, it’s impossible to tell from the reviews who used the caffeinated version versus the non-caffeinated one.

Some Amazon buyers, like Casey E., didn’t realize there was a version with caffeine, and they weren’t happy when they figured that out. “I didn’t realize this, but there are two ingredients in the strawberry lemonade version called beta-alanine and caffeine. The beta-alanine caused itching, and my son also reported feeling more tired on this version.”

Fermented L-citrulline helps enhance blood flow and muscle pumps by boosting nitric oxide production. Beta-alanine helps to increase muscle endurance by fighting muscle fatigue, and betaine may help increase power output.

Kaged Pre-Kaged includes 100 milligrams of Spectra™, a trademarked blend containing 29 superfood antioxidants. Because it’s a proprietary blend, it’s impossible to know how much of each ingredient is in it or what effect it has on your performance. Some of the herbs may not be suitable for all people. Plus, with so many extra ingredients delivered at a combined level of 100mg, it’s hard to predict performance benefit, if any. But the product is also Informed-Sport Certified, meaning it’s guaranteed safe from banned substances.

There are also very high doses of vitamins B6 and B12 in the Pre-Kaged mix. B vitamins are water-soluble and quickly leave your body when you urinate, but that doesn’t mean you should supplement with them beyond the sound daily recommendations for people who exercise seriously. This formula contains 20,833% of the daily value for vitamin B12 and 1,417% of the daily value for B6, likely higher than necessary to optimize body status, even for the heaviest training schedules. However, the levels are still well within tolerable ranges and pose no major safety concerns

Our tester, a certified personal trainer, tried the cherry bomb flavor. He felt like it fell flat and tasted artificial. “Not offensive, just not the best. To be honest, I couldn’t really tell it was supposed to be cherry-flavored.”

Taste aside, he said the pump was incredibly strong. “I was working on a heavy top set after taking this, and the after-effects were very apparent. I hate that there are only 20 servings, and the scoop is very large compared to other pre-workouts, but that’s because there are quite a few compounds in here. I love having this for afternoon workouts.”

Although Kaged Pre-Kaged Stim Free doesn’t contain artificial colors, flavors, or dyes, it does contain sucralose, an artificial sweetener.

At $2.25 per serving, Kaged Pre-Kaged Stim Free is priced above average for this category.

Why we like 1st Phorm Endura-Formance as best with creatine

With a clinically-effective dose of creatine monohydrate, beta-alanine, and betaine in every serving, 1st Phorm Endura-Formance is a powerhouse non-stim pre-workout supplement.

Creatine and beta-alanine are both known for increasing high-intensity exercise performance. Creatine increases the availability of phosphocreatine, which helps rapidly regenerate ATP (adenosine triphosphate), the primary energy currency of cells, during high-intensity activities. Beta-alanine helps to reduce lactic acid and improve muscle endurance. Plus, combining creatine with beta-alanine may enhance effectiveness.  (

Endura-Formance contains two proprietary blends. Peak02™ is a blend of adaptogenic mushrooms that are supposed to help you overcome physical and mental stress. S7® is a blend of nitric oxide-boosting ingredients. As we’ve already mentioned, the problem with proprietary blends is you don’t know how much of each ingredient you’re getting in the supplement. So you can’t always know what effect, if any, it has on your performance.

Our tester, a certified personal trainer, ordered the berry lemonade and said it was easily one of the best-tasting supplements she tried in this round of product testing. “Not too sweet, slightly tart, no weird aftertaste. This mixes well in both a water bottle and in a shaker bottle. No noticeable chunks or grainy bits.”

She also said Endura-Formance is a great addition to her supplement stack. “I love taking this before all types of workouts, but especially endurance workouts since it has ample sodium. It also contains the clinical dosage of creatine, which is awesome to see, plus beta-alanine, betaine anhydrous, and L-tyrosine, all great ingredients in pre-workout.”

At $1.50 per serving, this is one of the most affordable stimulant-free pre-workouts in our round-up. Plus, it contains a full clinically effective dose of creatine, so you’re getting even more bang for your buck. 1st Phorm also has a 110% money-back guarantee, which shows how much the company stands behind its products. If you don’t love the product, you can return it for a 110% refund (minus the cost of shipping).
