The best pre-workout supplements of 2026

Pre-workout, ranked on the two things you can check for yourself: whether the exact tub is listed in a banned-substance certifier's public register, and what its own supplement facts panel says the doses are.

Every dose below was read off the maker's own panel, and every certification was looked up in the certifier's database rather than taken from the brand. Two findings run through the whole page. All five of these products print every dose on the label, so the usual advice to avoid proprietary blends does not sort them at all. And the number on the tub is not always the number in the tub: 8,000 mg of citrulline malate is about 5,300 mg of actual citrulline, because malic acid makes up the other third of it.

EDITOR'S CHOICE

Transparent Labs

Transparent Labs BULK Pre-Workout

9.6/10JellyReviews Score

Two products on this page are in a certifier's public register, and this is the one that did not give anything up to get there. Informed Choice, run by LGC, lists it as "Bulk Pre-Workout", which means the tub is screened against a banned-substance list rather than simply claiming to be clean. The other certified option, Cellucor's C4 Ripped Sport, contains no citrulline whatsoever. This one carries 8,000 mg of citrulline malate and the largest beta-alanine dose here at 4,000 mg, and pairs its 200 mg of caffeine with 200 mg of L-theanine. So you are not choosing between a clean label and a real formula. The catch is commercial rather than nutritional, and we would rather say it than hide it. Transparent Labs pays us nothing.

Pros

Informed Choice lists it by name in their public register, as "Bulk Pre-Workout", so the exact tub is screened against a banned-substance list rather than just claiming to be clean

It is the only certified product here that does not pay for the certificate with its formula. The other certified one, C4 Ripped Sport at rank 2, contains no citrulline at all

4,000 mg of beta-alanine, the most on this page, plus 8,000 mg of citrulline malate 2:1, which Legion matches and nothing here beats

200 mg of caffeine paired with 200 mg of L-theanine, which is the combination people reach for when caffeine alone makes them jittery. Sweetened with stevia, with no sucralose, no acesulfame potassium and no added color

Cons

JellyReviews earns nothing if you buy this. We have no affiliate relationship with Transparent Labs, and the button below goes straight to their product page with no tracking on it

That citrulline malate 2:1 is roughly 5,300 mg of actual citrulline once you take out the malic acid, which is less than the 6,000 mg of pure citrulline Ghost puts in at rank 4

Stevia tastes like stevia. If you have bounced off it before, this will not be the tub that changes your mind

Cellucor

Cellucor C4 Ripped Sport Pre-Workout, Arctic Snow Cone, 20 Servings

9.3/10JellyReviews Score

Here is the thing almost nobody buying C4 knows: Cellucor sells an NSF Certified for Sport pre-workout, and it is not the one on every shelf. Search NSF's register for Cellucor and you get C4 Sport and C4 Ripped Sport. You never get C4 Original. So if you are drug-tested, the brand you already trust has a version that has been screened for you, sitting next to the one that has not. What the certification costs you is the pump ingredient: this tub has no citrulline, only 2 g of arginine. For a tested athlete that is a trade worth making. For everyone else, it probably is not.

Pros

NSF Certified for Sport, which is the mark most US college and professional leagues actually name. NSF lists it, Informed Choice lists it, and Cellucor prints it on the tub and in the Amazon title

Every dose is disclosed, and the named matrices add up exactly: the 5.25 g Performance Booster is 2 g beta-alanine plus 2 g L-arginine plus 1.25 g betaine, and nothing is left over

200 mg of caffeine, the same as Transparent Labs and 150 mg less than Legion

Zero sugar, and the color comes from spirulina extract rather than a dye

Cons

It contains no citrulline at all. Cellucor uses 2 g of L-arginine instead, which is the older and weaker way to chase the same pump. This is the real price of the certification

20 servings per tub. Only Legion is as small; Transparent Labs, Ghost and C4 Original all give you 30

This is the thermogenic version, so it carries cayenne extract and 2 g of carnitine. If you just want a pre-workout, that is cargo you did not ask for

MOST CAFFEINE

Legion

Legion Pulse Pre-Workout

9.1/10JellyReviews Score

The hardest-hitting tub here, and the one to reach for if caffeine is the point. Legion matches Transparent Labs on citrulline at 8,000 mg of citrulline malate, comes within 400 mg of it on beta-alanine, and then puts 350 mg of caffeine on top, the most on this page, buffered with an equal 350 mg of L-theanine. Legion is also unusually open about testing: it publishes a Labdoor grade and prints the comparison table on its own product page, which almost no brand does. Be precise about what that grade is, though. Labdoor checks that the label is accurate. It is not a banned-substance screen, and Legion appears in none of the three registers. Right for a lifter, wrong for anyone who gets tested.

Pros

8,000 mg of citrulline malate and 3,600 mg of beta-alanine, matching Transparent Labs on citrulline and coming within 400 mg on beta-alanine

350 mg of caffeine, the most on this page, buffered with 350 mg of L-theanine

Legion publishes a Labdoor third-party test result and an A grade for the product, and puts the comparison table on its own product page

Naturally sweetened and flavored, with no artificial food dyes

Cons

350 mg of caffeine is a lot. If you drink coffee in the morning you can reach the FDA's 400 mg daily ceiling on one scoop and one cup

A Labdoor grade is not a banned-substance certificate. Legion appears in none of the three registers, so a tested athlete cannot use this

It contains no creatine, which Legion states plainly. You will need to take that separately

Ghost

GHOST LEGEND V4 Pre-Workout, Blue Raspberry

8.9/10JellyReviews Score

Read the two labels side by side and the ranking most sites give this product falls apart. Ghost puts 6,000 mg of pure L-citrulline in a scoop. Transparent Labs and Legion each put in 8,000 mg of citrulline malate 2:1, which is about 5,300 mg of citrulline once you subtract the malic acid. Ghost is therefore delivering more of the ingredient people buy pre-workout for, from the smaller-looking number. Two real reasons it sits at 4 rather than 1. The powder is not in any banned-substance register, and it is not on Amazon, so buying it means going direct and we earn nothing when you do.

Pros

6,000 mg of pure L-citrulline, which is more actual citrulline than the 8,000 mg of citrulline malate at ranks 1 and 3 once the malic acid is taken out

3,200 mg of beta-alanine and 300 mg of natural caffeine, both inside the ranges the research uses

The whole panel is printed, ingredient by ingredient, with no grouped matrix to hide behind

2,000 mg of L-tyrosine and 400 mg of choline, both the largest on this page, if focus is what you take a pre-workout for

Cons

Not sold on Amazon. Searching for it returns GHOST Energy cans and nothing else, so the button below goes to Ghost, and it earns JellyReviews nothing

The powder is in none of the three registers. NSF does certify GHOST Energy, the canned drink, which is exactly the kind of near-miss that gets read as certification when it is not

Sucralose and artificial flavoring, which is the trade for the flavors people buy it for

Cellucor

Cellucor C4 Original Pre-Workout, Icy Blue Razz, 30 Servings

8.4/10JellyReviews Score

The best-selling pre-workout in America, and the only product here that is neither certified nor well dosed. The current fifth-generation panel gives you 1,200 mg of L-citrulline. Ghost gives you 6,000 mg. That is a fivefold gap in the one ingredient that produces the pump people buy pre-workout for, and no amount of flavor variety closes it. C4 Ripped Sport also drops the citrulline, but it gets the NSF mark in exchange. This tub gets nothing in exchange. Two things in its favor, and they are real: it is the only product here with creatine in it, and it prints every dose, which the internet still insists it does not. If C4 is what you know and like, the honest upgrade is not a different brand. It is C4 Sport, from Cellucor, with the NSF mark on it.

Pros

The easiest of the five to actually buy, in more flavors and more shops than the rest of this page put together

1 g of creatine nitrate, and it is the only product here that includes any creatine at all

200 mg of caffeine and 2 g of beta-alanine, both printed on the panel

Zero sugar, and the color comes from vegetable juice and beta-carotene rather than a dye

Cons

1,200 mg of L-citrulline, a fifth of what Ghost puts in and far below the 8,000 mg of citrulline malate at ranks 1 and 3. Of the four products here that contain citrulline at all, this is by a wide margin the smallest dose

Cellucor's own C4 Sport and C4 Ripped Sport are NSF Certified for Sport. C4 Original is not, and it is the one everyone buys

2 g of beta-alanine is under the 3,200 mg Ghost reaches and the 3,600 mg Legion reaches, so the endurance ingredient is short too

§ 03 · Buying guide

How to choose the right pre-workout supplement

01Citrulline malate is not citrulline, and the gap is a third

This is the single most useful thing on this page, and it is arithmetic anyone can do. Citrulline malate 2:1 means two parts citrulline to one part malic acid by weight. So the 8,000 mg on the Transparent Labs and Legion panels is roughly 5,300 mg of actual citrulline. Ghost prints 6,000 mg of pure L-citrulline, a smaller number that delivers more of the thing you are buying.

Nobody is cheating here. Both forms are legitimate and both are on the label in plain sight. But the two numbers are not comparable as printed, and every brand knows which of the two makes their tub look bigger. When you compare pre-workouts, convert everything to actual citrulline first, or you are comparing marketing.

02The proprietary blend is not the problem it used to be

The standard advice is to avoid any label with a proprietary blend, because a blend lets a brand pad the total with cheap taurine and put a sprinkle of the expensive stuff on top. It is good advice, and it did not sort a single product on this page. All five print every dose.

C4 is the one people still name as the offender, so check it yourself. The panel groups ingredients into a 4.5 g Performance Booster and a 205 mg Energy Complex, then lists each component underneath: 2 g beta-alanine, 1.2 g citrulline, 1.2 g arginine, 100 mg peptides, and 200 mg caffeine plus 5 mg of huperzia. Add them up. They come to exactly 4.5 g and 205 mg. A named group with every dose printed under it is not a hidden blend, and treating it as one lets you miss the thing that actually is wrong with C4 Original, which is that 1.2 g of citrulline is a fifth of what the competition gives you.

03If you are drug-tested, the register decides, and it is not the brand

Three databases are public and searchable, and they do not overlap: NSF Certified for Sport at nsfsport.com, and Informed Sport and Informed Choice at wetestyoutrust.com. A product is either listed or it is not. Searching one and stopping is how you end up saying a certified product is uncertified.

On this page they settle everything in minutes. Transparent Labs BULK is in Informed Choice. C4 Sport and C4 Ripped Sport are in NSF and Informed Choice. Legion, Ghost Legend and C4 Original are in none of the three. Watch for the near-miss, because it is designed to be one: NSF certifies GHOST Energy, the canned drink, not GHOST LEGEND, the powder. Same brand, same shelf, different product, and only one of them has been screened.

§ 04 · FAQ

Questions about pre-workout supplements

No. Pre-workout gives you caffeine for energy and focus, and citrulline for blood flow. Neither builds muscle directly. Training and protein do that. What a pre-workout buys you is a better session, and the two ingredients doing most of the work are cheap on their own: caffeine, and creatine monohydrate at 5 g a day. Notice that only one product on this page contains creatine at all, and only 1 g of it. If you want the pump ingredient and the strength ingredient, you are buying two things regardless.

That is paresthesia, and it is harmless. Beta-alanine stimulates nerve endings under the skin, usually across the face, neck and hands, and it fades within about half an hour. Doses above roughly 800 mg are where most people start to notice it, and every product on this page is well above that: 2,000 mg at the lowest and 4,000 mg at the highest. The tingle is not a sign the product is working and it is not a sign of dose accuracy either. If it bothers you, split the scoop in half and take it twice.

The FDA says 400 mg a day is not generally associated with negative effects in healthy adults. The products here run from 200 mg to 350 mg per scoop, so a single serving is inside that. The trap is everything else. One scoop of Legion Pulse at 350 mg plus a large coffee puts you at the ceiling before lunch. Start with half a scoop of anything new, and count the coffee.

No, and this is the confusion the supplement aisle runs on. Labdoor tests whether the label is accurate, which is worth knowing and which Legion publishes openly. NSF Certified for Sport and Informed Sport screen each production lot against a list of substances banned in competition, and they publish the result in a database you can search by brand. One tells you the tub contains what it says. The other tells you it does not contain something that would end your season. If you are tested, only the second one counts.

The verdict

Transparent Labs BULK is our top pick. Two products here are in a certifier's public register, and it is the one that gave nothing up to get there: the other, C4 Ripped Sport, has no citrulline at all. If you are drug-tested and want to stay with a brand you already know, C4 Ripped Sport carries the NSF mark, and the thing worth knowing is that C4 Original, the tub everybody actually buys, does not. If nobody tests you, look hard at Ghost Legend. Its 6,000 mg of pure L-citrulline is more of the pump ingredient than anything else on this page delivers, whatever the bigger numbers printed on the other tubs suggest.
