If you like Transparent Labs, you like a fully disclosed label with no artificial sweeteners or dyes and real testing behind it. Ten brands hold that same standard: Legion, Kaged, Momentous, and Naked lead the pack, with Promix, Xwerks, Jacked Factory, Gnarly, Truvani, and Create close behind across pre-workout, protein, and creatine.
Transparent Labs earned its reputation on one thing: it shows you every ingredient and every dose, skips the proprietary blends, and leaves out the artificial sweeteners most brands hide behind. People usually go looking for an alternative for a plain reason, price, flavor, or a need for a specific certification, not because the formulas let them down. So this list is organized around the closest clean swaps, and further down we match each reason you might switch to the brand that fits it. Most of these are direct-to-consumer stores you can buy from in two clicks, and they show up again on our roundup of the best DTC supplement brands.
How we picked these brands
- Fully disclosed doses. Every ingredient and its exact amount on the label, no proprietary blends. This is the Transparent Labs promise, so it was the first filter.
- No artificial sweeteners or dyes. The main reason shoppers choose clean brands. Anything sweetened with sucralose or colored artificially did not make the cut.
- Third-party or NSF testing. A claim on a bag is not proof. We favored brands that publish testing or carry NSF Certified for Sport or Informed Sport certification.
- Real heroes across the lineup. Transparent Labs shoppers buy pre-workout, protein, and creatine, so each brand needed a credible product in at least one of those, ideally more.
- Direct-to-consumer with a track record. Established brands with real reviews and their own store, not marketplace filler.

1. Legion Athletics
Legion Athletics is the closest thing to a straight swap. The formulas are dosed at the levels used in peer-reviewed research, sweetened naturally with no artificial flavors or dyes, and third-party lab tested for purity. Whey+ protein and Pulse pre-workout are the two products people cross-shop against Transparent Labs most often, and the philosophy is nearly identical.
Best for anyone who wants the same fully dosed, naturally sweetened approach across their whole shelf. If you want to see how Legion stacks up against its own competition, we broke down brands like Legion in a separate guide. Prices sit in the mid-premium range, similar to Transparent Labs.
2. Kaged
Kaged is Informed Sport verified, which means the products are tested for hundreds of banned substances and heavy metals, not just purity. The lineup is broad and clinically dosed, with Pre-Kaged pre-workout, whey isolate, and patented ingredient forms like Creatine HCl and PurCaf caffeine.
Best for drug-tested athletes who want a full, banned-substance-screened range from a single brand. It lands in the mid price tier, and the testing paperwork is easy to find on the site.
3. Momentous
Momentous is the premium pick. Its core products are NSF Certified for Sport and third-party tested with public Certificates of Analysis, and its supplements are used by teams across the NFL. The range leans toward clean single-ingredient staples like creatine, whey, and collagen rather than flashy blends.
Best for competitive athletes and anyone who wants the strongest certification on the shelf and will pay for it. If you are comparing it to similar premium brands, see our list of alternatives to Momentous.
4. Naked Nutrition
Naked Nutrition built its whole identity around short ingredient lists. Naked Whey is a single ingredient, grass-fed whey, with no artificial sweeteners, flavors, or colors, and the brand publishes independent lab testing.
Best for minimal-ingredient purists and shoppers who want clean protein without a premium price. It sits in the budget-to-mid range, which makes it one of the more affordable ways to match the Transparent Labs standard on protein specifically.
5. Promix Nutrition
Promix Nutrition makes one of the shortest pre-workouts you can buy: six ingredients, NSF Certified for Sport, with a full 3.2 grams of beta-alanine and 200 milligrams of caffeine and no artificial sweeteners. Its grass-fed whey follows the same stripped-down approach.
Best for shoppers who want the absolute shortest ingredient list with real certification behind it. It is a mid-priced brand with more than 275,000 customers, so the reviews run deep.
6. Xwerks
Xwerks keeps its catalog small on purpose. Grow is a whey isolate made from New Zealand grass-fed cows with 25 grams of protein and over 6 grams of BCAAs per serving, Lift is micronized creatine monohydrate, and Ignite covers pre-workout.
Best for anyone who wants a tight set of grass-fed staples without scrolling through fifty products. Pricing is mid-premium, in line with the grass-fed sourcing.
7. Jacked Factory
Jacked Factory proves you can get a fully disclosed label at a budget price. Nitrosurge is its hero pre-workout, with every dose printed on the tub, and reviewers consistently describe smooth energy without a crash. It also runs a solid protein and creatine line.
Best for budget shoppers who still refuse to buy a proprietary blend. If pre-workout is your main reason for shopping, it is worth comparing against the wider field in our best pre-workout brands guide.
8. Gnarly Nutrition
Gnarly Nutrition carries NSF Certified for Sport on both its whey and its clean pre-workout, and it offers a genuinely good vegan protein for people who skip dairy. The brand skews toward endurance and outdoor athletes.
Best for drug-tested athletes who want NSF-certified whey, and for anyone who needs a plant-based option that still tests clean. It sits in the mid price range.
9. Truvani
Truvani is the label-reader's brand. Founded by food activist Vani Hari, it uses grass-fed whey and plant protein with no artificial sweeteners, colors, or fillers, and it keeps ingredient lists short and recognizable.
Best for shoppers who read every panel and want the fewest, most familiar ingredients. It is mid-premium, and the trade-off for that price is a very clean, very simple formula. For a fuller field of clean protein options, see our best protein powder brands roundup.
10. Create
Create solves the one supplement people hate mixing: creatine. It sells third-party tested creatine monohydrate as a gummy and an easy mix, independently checked for purity and potency, so you get a clinically studied staple without the powder clumps.
Best for anyone who wants clean, tested creatine in the simplest possible format. It sits in the mid price tier, and if creatine is your priority you can compare the whole category in our best creatine brands list.
How to choose a Transparent Labs alternative
Start with why you are switching. If you just want the closest match with the least thinking, go with Legion Athletics, since the naturally sweetened, fully dosed approach is nearly the same. If price is the issue, Jacked Factory and Naked Nutrition hold the clean standard for less.
If you are drug-tested or want the strongest proof, choose an NSF Certified for Sport or Informed Sport brand: Momentous, Kaged, Gnarly, or Promix. If your rule is the fewest possible ingredients, Naked Nutrition, Promix, and Truvani win. And if you are only after one product, match it to a specialist, Create for creatine, Promix or Jacked Factory for pre-workout, Xwerks or Truvani for grass-fed whey.
Frequently asked questions
What makes a supplement brand like Transparent Labs?
Three things: a fully disclosed label with exact doses and no proprietary blends, no artificial sweeteners or dyes, and real third-party or NSF testing. Every brand here clears that bar, which is why they read as true alternatives rather than random swaps.
Is Legion better than Transparent Labs?
Neither is clearly better. Legion and Transparent Labs share almost the same philosophy, clinically dosed formulas, natural sweeteners, and third-party testing, so it usually comes down to flavor preference and which specific products you buy most.
Which Transparent Labs alternative is cheapest?
Jacked Factory and Naked Nutrition are the most budget-friendly while still keeping a clean, fully disclosed label. Jacked Factory is strong on pre-workout, and Naked Nutrition is hard to beat on plain grass-fed protein.
Are these brands third-party tested?
Yes, testing was a selection filter. Momentous, Kaged, Gnarly, and Promix carry NSF Certified for Sport or Informed Sport certification, and the rest publish independent lab testing for purity and potency.
What is the closest clean pre-workout to Transparent Labs BULK?
Legion Pulse is the nearest match on philosophy, with clinical doses and natural sweeteners. Promix and Jacked Factory Nitrosurge are strong runners-up, and Promix adds NSF Certified for Sport if certification matters to you.
Which alternative is best for drug-tested athletes?
Look for NSF Certified for Sport or Informed Sport on the label. Momentous, Kaged, Gnarly, and Promix all carry one of those certifications, which screen for banned substances beyond basic purity testing.
Do any of these avoid artificial sweeteners like Transparent Labs?
All of them do. Avoiding artificial sweeteners and dyes was a hard requirement for this list, so whether you pick Legion, Naked Nutrition, Truvani, or any other brand here, you are getting a naturally sweetened or unflavored product.
