Legion built its name on natural sweeteners and evidence-based marketing. Here is what Whey+, Casein+ and Plant+ actually deliver per scoop, what Labdoor testing does and does not cover, and which tub is worth your money.

**How we rank:** We judge every powder on the label, not the marketing: protein per scoop, cost per 25 g of protein, the full ingredient list and third-party testing. No paid placements, and commission never sets a ranking. [Read our methodology](https://www.best-proteinpowder.com/how-we-test/)

Legion Whey+ is a good grass-fed whey isolate: 22 g of protein in about 100 calories, Irish dairy, stevia instead of sucralose, and a no-return money-back guarantee. It is not a certified sport product, and it costs roughly $2.50 per 25 g of protein, so it suits the recreational lifter who wants a clean label more than the drug-tested athlete or the bargain hunter. The rest of the range is uneven, and Casein+ in particular has less protein per scoop than its marketing suggests.

## 1. The Short Verdict

Buy **Legion Whey+** if you want a straightforward grass-fed whey isolate with no artificial sweeteners and you are not subject to drug testing. One scoop delivers 22 g of protein in about 100 calories, with roughly 2 g of carbohydrate and almost no fat, per a retailer supplement-facts panel at the time of writing. The whey comes from Irish dairy farms and Legion describes it as Truly Grass Fed certified. It is a credible pick on our [best whey protein isolate](https://www.best-proteinpowder.com/best-whey-protein-isolate/) list for buyers who prioritize a stevia-sweetened label.

It is not cheap. At typical retail prices of about $65 to $70 for a 30-serving tub, Whey+ costs roughly $2.50 per 25 g of protein. That is around 70 percent more than a mainstream whey blend, and slightly more than a higher-dose certified isolate such as Transparent Labs. You are paying for the sourcing and the natural sweetener system rather than for extra protein.

Legion's testing story is also weaker than its marketing language suggests. The brand says its products are independently certified by Labdoor and made in NSF-certified facilities. Neither of those is the same as NSF Certified for Sport or Informed Sport product certification, which is what drug-tested athletes need. If that matters to you, look elsewhere.

The rest of the range: **Plant+** is a solid pea and rice blend with 24 g of protein per serving. The plain **whey concentrate** is Legion's budget option at 20 g. **Casein+** lists 21 g of protein on its supplement-facts panel, fewer than the 25 g headline figure that appears in some places, which is the single most important thing to know before buying it.

> **Legion Whey+ at a Glance**
>
> - **22 g**: Protein per scoop (label)
> - **100**: Calories per scoop
> - **Stevia**: Sweetener; no sucralose
> - **~$2.50**: Per 25 g protein, approx.

## 2. Who Makes Legion

Legion Athletics was founded by Mike Matthews, a fitness author best known for the book Bigger Leaner Stronger, who used the success of his books to launch the supplement company and remains its chief executive. The brand's identity is evidence-based marketing: product pages lean on study citations and long explanations of why each ingredient is there, and the company has long promoted itself as using only natural sweeteners and flavors.

That positioning shows up on the labels. Every Legion protein is sweetened with stevia, often alongside monk fruit or allulose, rather than sucralose or acesulfame potassium. Flavors come from natural flavoring, and the protein sources are named specifically: Irish grass-fed whey isolate in Whey+, micellar casein from Irish grass-fed milk in Casein+, PURIS pea and organic brown rice in Plant+.

Legion also offers a money-back guarantee that does not require you to return the product, according to its product pages. That lowers the risk of trying a flavor you might dislike, which matters more than usual here because stevia-sweetened powders divide buyers. Some people find stevia's aftertaste noticeable; others prefer it to sucralose.

Legion sells primarily through its own website, but its proteins are also stocked by large retailers including Vitacost, iHerb, GNC and Kohl's, and by Amazon. Pricing and availability vary a lot between these channels, and several flavors were listed as temporarily unavailable at major retailers at the time of writing, so it pays to compare before ordering.

## 3. The Legion Protein Range, Ranked

Legion sells four protein powders at the time of writing: Whey+, a cheaper whey concentrate, Casein+ and Plant+. They are ranked below for the job of hitting a daily protein target, followed by two alternatives from other brands. Figures come from Legion's product pages and retailer supplement-facts panels at the time of writing and vary by flavor, so check the tub you buy. The ranking is built on label analysis, testing status and approximate cost per 25 g of protein, not on our own lab or taste tests.

### 1. Legion Whey+ Grass-Fed Whey Isolate

**Award:** Best Overall | **Type:** Grass-fed whey protein isolate

- **Protein per serving:** 22 g (label; varies by flavor)
- **Calories:** About 100
- **Third-party testing:** Labdoor-certified brand (per Legion)
- **Best for:** Stevia-only isolate buyers

Legion's flagship is whey isolate from Irish dairy farms, which Legion describes as Truly Grass Fed certified, sweetened only with stevia. A French Vanilla panel lists 22 g of protein in about 100 calories per 27.2 g scoop, with 2 g of carbohydrate and no fat, per the label at the time of writing; some flavors run slightly higher. It is Labdoor-tested per the brand but not NSF Certified for Sport, and costs roughly $2.50 per 25 g of protein at typical prices.

**Bottom line:** A clean, well-sourced isolate for recreational lifters who want natural sweeteners and will pay for them.

**Pros:**

- 22 g of protein in about 100 calories
- Irish grass-fed whey isolate with stevia, no sucralose
- Money-back guarantee with no return required, per Legion

**Cons:**

- No NSF Certified for Sport or Informed Sport certification
- Roughly $2.50 per 25 g of protein
- Some buyers report clumping in a shaker

### 2. Legion Plant+ Vegan Protein

**Award:** Best Vegan | **Type:** Pea and brown rice protein blend

- **Protein per serving:** 24 g (label)
- **Calories:** About 130-140 (by flavor)
- **Third-party testing:** Labdoor-certified brand (per Legion)
- **Best for:** Vegans and dairy-free lifters

Plant+ pairs PURIS pea protein with organic brown rice protein for 24 g of protein in about 130 to 140 calories per serving, per Legion at the time of writing, which is a full leucine-matched dose for most adults. It is sweetened with stevia and monk fruit or allulose depending on flavor. Expect roughly $2.60 per 25 g of protein at the brand's list price.

**Bottom line:** A strong-dose vegan powder for recreational lifters who want Legion's clean-label approach.

**Pros:**

- 24 g of protein per serving, high for a plant powder
- Complementary pea and rice blend with glyphosate-free certified peas, per Legion
- No artificial sweeteners

**Cons:**

- Not certified for sport
- Mid-premium cost per 25 g of protein

[Check price on Amazon](https://www.amazon.com/dp/B0GH2YR755?tag=sktiger-20&linkCode=ll1)

### 3. Legion Whey Protein (Concentrate)

**Award:** Budget Pick | **Type:** Whey protein concentrate

- **Protein per serving:** 20 g (brand)
- **Calories:** About 120
- **Third-party testing:** Labdoor-certified brand (per Legion)
- **Best for:** Legion fans on a budget

Legion's cheaper whey uses Avonlac 282 whey protein concentrate from cows never treated with rBST, according to the brand, for 20 g of protein in about 120 calories per serving. It keeps the house stevia-family sweeteners. At typical retail prices it lands around $2 per 25 g of protein, the lowest in the Legion range but still above mainstream blends.

**Bottom line:** The way into Legion on a smaller budget, if you tolerate concentrate well.

**Pros:**

- Lowest cost per gram in the Legion range
- rBST-free concentrate with natural sweeteners
- Same brand testing and guarantee as Whey+

**Cons:**

- Only 20 g of protein per serving
- More lactose than an isolate
- Still pricier than big-brand whey blends

[Check price on Amazon](https://www.amazon.com/dp/B0F7JC4QYP?tag=sktiger-20&linkCode=ll1)

### 4. Legion Casein+ Micellar Casein

**Award:** Bedtime Protein | **Type:** Micellar casein

- **Protein per serving:** 21 g (label panel)
- **Calories:** About 100
- **Third-party testing:** Labdoor-certified brand (per Legion)
- **Best for:** Evening protein, clean-label buyers

Casein+ is micellar casein from Irish grass-fed milk, sweetened with Reb M and including a little MCT powder. A Dutch Chocolate panel lists 21 g of protein in 100 calories per 28 g scoop at the time of writing, alongside a line for 25 g of micellar casein ingredient, so the true protein dose is lower than the 25 g some sources quote. At about $3.30 per 25 g of protein it is expensive casein.

**Bottom line:** Clean, but buy it only if Irish grass-fed casein matters more to you than dose or price.

**Pros:**

- Grass-fed Irish micellar casein with no artificial sweeteners
- Slow-digesting protein suited to evenings
- About 100 calories per scoop

**Cons:**

- 21 g of protein on the supplement panel, not 25 g
- Roughly $3.30 per 25 g of protein

[Check price on Amazon](https://www.amazon.com/dp/B07HJHX764?tag=sktiger-20&linkCode=ll1)

### 5. Transparent Labs 100% Grass-Fed Whey Protein Isolate

**Award:** Alternative: Better Value | **Type:** Grass-fed whey protein isolate

- **Protein per serving:** About 28 g (label)
- **Calories:** About 120 (by flavor)
- **Third-party testing:** Informed Choice (per brand)
- **Best for:** Clean isolate, more protein per dollar

The same clean-label idea as Whey+ with a bigger dose: about 28 g of protein per scoop from American grass-fed whey isolate, stevia sweetening, and Informed Choice certification according to Transparent Labs, which also publishes batch lab results. That brings cost per 25 g of protein to roughly $2.10 at list price, a little under Legion Whey+.

**Bottom line:** For most Legion shoppers, the better-value clean isolate.

**Pros:**

- About 28 g of protein per scoop
- Informed Choice certified, per the brand
- Batch lab results published

**Cons:**

- Large scoop means fewer servings per tub
- Not NSF Certified for Sport

[Check price on Amazon](https://www.amazon.com/dp/B0CQ32D39X?tag=sktiger-20&linkCode=ll1)

### 6. Optimum Nutrition Gold Standard 100% Whey

**Award:** Alternative: Budget | **Type:** Whey isolate and concentrate blend

- **Protein per serving:** About 24 g (varies by flavor)
- **Calories:** About 120
- **Third-party testing:** Informed Choice (confirm flavor)
- **Best for:** Budget buyers

If cost per gram matters more than the sweetener, Gold Standard delivers about 24 g of protein per scoop for roughly 120 calories, per the label at the time of writing, at a fraction of Legion's cost per 25 g. Optimum Nutrition states it is Informed Choice certified. Most flavors use artificial sweeteners, which is the trade-off.

**Bottom line:** The value benchmark Legion is priced against; buy it if natural sweeteners are not a priority.

**Pros:**

- About 24 g of protein per scoop
- Much lower cost per 25 g of protein
- Very wide flavor range and availability

**Cons:**

- Most flavors use sucralose
- Blend includes concentrate, so a little more lactose

[Check price on Amazon](https://www.amazon.com/dp/B000GISTZ4?tag=sktiger-20&linkCode=ll1)

## 4. The Whey+ Label, Line by Line

A French Vanilla supplement-facts panel at a large retailer lists a 27.2 g scoop, 22 g of protein, 100 calories, 2 g of carbohydrate, 1 g of sugar with no added sugar, and zero fat, with about 30 servings in a 1.8 lb tub, at the time of writing. That is roughly 81 percent protein by weight, which is normal for a flavored isolate. Other flavors run slightly heavier per scoop; Legion and some retailers describe the protein as 22 to 23 g depending on flavor.

The ingredient list is short: whey protein isolate, natural flavors, xanthan gum, sunflower lecithin, salt and stevia. The same panel also lists a small amount of maltodextrin, about 1 g, and a stevia extract carried on dextrin. Neither matters nutritionally, but buyers who expect a pure isolate with nothing added should know they are there.

Twenty-two grams of whey isolate supplies roughly 2.2 to 2.4 g of leucine, since whey runs about 10 to 11 percent leucine. That clears the threshold usually cited for a full muscle-building response in a single serving for most adults. In other words, one scoop of Whey+ does the job; you do not need a scoop and a half as you might with a 20 g isolate.

| Label item | Legion Whey+ | Typical mainstream whey |
| --- | --- | --- |
| Protein per scoop | 22 g | 24-25 g |
| Calories | About 100 | About 120 |
| Protein source | Irish grass-fed whey isolate | Whey concentrate and isolate blend |
| Sweetener | Stevia | Often sucralose |
| Testing | Labdoor-certified brand (per Legion) | Varies |

Buyer feedback on Whey+ is mostly positive about flavor, with the dessert-style options such as Cinnamon Cereal and Chocolate Peanut Butter drawing the most praise. The recurring complaint is mixing: some reviewers describe clumping in a shaker bottle, which a blender or a shaker with a whisk ball usually fixes. That is buyer feedback, not something we tested.

## 5. Labdoor Testing vs NSF Certification

Legion's pages describe the brand as independently certified by Labdoor, a company that buys supplements and tests them for label accuracy and contaminants, and say its products are made in NSF-certified, FDA-inspected facilities. Both statements are worth something. Neither is the same as a product sport certification.

A facility that is NSF certified for good manufacturing practice has passed audits of its processes. That is a baseline for any reputable supplement factory. It does not mean the specific Legion product has been tested for substances banned in sport. NSF Certified for Sport and Informed Sport are separate programs that test finished product lots for banned substances and are what anti-doping guidance tells athletes to look for.

> **The Rule**
>
> **Certified facility is not a certified product.**
>
> If you compete in a drug-tested sport, search the exact product in the NSF Certified for Sport or Informed Sport databases. If it is not listed, it is not certified for your purposes, no matter what the facility holds.

For a recreational lifter, Labdoor testing plus certificates of analysis covers the most important question, which is whether the protein on the label is in the tub. Legion publishes certificates of analysis on its product pages, which is better than many brands. It simply does not give you the banned-substance assurance that Momentous or Thorne provide.

Some retailer listings for Legion proteins also carry a California Proposition 65 warning about lead. That warning is a disclosure triggered at a very low threshold and appears on many cocoa-flavored and plant-based powders; it is not proof of an unsafe dose. If heavy metals concern you, the brand's certificates of analysis are the place to look, and our [protein powder safety guide](https://www.best-proteinpowder.com/is-protein-powder-safe/) explains what the numbers mean.

## 6. Casein+: Read the Supplement Panel

Casein+ is micellar casein from Irish grass-fed milk, sweetened with Reb M, a purified stevia compound, and including a small amount of MCT powder. Micellar casein digests slowly, which is why people take it before bed. On paper, it is a well-built product with a clean label.

The number to watch is protein per scoop. A Dutch Chocolate supplement-facts panel at a major retailer lists a 28 g scoop with 100 calories and **21 g of protein**, alongside a line reading 25 g of micellar casein protein, at the time of writing. The 25 g figure is the weight of the casein ingredient; the 21 g figure is the protein it actually provides. Some reviews and parts of Legion's own page quote 25 or 26 g, which overstates the dose.

At around $70 for roughly 25 servings, that works out to about $3.30 per 25 g of protein, which is expensive for casein. Mainstream micellar caseins with 24 g of protein per scoop typically cost much less, and Legion's own comparison table on the Casein+ page lists competitors at about $1.30 to $1.45 per serving.

If you want casein specifically from grass-fed Irish milk with no artificial sweetener, Casein+ is one of very few options, and it is a fine product. If you just want a slow protein before bed, compare it with the picks in our [best casein protein powder](https://www.best-proteinpowder.com/best-casein-protein-powder/) guide, where larger doses cost less per gram. Research on bedtime casein often uses 30 to 40 g, so with Casein+ you would need close to two scoops.

## 7. Plant+ and the Whey Concentrate

### Plant+

Plant+ combines PURIS pea protein with organic brown rice protein, which Legion lists as 17.6 g and 6.4 g respectively, for 24 g of protein per serving in about 130 to 140 calories depending on flavor. Legion says the peas are grown in North America and certified glyphosate-free. Sweetening comes from stevia, with monk fruit and allulose in some flavors.

That is a strong plant dose: 24 g of pea and rice protein supplies enough leucine for most adults in one serving, which many 20 g plant powders do not. At about $50 for 20 servings direct, Plant+ costs roughly $2.60 per 25 g of protein, mid-premium for a vegan powder. Like Whey+, it is Labdoor-tested per Legion but not NSF Certified for Sport. Our [best plant-based protein powder](https://www.best-proteinpowder.com/best-plant-based-protein-powder/) guide has certified and cheaper alternatives.

### Whey Protein (Concentrate)

Legion's newer, cheaper whey uses Avonlac 282 whey protein concentrate from cows never treated with rBST, according to the brand, and delivers 20 g of protein in about 120 calories per serving. Sweetening follows the house formula of stevia-family sweeteners and natural flavors.

Concentrate carries a little more lactose, fat and carbohydrate than isolate, which matters only if dairy sugar upsets your stomach. At around $45 per tub at retail, it lands at roughly $2 per 25 g of protein, though serving counts vary by flavor. That makes it Legion's value option, but it is still more expensive than mainstream whey blends with bigger scoops. Choose it if you want the Legion label and sweetener system for less money; otherwise a big-brand whey costs less.

## 8. Cost per 25 g of Protein

Scoop sizes in the Legion range run from 20 g to 24 g of protein, so price per tub tells you little. The fair comparison is cost per 25 g of protein. These are approximate figures at typical prices at the time of writing; Legion runs frequent sales and offers discounts for bundles and subscriptions, which can cut the cost by a fifth or more.

| Product | Protein per serving | Approx. cost per 25 g |
| --- | --- | --- |
| Legion Whey+ | 22 g | About $2.50 |
| Legion Plant+ | 24 g | About $2.60 |
| Legion Whey (concentrate) | 20 g | About $2 |
| Legion Casein+ | 21 g | About $3.30 |
| Transparent Labs Grass-Fed Isolate | 28 g | About $2.10 |
| Optimum Nutrition Gold Standard | 24 g | Often $1.40-1.60 |

Two things stand out. First, Whey+ is not the cheapest clean isolate. Transparent Labs puts 28 g of protein in a scoop and costs slightly less per 25 g at list price, with an Informed Choice certification the brand states on its page. Second, Casein+ is the worst value in the range, because its real protein figure is lower than the headline.

Legion's own comparison tables, which list Optimum Nutrition Gold Standard at about $1.38 per serving, make the budget gap clear. If cost per gram is your main concern, a mainstream whey wins easily. If a stevia-only label and Irish grass-fed sourcing matter to you, Whey+ on sale or in a bundle is a reasonable premium.

For a lifter taking one shake a day, the difference between Whey+ and a budget whey is roughly $25 to $30 a month at full price. Use our [protein needs guide](https://www.best-proteinpowder.com/how-much-protein-do-i-need/) to work out whether you need one shake or two before deciding how much the premium is worth.

## 9. Legion vs Transparent Labs, Momentous and Optimum Nutrition

**Transparent Labs Grass-Fed Whey Protein Isolate** is the closest match in philosophy: grass-fed whey, stevia sweetening, no artificial colors, published lab results. It delivers about 28 g of protein per scoop versus 22 g for Whey+, and Transparent Labs states that it carries Informed Choice certification. For most buyers choosing between the two, Transparent Labs is the better value. Our [Transparent Labs review](https://www.best-proteinpowder.com/transparent-labs-protein-powder-review/) covers the range.

**Momentous Whey Protein Isolate** is the pick for drug-tested athletes. It is NSF Certified for Sport, with 20 g of protein per scoop, and costs more per gram than Whey+. If you need a sport certification, Momentous or Thorne beat Legion; if you do not, Legion gives you more protein per scoop for less. See our [Momentous review](https://www.best-proteinpowder.com/momentous-protein-powder-review/).

**Optimum Nutrition Gold Standard 100% Whey** is the budget benchmark: about 24 g of protein per scoop from a whey blend led by isolate, with Informed Choice certification according to the brand, at a fraction of Legion's cost per gram. It uses artificial sweeteners in most flavors, which is the main reason Legion buyers avoid it. Read our [Optimum Nutrition review](https://www.best-proteinpowder.com/optimum-nutrition-protein-powder-review/) for the full picture.

| Powder | Protein per scoop | Sweetener | Testing |
| --- | --- | --- | --- |
| Legion Whey+ | 22 g | Stevia | Labdoor-certified brand (per Legion) |
| Transparent Labs Isolate | About 28 g | Stevia | Informed Choice (per brand) |
| Momentous Isolate | 20 g | Monk fruit and stevia | NSF Certified for Sport |
| ON Gold Standard | About 24 g | Mostly sucralose | Informed Choice (per brand) |

Put simply, Legion sits in a middle position: cleaner than the mainstream giants, less certified than the sport-focused brands, and slightly outgunned on value by Transparent Labs. It is a good product that is rarely the single best choice for any one buyer.

## 10. Who Should Skip Legion

**Drug-tested athletes.** Labdoor testing and NSF-registered facilities do not equal NSF Certified for Sport or Informed Sport product certification. Choose a product that appears in those databases instead, such as Momentous or Thorne.

**Budget buyers.** At about $2.50 per 25 g of protein for Whey+, Legion costs far more than mainstream wheys that deliver as much or more protein per scoop. If you are fine with sucralose, the savings are substantial. Our [best whey protein powder](https://www.best-proteinpowder.com/best-whey-protein-powder/) guide lists the value leaders.

**Anyone who dislikes stevia.** Every Legion protein uses stevia or a stevia-derived sweetener. If its aftertaste bothers you, no Legion flavor will fix that. The no-return guarantee makes a trial low-risk, but go in knowing the sweetener system.

**Casein buyers chasing a big dose.** With 21 g of protein per scoop on the supplement panel and a high price, Casein+ is an expensive way to get bedtime protein. A mainstream micellar casein delivers more per scoop for less.

**People with medical conditions.** If you have kidney disease, are pregnant, have a milk allergy or take medication, check with your doctor or a registered dietitian before adding concentrated protein. Nothing here is medical advice.

## 11. Common Mistakes to Avoid

### Reading the casein line instead of the protein line

Casein+ panels list 25 g of micellar casein but 21 g of protein. The ingredient weight is not the protein dose. Always read the Protein row of the supplement-facts panel when comparing powders, especially when a review or ad quotes a rounder, bigger number. The gap here is about 4 g per scoop.

### Treating an NSF-certified facility as a certified product

Legion says its products are made in NSF-certified facilities. That is a manufacturing audit, not banned-substance testing of the product. Drug-tested athletes need the exact product listed in the NSF Certified for Sport or Informed Sport database, which Legion's proteins are not at the time of writing.

### Paying full price

Legion runs frequent sales, bundle discounts and subscription pricing on its own site, and retailer prices vary widely. Buying a single tub at full list price can cost a fifth more than a sale or multi-pack. Compare the brand site, Amazon and large retailers before ordering, and stock up only when the discount is real.

### Assuming natural sweeteners taste neutral

Stevia has a distinctive aftertaste that some people notice strongly. If you have disliked stevia-sweetened drinks before, try a small size or a single flavor first rather than a multi-tub bundle, and use the guarantee if it does not work for you. Mixing it into milk or a smoothie often softens the aftertaste.

### Ignoring cheaper isolates with bigger scoops

Whey+ is good, but Transparent Labs delivers about 28 g of protein per scoop with a similar clean label and slightly lower cost per 25 g. Compare cost per gram of protein across clean-label isolates before settling on the one with the best marketing or the most familiar name.

## 12. Frequently Asked Questions

### Is Legion protein powder good?

Yes, for recreational lifters who want natural sweeteners. Legion Whey+ provides 22 g of Irish grass-fed whey isolate protein in about 100 calories with stevia instead of sucralose. It is not NSF Certified for Sport, and at about $2.50 per 25 g of protein it costs more than mainstream wheys and slightly more than Transparent Labs.

### How much protein is in Legion Whey+?

A French Vanilla supplement-facts panel lists 22 g of protein per 27.2 g scoop, with about 100 calories, 2 g of carbohydrate and no fat, at the time of writing. Legion and some retailers describe 22 to 23 g depending on flavor, so check the panel on the tub you buy.

### Is Legion Whey+ third-party tested?

Legion says its products are independently certified by Labdoor, publishes certificates of analysis, and states they are made in NSF-certified facilities. Whey+ is not listed as NSF Certified for Sport or Informed Sport at the time of writing, so drug-tested athletes should choose a product that appears in those databases.

### How much protein is in Legion Casein+?

Retailer supplement-facts panels list 21 g of protein per scoop of about 27 to 28 g, with roughly 100 calories, at the time of writing. A separate line lists 25 g of micellar casein, which is the ingredient weight rather than the protein dose, so expect about 21 g per scoop.

### What sweetener does Legion use?

Legion uses stevia across its proteins. Whey+ lists stevia leaf extract and a stevia extract on dextrin, Casein+ uses Reb M, and Plant+ and the whey concentrate add monk fruit or allulose in some flavors per Legion. None of the protein powders use sucralose or acesulfame potassium, per the labels at the time of writing.

### Is Legion protein sold on Amazon?

Yes. Legion's proteins are sold on Amazon as well as on Legion's own site and at retailers such as Vitacost, iHerb, GNC and Kohl's. Prices and stock vary by channel and flavor, and Legion's own site often has bundle discounts, so compare before buying a multi-tub order.

### Is Legion Whey+ better than Optimum Nutrition Gold Standard?

It has a cleaner label, with Irish grass-fed whey isolate and stevia instead of sucralose, but Gold Standard gives slightly more protein per scoop for far less money and states Informed Choice certification. Choose Legion if natural sweeteners matter to you; choose Gold Standard if cost per gram matters more.

## The Bottom Line

Legion makes clean, honestly sweetened protein with well-chosen sources, and Whey+ is a genuinely good grass-fed isolate: 22 g of protein in about 100 calories, stevia instead of sucralose, and a guarantee that removes most of the risk of trying it.
