# Transparent Labs Protein Review > Transparent Labs protein reviewed by label: 28 g grass-fed whey isolate, Informed Choice status, the rest of the range, and what it really costs per 25 g. - **URL**: https://www.best-proteinpowder.com/transparent-labs-protein-powder-review/ - **Updated**: 2026-11-02 - **Author**: [Best Protein Powder Editorial Team](https://www.best-proteinpowder.com/authors/editorial-team/) - **Publisher**: [Best Protein Powder](https://www.best-proteinpowder.com/) --- A certified, grass-fed whey isolate with no artificial sweeteners and a premium price. Here is whether it earns that price, and which tub in the range to buy. **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/) Transparent Labs makes one of the cleanest certified whey isolates on the market. It is also more expensive per gram than most of the competition. The isolate is worth it if certification and clean labeling are your priorities. Most of the rest of the range is optional. ## Our Top Picks | Award | Product | Why | | --- | --- | --- | | Best Overall | [Transparent Labs 100% Grass-Fed Whey Protein Isolate](https://www.best-proteinpowder.com/transparent-labs-protein-powder-review/#transparent-labs-grass-fed-whey-protein-isolate) | One of the cleanest certified isolates you can buy.

The Short Verdict on Transparent Labs Transparent Labs has built its reputation on one product, and that product deserves it. The **100% Grass-Fed Whey Protein Isolate** gives 28 g of protein in a scoop of about 32 g, per the brand. It has no artificial sweeteners, dyes or fillers, comes in more than a dozen flavors, and carries Informed Choice and Informed Protein certification. Few whey isolates tick all of those boxes at once. The catch is price. At list price on the brand's site, a 2 lb tub of 30 scoops is about $65, which comes to roughly $1.95 per 25 g of protein. The 4 lb tub brings that down to about $1.65. That is more than most mainstream isolates, and you are mostly paying for grass-fed sourcing and certification, not for more protein in the scoop. Whether that is worth it depends on how much those two things matter to you. The rest of the range is more mixed. The casein is a good, clean bedtime protein. The Organic Vegan blend is fine but faces stronger plant-only competitors. The beef protein isolate is a niche product for people who avoid dairy. We rank all of them below on the label, certification and cost per 25 g of protein. We have not tasted any of them, so where taste comes up we are reporting buyer feedback. If you are comparing isolates more broadly, our [best whey protein isolates](https://www.best-proteinpowder.com/best-whey-protein-isolate/) roundup puts Transparent Labs next to the other leading options on the same criteria. This page answers a narrower question: is Transparent Labs protein any good, which tub should you buy, and who should spend their money elsewhere. ## 2. The Transparent Labs Protein Range Transparent Labs is a Utah-based supplement company, and protein is one part of a much larger catalog that includes pre-workouts, creatine and vitamins. Its protein shelf currently covers the whey isolate, a micellar casein, an Organic Vegan rice and pea blend, a single-source organic pea protein isolate, a grass-fed beef protein isolate, a mass gainer, collagen, a protein coffee and a ready-to-drink protein shake sold in the US only. | Product | Protein per scoop | Calories per scoop | Scoops per tub | | --- | --- | --- | --- | | Grass-Fed Whey Protein Isolate | 28 g | About 120-150 | 30 (2 lb) | | Grass-Fed Casein Protein | 25 g | About 120 | 30 | | Organic Vegan Plant-Based Protein | 24 g | About 130-150 | 30 | | Pea Protein Isolate | 28 g | Check label | Check label | | Grass-Fed Beef Protein Isolate | 25 g | Check label | Check label | | Mass Gainer | 26-27 g | About 365-375 | 30 (two per serving) | | Grass-Fed Collagen | 20 g | About 90 | 30 | Those figures come from the brand's own product pages and comparison chart at the time of writing, and they vary a little by flavor. The mass gainer is the one to read carefully. A full serving is two scoops, which the brand lists as 750 calories and more than 50 g of protein from grass-fed whey concentrate. It also contains 3 g of creatine monohydrate and more than 100 g of carbohydrate. If you are bulking, our [weight gain protein guide](https://www.best-proteinpowder.com/best-protein-powder-for-weight-gain/) compares it with other gainers. The Pea Protein Isolate deserves a mention because the brand describes it as USDA-certified organic, with 28 g of protein per scoop of about 38 g, sweetened with stevia. That makes it a better plant option than the Organic Vegan blend for anyone who wants maximum protein per scoop, though its flavor range is just chocolate and vanilla. Collagen is not a complete protein and should not be counted the same way as whey toward a muscle-building target. ## 3. The Transparent Labs Powders Worth Considering Four Transparent Labs proteins, flagship first, plus one cheaper certified alternative. Figures are per the brand's pages and labels at the time of writing and vary by flavor. We have not tasted these products, and any taste notes are buyer feedback. ### 1. Transparent Labs 100% Grass-Fed Whey Protein Isolate **Award:** Best Overall | **Type:** Grass-fed whey protein isolate - **Protein / serving:** 28 g (brand, varies slightly by flavor) - **Calories:** About 120-150 - **Third-party testing:** Informed Choice + Informed Protein - **Best for:** Most buyers, lactose-sensitive lifters This is the product the brand is known for. Per Transparent Labs at the time of writing, a scoop of about 32 g gives 28 g of protein, roughly 120-150 calories depending on flavor, 0-3 g of carbs and about 1 g of fat. The whey comes from grass-fed American dairy cattle raised without growth hormones. It has no artificial sweeteners or dyes and is Informed Choice and Informed Protein certified. It comes in more than a dozen flavors plus unflavored. **Bottom line:** One of the cleanest certified isolates you can buy. You pay a premium for the grass-fed sourcing. **Pros:** - 28 g of protein per scoop, about 87% protein by weight, per the brand - Informed Choice and Informed Protein certified, per the brand - No artificial sweeteners, dyes or fillers - Wide flavor range, including an unflavored version **Cons:** - About $1.65-1.95 per 25 g of protein at list price, more than mainstream isolates - Peanut-based flavors contain real peanuts, so allergy sufferers need to pick carefully [Check price on Amazon](https://www.amazon.com/dp/B0CQ32D39X?tag=sktiger-20) ### 2. Transparent Labs Grass-Fed Casein Protein **Award:** Best Before Bed | **Type:** Instantized micellar casein, grass-fed - **Protein / serving:** 25 g (brand) - **Calories:** About 120 - **Third-party testing:** Batch-tested per brand (check COA) - **Best for:** Bedtime shakes, puddings Transparent Labs' casein gives 25 g of instantized micellar casein from grass-fed cattle per scoop, with about 120 calories and 4 g of carbs, per the brand at the time of writing. It is naturally flavored and sweetened with stevia, with no added sugar. Micellar casein digests slowly, which is why it is sold as a bedtime protein, and it makes a thick shake or a pudding when mixed with less liquid. **Bottom line:** A clean, grass-fed casein for night-time shakes. Buy it only if you want casein specifically. **Pros:** - 25 g of slow-digesting micellar casein per scoop - Stevia-sweetened, with no added sugar - Grass-fed sourcing, matching the whey isolate **Cons:** - Only two flavors - About $2 per 25 g of protein at list price [Check price on Amazon](https://www.amazon.com/s?k=Transparent%20Labs%20Grass-Fed%20Casein%20Protein&tag=sktiger-20) ### 3. Transparent Labs Organic Vegan Plant-Based Protein **Award:** Best Plant-Based | **Type:** Organic rice and pea protein blend - **Protein / serving:** 24 g (brand) - **Calories:** About 130-150 - **Third-party testing:** Batch-tested per brand (check COA) - **Best for:** Vegans already using TL The brand's main plant option blends organic rice protein with organic pea protein concentrate and isolate. Per Transparent Labs at the time of writing, it gives 24 g of protein in roughly 130-150 calories and 3-7 g of carbs per scoop, with 30 scoops per tub. It is soy-free and has no added sugar. Buyer reviews on the brand's site mention a strong stevia taste and some graininess, which is common with rice and pea blends. **Bottom line:** A solid vegan option from the brand, but plant-only buyers have cheaper certified choices elsewhere. **Pros:** - Rice and pea blend gives a complete amino acid profile - Organic protein sources, no soy and no added sugar - Lowest list price per tub in the Transparent Labs protein range **Cons:** - 24 g of protein per scoop, less than the whey isolate - Some buyers report a strong stevia taste and grainy texture [Check price on Amazon](https://www.amazon.com/s?k=Transparent%20Labs%20Organic%20Vegan%20Plant-Based%20Protein&tag=sktiger-20) ### 4. Transparent Labs Grass-Fed Beef Protein Isolate **Award:** Best Dairy-Free Animal Protein | **Type:** Hydrolyzed grass-fed beef protein isolate - **Protein / serving:** 25 g (brand) - **Calories:** Check label - **Third-party testing:** COA published per brand - **Best for:** Dairy-free, paleo diets For people who cannot tolerate dairy but do not want plant protein, Transparent Labs sells a beef protein isolate. The brand says each scoop gives 25 g of hydrolyzed grass-fed beef protein, more than 95% protein, with no dairy or lactose, sweetened with stevia. It is naturally rich in glycine, proline and hydroxyproline, the amino acids typical of collagen. That makes it a different amino acid profile from whey rather than a like-for-like swap. **Bottom line:** Worth it only if dairy is off the table and you want an animal protein. Everyone else should buy the whey isolate. **Pros:** - Dairy-free and lactose-free animal protein - 25 g of protein per scoop, per the brand - Three flavors, sweetened with stevia **Cons:** - Collagen-type amino acid profile, likely lower in leucine per gram than whey - Premium price for a niche product [Check price on Amazon](https://www.amazon.com/dp/B0FQCPCQLS?tag=sktiger-20&linkCode=ll1) ### 5. Ascent Whey Protein **Award:** Alternative: Cheaper Informed Sport Whey | **Type:** Whey isolate blend with whey concentrate - **Protein / serving:** 25 g (label, chocolate) - **Calories:** About 120 - **Third-party testing:** Informed Sport - **Best for:** Budget-minded tested athletes If Transparent Labs' price is the sticking point, Ascent is the closest certified alternative. The chocolate label lists 25 g of protein and 120 calories in a 33 g scoop. The protein is a whey isolate blend, including native whey isolate, plus some whey concentrate, sweetened with stevia. It is Informed Sport certified, per Ascent. It is not a pure isolate, so very lactose-sensitive buyers should stay with Transparent Labs. **Bottom line:** A certified, cleanly sweetened whey for less money, if you do not need a pure isolate. **Pros:** - Informed Sport certified, per Ascent - Lower list cost per 25 g than Transparent Labs in the 4 lb bag - Stevia-sweetened, with no artificial flavors **Cons:** - Contains some whey concentrate, so more lactose than a pure isolate - Soy lecithin, so not soy-free [Check price on Amazon](https://www.amazon.com/dp/B01N9V32X2?tag=sktiger-20&linkCode=ll1) ## 4. What Is in the Whey Isolate The ingredient list on the flagship is short. Unflavored is just whey protein isolate. Flavored versions add natural flavors, a natural sweetener and, in some flavors, ingredients like cocoa or peanut. There is no sucralose, acesulfame potassium, aspartame, artificial color or filler. That is the core of the brand's pitch, and the label backs it up. Grass-fed is the other headline. Transparent Labs says its whey comes from grass-fed American dairy cattle raised without growth hormones, growth factors or anabolic steroids. The brand's page cites research suggesting grass-fed milk is higher in some fatty acids and bioactive compounds. Be realistic about what survives into an isolate, though. Isolation strips out almost all of the fat, so the fatty acid differences mostly do not reach the scoop. What you are mainly buying is a sourcing standard. The protein density is the more useful number. At 28 g of protein per 32 g scoop, about 87% of the powder by weight is protein, per the brand. That is high for a flavored product and tells you there is little room for fillers. Fat is about 1 g per scoop, and carbs range from 0 to 3 g depending on flavor. Transparent Labs describes it as virtually lactose-free, which is typical of a true isolate. On allergens, the brand says it tests for gluten and the eight major allergens, runs an allergen segregation program, and holds NSF certification at the facility level. That is a statement about the facility, not a product certification. The peanut-based flavors contain real peanuts. If you have a nut allergy, choose a flavor that has no peanut ingredients, and check the label, since the brand also processes coconut and peanut products in the same facility. > **WHAT IS AN ISOLATE?** > > **Isolate vs concentrate, in one line** > > Whey isolate is filtered further than concentrate to remove most of the lactose and fat, which gives more protein per gram and fewer digestive complaints for lactose-sensitive people. It costs more to make. Our guide to [whey vs whey isolate](https://www.best-proteinpowder.com/whey-vs-whey-isolate/) covers when the upgrade is worth paying for. ## 5. Certifications and Third-Party Testing Transparent Labs leans heavily on testing, and it is one of the better-documented brands in the category. The whey isolate is **Informed Choice** certified, a program that screens for substances banned in sport, and **Informed Protein** certified, which checks that the protein content on the label matches what is in the tub. The mass gainer also carries Informed Choice certification, per the brand. The brand also says every batch is tested by a third-party lab for purity and potency, and it publishes those certificates of analysis on its website. That is more than most brands do. Reading a certificate takes a little practice, but the basic checks are simple: the protein figure should match the label, and heavy metal results should sit well below the limits listed on the report. Transparent Labs also cites a Labdoor score of 98 out of 100 for the whey isolate. Labdoor is an independent testing and ranking site. Its scores are useful context, but they are a snapshot of particular batches, not an ongoing certification, so give them less weight than Informed Choice. For tested athletes, the Informed Choice listing is what matters. Search the product and flavor on the certifier's site before you rely on it. Not every product in the range carries the same certification. The brand's pages for the casein, the Organic Vegan blend and the beef isolate do not mention Informed Choice in the text we reviewed. If certification is your reason for choosing Transparent Labs, buy the whey isolate or the mass gainer, and check the rest one by one. Our guide on [protein powder safety](https://www.best-proteinpowder.com/is-protein-powder-safe/) explains what each type of testing covers. ## 6. Cost per 25 g of Protein Transparent Labs prices are firm compared with most of the market. The table uses brand-site list prices at the time of writing. Subscribe and save discounts and retailer sales can bring them down, so treat these as approximate upper figures. We use cost per 25 g of protein because it is the only fair way to compare tubs with different scoop sizes. | Product and size | List price (approx.) | Cost per 25 g protein (approx.) | | --- | --- | --- | | Whey Isolate, 2 lb (30 scoops) | About $65 | About $1.95 | | Whey Isolate, 4 lb | About $110 | About $1.65 | | Grass-Fed Casein (30 scoops) | About $60 | About $2.00 | | Organic Vegan (30 scoops) | About $50 | About $1.75 | | Ascent Whey, 4 lb (alternative) | About $90 | About $1.65 | The 4 lb whey isolate is clearly the best value in the range. If you already know you like a flavor, buying the 2 lb tub costs about 15% more per gram of protein for no benefit. The casein is the most expensive per gram, which is normal for casein across brands. The Organic Vegan blend's lower tub price is partly offset by its lower protein per scoop. In context, Transparent Labs is a premium isolate, but not an outlier. Several grass-fed and certified isolates sit in the same range, and mainstream isolates without grass-fed sourcing are often noticeably cheaper per gram. Our [Dymatize review](https://www.best-proteinpowder.com/dymatize-protein-powder-review/) covers one of the big mainstream isolates, and our [Thorne review](https://www.best-proteinpowder.com/thorne-protein-powder-review/) covers a premium NSF-certified one, for a sense of where the edges of the category sit. At one scoop a day, the 2 lb isolate costs about $65 a month at list price and the 4 lb tub about $55. That is a real line in a monthly budget. If the premium hurts, the Ascent alternative or a mainstream isolate will get you the same protein. If clean labeling and certification are what you value most, Transparent Labs is a reasonable place to spend. ## 7. Flavors, Taste and Mixing: What Buyers Report We have not tasted these products, so this is a summary of buyer feedback. The whey isolate has thousands of reviews on the brand's site with a high average score, and the recurring praise is that it mixes easily and is less sweet than mainstream isolates. That fits the label. Without sucralose, flavors lean more natural and less candy-like, which some buyers love and others find flat. Flavor variety is a real strength. The comparison chart lists 22 flavors for the whey isolate, from chocolate and vanilla to dessert-style options like cinnamon French toast, chocolate chip cookie dough and blueberry pancakes, plus unflavored. Unflavored is the version to buy for cooking and smoothies. It is just whey isolate, and it disappears into oats, yogurt and pancakes. Our [unflavored protein guide](https://www.best-proteinpowder.com/best-unflavored-protein-powder/) covers it alongside other plain options. The plant products get more mixed feedback. Reviews on the Organic Vegan page include praise for the clean ingredient list alongside complaints about strong stevia and a grainy texture, which is typical of rice and pea blends. Blending it with banana and nut butter, as several buyers describe doing, covers most of that. The casein mixes thicker than the whey, as all micellar casein does, which works in its favor for puddings. For the best result with the isolate, use 6-8 oz of cold water or milk in a shaker with a wire ball, as the brand suggests. Isolates froth if you blend them hard, so add them at the end of a smoothie and pulse briefly. With casein, start with less liquid than you think you need, then thin it out. ## 8. Transparent Labs vs Other Isolates Against **Ascent**, Transparent Labs wins on purity and loses on price. Ascent's whey is a blend of native whey isolate, regular whey isolate and some whey concentrate, at 25 g of protein per scoop, and it is Informed Sport certified. Transparent Labs is a pure isolate at 28 g. Very lactose-sensitive buyers should pick Transparent Labs. Everyone else may find Ascent's lower 4 lb price persuasive. Our [Ascent protein review](https://www.best-proteinpowder.com/ascent-protein-powder-review/) goes into detail. Against **Naked Nutrition**, the trade is flavor and certification against simplicity. Naked's unflavored grass-fed whey isolate has only two ingredients, whey isolate and sunflower lecithin, and 30 g of protein per serving, and it now comes in a handful of flavors too. Transparent Labs offers far more flavors and Informed certification. If you mostly blend your protein, the comparison in our [Naked Nutrition review](https://www.best-proteinpowder.com/naked-nutrition-protein-powder-review/) is worth a look. Against mainstream isolates like **Dymatize ISO100** and **Isopure**, Transparent Labs usually costs more. Those brands are often cheaper per gram and widely discounted, and many mainstream isolates sweeten with sucralose, so read the label on the flavor you want. If you have no objection to artificial sweeteners, they are perfectly good products and our [Isopure review](https://www.best-proteinpowder.com/isopure-protein-powder-review/) explains its lineup. If you want to avoid artificial sweeteners, Transparent Labs is one of the strongest options. Against other premium certified brands like **Momentous** and **Legion**, it comes down to flavor preference and price on the day. All three sell themselves as premium, clean-label, third-party-tested brands, so compare the label and certification of the exact flavor you want. Our [Momentous review](https://www.best-proteinpowder.com/momentous-protein-powder-review/) and [Legion review](https://www.best-proteinpowder.com/legion-protein-powder-review/) cover those. Transparent Labs offers the widest flavor range of the three. ## 9. Who Should Buy Transparent Labs, and Who Should Skip It **Buy the Grass-Fed Whey Protein Isolate** if you want a certified isolate with no artificial sweeteners, if you are lactose-sensitive and find concentrate blends bloat you, or if grass-fed sourcing matters to you. Buy the 4 lb tub once you have a flavor you like. It is the product that justifies the brand's reputation, and it is the one we would recommend first. **Buy the casein** if you specifically want slow-digesting protein before bed or a thick pudding-style snack, and you like having the same grass-fed standard as the whey. **Buy the beef isolate** only if you avoid dairy and do not want plant protein. **Buy the mass gainer** only if you genuinely struggle to eat enough. At 750 calories a serving, it is not a casual add-on. **Skip Transparent Labs** if you are on a tight budget. The same 25 g of protein is available for less from mainstream isolates and larger concentrate tubs. Skip the Organic Vegan blend if you are plant-only and want maximum protein per scoop, as the pea isolate or a dedicated plant brand will do better. Our [plant-based protein guide](https://www.best-proteinpowder.com/best-plant-based-protein-powder/) lists the alternatives. As with any protein powder, if you have kidney disease, are pregnant, or take medication, talk to your doctor or a registered dietitian before adding concentrated protein or a creatine-containing gainer to your diet. This review covers label facts and value. It is not medical advice. ## 10. How to Use It Well One scoop of the isolate, at 28 g of protein, is about the dose research suggests most adults need per meal to maximize muscle protein synthesis. Larger or older lifters may benefit from a little more. Most people do not need two scoops at once. Spread your intake through the day instead, and use our [protein needs guide](https://www.best-proteinpowder.com/how-much-protein-do-i-need/) to set a daily target before deciding how many shakes you need. Use the right product at the right time. The isolate digests quickly, so it suits mornings, post-workout and any time you want a light shake. The casein digests slowly and suits the evening or a long gap between meals. Combining both is not necessary for most people. Total daily protein matters far more than timing, as our guide on [when to take protein powder](https://www.best-proteinpowder.com/when-to-take-protein-powder/) explains. Cook with the unflavored isolate rather than the flavored ones. It works in pancakes, oats, yogurt and baked goods, though isolates can dry baked goods out, so add a little extra liquid or fat. Keep the tub sealed and dry. Use the included scoop, because scoop sizes differ between Transparent Labs products, and borrowing a scoop from another brand will throw your numbers off. If you are drug tested, keep a record of the batch number and check the Informed Choice listing whenever you rebuy. Certification applies to batches that were tested, and the brand's published certificates make that easy to check. That habit, not the brand name, is what protects a tested athlete. ## 11. Common Mistakes to Avoid ### Buying the 2 lb tub every month At list price, the 4 lb whey isolate costs roughly 15% less per gram of protein than the 2 lb tub. If you have found a flavor you like and use one scoop a day, the larger tub saves a meaningful amount over a year without any trade-off in what you are drinking. ### Assuming the whole range is certified The whey isolate and mass gainer carry Informed Choice certification, per the brand. The pages for the casein, Organic Vegan and beef isolate do not make the same claim. Tested athletes should look up the exact product and flavor in the certifier's database before relying on it. ### Treating the mass gainer as a protein shake A full serving of the mass gainer is two scoops, about 750 calories and more than 100 g of carbohydrate, per the brand. That is a meal and a half. If you only wanted more protein, it will add weight you did not plan for. Buy the isolate instead. ### Counting collagen toward your protein target Transparent Labs' collagen lists 20 g of protein per scoop, but collagen lacks tryptophan and is low in leucine, so it is not a complete protein. It does not build muscle the way whey does. Count it separately, or not at all, when you work out your daily target. ### Ignoring peanut flavors with an allergy Some flavors of the whey isolate contain real peanuts, and the facility processes coconut and peanut products alongside other runs, per the brand. If you have a nut allergy, check every flavor's allergen statement on the label and ask your allergist before choosing any shared-facility product. ## 12. Frequently Asked Questions ### Is Transparent Labs whey a true isolate? Yes. The flagship lists whey protein isolate as its protein source, with 28 g of protein in a scoop of about 32 g. That works out to about 87% protein by weight, per the brand. Transparent Labs describes it as virtually lactose-free, with about 1 g of fat and 0-3 g of carbs per scoop depending on flavor. ### Is Transparent Labs protein third-party tested? Yes. The whey isolate is Informed Choice and Informed Protein certified, and the brand says every batch is tested by a third-party lab, with certificates of analysis published on its website. Certification applies product by product, so check the specific product and flavor in the Informed Choice database if you are a tested athlete. ### What sweetener does Transparent Labs use? Transparent Labs uses no artificial sweeteners, according to the brand. Its casein, beef isolate, pea isolate and mass gainer are described as sweetened with stevia, and the flavored whey isolate is naturally sweetened. There is no sucralose, aspartame or acesulfame potassium, and an unflavored isolate with no sweetener at all is also sold. ### Is Transparent Labs worth the price? For the whey isolate, yes, if you value grass-fed sourcing, no artificial sweeteners and certification. At list price it works out to roughly $1.65-1.95 per 25 g of protein depending on tub size. If those features do not matter to you, mainstream isolates deliver the same protein for less, often with frequent discounts. ### Is Transparent Labs good for lactose intolerance? The whey isolate is filtered to remove most lactose, and the brand calls it virtually lactose-free. Many people with mild lactose intolerance tolerate isolates well. People with a milk protein allergy should avoid all whey. The beef isolate and plant proteins are dairy-free alternatives. Ask your doctor if you have a diagnosed allergy. ### Is Transparent Labs on Amazon? Yes. Transparent Labs whey isolate is sold on Amazon US, alongside the brand's own store. Check that the listing is sold by the brand or by Amazon itself, not a third-party reseller, to reduce the risk of old or counterfeit stock. Prices on Amazon and the brand site move independently, so compare cost per scoop on the day. ### Where is Transparent Labs based? Transparent Labs lists a shipping and returns address in American Fork, Utah, and it ships worldwide apart from a short list of excluded countries. It sells a broad catalog beyond protein, including pre-workouts, creatine and vitamins. Its protein range covers whey isolate, casein, plant, beef, collagen and a mass gainer. ## Related Whey Isolate Guides - [Best Whey Protein Isolate](https://www.best-proteinpowder.com/best-whey-protein-isolate/): Transparent Labs ranked against every leading isolate on label, testing and cost. - [Whey vs Whey Isolate](https://www.best-proteinpowder.com/whey-vs-whey-isolate/): When paying more for an isolate actually makes a difference. - [Ascent Protein Review](https://www.best-proteinpowder.com/ascent-protein-powder-review/): The cheaper, Informed Sport certified whey Transparent Labs buyers often compare. ## The Bottom Line Transparent Labs' grass-fed whey isolate is one of the best clean-label isolates you can buy. It has 28 g of protein per scoop, Informed Choice certification, no artificial sweeteners and a long list of flavors. The price is the only real knock, and the 4 lb tub softens it.
