Transparent Labs lives up to its name: every dose is printed on the label, there are no proprietary blends, and products are certified by Informed Choice and Informed Protein. It costs more than mass-market brands, but for label readers and tested athletes it is one of the most trustworthy options available.
What we like
- No proprietary blends; every ingredient and dose is disclosed
- Informed Choice and Informed Protein certification, plus extensive third-party lab testing
- No artificial sweeteners, colors or preservatives; sweetened with stevia
- Strong core products: Grass-Fed Whey Isolate, Creatine HMB and Bulk pre-workout
- 30-day satisfaction guarantee that covers opened products
Keep in mind
- Premium pricing compared with big-box sports brands
- Mostly sold online, with limited retail presence
- Popular flavors sell out from time to time
- Stevia-sweetened flavors are not to everyone's taste
Transparent Labs, based in American Fork, Utah, was built on a reaction against one of the sports supplement industry's oldest habits: hiding doses inside proprietary blends. Its labels list every active ingredient and its exact amount, its formulas avoid artificial sweeteners and colors, and its products are certified by third-party programs that test for banned substances.
The brand now covers protein, pre-workouts, creatine, recovery, vitamins, greens and sleep. We looked at which products are worth buying, what they contain, how pricing and policies compare, and who gets the most value from paying a little more.
Why label transparency matters
A proprietary blend lets a brand list ingredients without saying how much of each is included, so a product can name an effective compound but contain only a token amount. Transparent Labs prints full doses instead, which means you can compare its formulas directly with published research and with competitors.
The brand says its products are made in the US in cGMP-compliant facilities, and that it runs thousands of third-party lab tests for purity and potency. Products are certified by Informed Choice and Informed Protein, programs that screen for substances banned in sport and verify protein content. Sweetening is done with stevia rather than sucralose or aspartame.
The products that built the brand
Grass-Fed Whey Protein Isolate
About 28 grams of protein per serving with only one to two grams of carbohydrates and fat, made from the milk of grass-fed American cows and cold-processed. It comes in around 22 flavors, from classic chocolate and vanilla to options such as Cinnamon French Toast and Mocha.
Creatine HMB
Combines 5 grams of creatine monohydrate with 1.5 grams of HMB (beta-hydroxy beta-methylbutyrate), a leucine metabolite studied for muscle recovery. Available in flavored and unflavored versions.
Bulk and Lean pre-workouts
Bulk is the full-strength option, with about 6 grams of citrulline malate, 4 grams of beta-alanine and 180 mg of caffeine per serving. Lean targets training during fat loss, with no added sugar and ingredients such as acetyl-L-carnitine and L-theanine.
Beyond the gym
The range also includes intra-workout EAAs, Mass Gainer, Protein+ Bars, a ready-to-drink protein shake, a Multivitamin, Vitamin D3 + K2, Immune Support, Prebiotic Greens, Collagen Hydrolysate, a nootropic and a melatonin-free Sleep Aid with L-theanine and magnesium.

What to buy first
For most people, Grass-Fed Whey Protein Isolate is the best introduction: it is the brand's most popular product, mixes cleanly and suits people who are mildly sensitive to lactose better than concentrate-heavy blends. Pair it with Creatine HMB if strength and muscle are your goals; the Protein + Creatine Core Bundle packages both together.
Only add a pre-workout if you genuinely need one. If you do, try Bulk at half a serving first to judge your tolerance to the caffeine and the tingling sensation that beta-alanine commonly causes. Lean is better for evening sessions if you choose a lower-stimulant approach, but still check the caffeine content on the label.
Outside the gym staples, the daily-health products are worth a look if you prefer to keep everything under one brand. The Multivitamin and Vitamin D3 + K2 cover common gaps, Prebiotic Greens adds fiber and greens on busy days, and the melatonin-free Sleep Aid is an option for people who want to avoid hormones at bedtime. As always, ask whether you actually need each one before adding it.
A simple, effective starter stack for most lifters is just two products: a scoop of whey isolate after training or with breakfast, and a daily serving of creatine taken at any time of day. Everything else is optional and should earn its place based on a specific goal.
Pricing, shipping and the guarantee

How it compares
Against mainstream brands such as Optimum Nutrition or Cellucor, Transparent Labs usually costs more per serving but wins on label disclosure and ingredient choices. Compared with other premium, certified brands such as Momentous or Legion, it is broadly similar in price and philosophy, with a wider flavor range and a heavier focus on bodybuilding staples. True Nutrition can be cheaper for bulk protein, especially if you want a custom blend, but with a different testing and branding approach.
Who it suits
Transparent Labs is ideal for experienced lifters, athletes in tested sports, and anyone who wants to know exactly what they are taking. Beginners also benefit, since the clear labels make it easier to learn what effective doses look like.
It suits budget shoppers less well, and people who strongly dislike the taste of stevia may prefer other sweetener systems. If you are new to the brand, a single tub is a low-risk way to test flavors before committing to bundles. Stimulant pre-workouts are not suitable for everyone; see the health note.

Transparent Labs is one of the most trustworthy sports nutrition brands we reviewed, thanks to full dose disclosure, sensible formulations and third-party certification. Start with the whey isolate or Creatine HMB, take advantage of free shipping over $99, and use the 30-day guarantee if a flavor does not work for you.
