Supplement Philosophy and Ingredient Sourcing

Transparent Labs doesn’t just talk clean—they build every product from the ground up with integrity. That starts with their approach to ingredient sourcing and testing.

Every product is made in the U.S. in NSF-certified, cGMP-compliant facilities. Ingredients are often sourced from reputable, natural suppliers, and each batch undergoes third-party testing for purity, heavy metals, and microbial safety.

This is a company that refuses to cut corners. There are no proprietary blends, no underdosed ingredients, and no artificial colors, flavors, or sweeteners like sucralose or aspartame.

Instead, they use naturally derived sweeteners like stevia, along with flavors that don’t taste like synthetic candy. Their labels even include full clinical dosages so you know exactly what you’re getting.

It’s a level of honesty that’s rare in the fitness world—and it’s winning fans fast.

Bestselling Products from Transparent Labs

Transparent Labs has more than a dozen popular supplements, but a few rise above the rest in terms of popularity, performance, and consistent customer reviews. Here’s a breakdown of top-sellers that users keep coming back for.

1. Grass-Fed Whey Protein Isolate

This protein powder is a flagship item. With 28g of protein per serving and only 1-2g of carbs and fat, it’s ideal for lean muscle building and recovery. It’s made from grass-fed American cows, cold-processed to retain nutrients, and completely free of artificial sweeteners.

Flavor-wise, it scores high. Chocolate and Vanilla are crowd favorites, but seasonal flavors like Cinnamon French Toast and Mocha also keep customers coming back. It mixes well, goes easy on the stomach, and doesn’t leave a chalky aftertaste—three major wins in the protein world.

2. PreSeries BULK Pre-Workout

This is Transparent Labs’ most well-known pre-workout. It’s designed for people who want energy and muscle pumps without the over-stimulated, jittery feeling. With 6,000mg of citrulline malate, 4,000mg of beta-alanine, and 180mg of caffeine, it hits hard in all the right ways.

What makes it shine is the clinical dosing. No underwhelming doses of key ingredients, and definitely no weird artificial flavors. Reviewers often mention it helps with focus, energy, and endurance—without any crash.

3. Creatine HMB

This unique creatine blend combines 5g of creatine monohydrate with 1.5g of HMB (Beta-Hydroxy Beta-Methylbutyrate). The combo is meant to amplify muscle strength while reducing muscle breakdown—a great option for lifters in a strength cycle or athletes in-season.

It’s unflavored, super mixable, and easy to stack with other products. Users report gains in strength, stamina, and recovery speed.

4. PreSeries LEAN Pre-Workout

Targeted for fat loss, this version of their pre-workout skips heavy carbs and sugar, instead including ingredients like acetyl-L-carnitine and theanine. It still offers energy and focus, but also supports thermogenesis and metabolism.

It’s ideal for morning workouts or anyone cutting weight but wanting to keep their performance high.

5. Intra Workout EAA

This intra-workout supplement combines essential amino acids with a blend of coconut water powder and taurine for endurance and hydration. It’s clutch for long training sessions or hot environments, and helps minimize muscle breakdown mid-workout.

Additional Product Categories Worth Exploring

Besides their top-sellers, Transparent Labs has expanded into several new supplement categories:

Daily Essentials

Multivitamin – High-quality, bioavailable forms of key nutrients without fillers.

Vitamin D3 + K2 – A potent dose of two vitamins most people are deficient in.

Immune Support – A smart mix of elderberry, zinc, and other immunity staples.

Wellness and Longevity

Competitive Comparison: Transparent Labs vs. Others

When compared to brands like Optimum Nutrition, Cellucor, or even Legion Athletics, Transparent Labs holds its own—especially in quality.

Unlike Optimum Nutrition, Transparent Labs doesn’t use artificial sweeteners. Unlike Cellucor, there are no proprietary blends. And compared to most mass-market options, you’ll usually get a more effective dose of each ingredient for the price.

That said, if you’re shopping purely for price, you may find cheaper options. But when it comes to transparency and clean formulation, few brands stack up.

Who Should Use Transparent Labs?

Athletes – For clean, banned-substance-free products.

Lifters and bodybuilders – Looking for strength, endurance, or mass-building.

Busy professionals – Who need on-the-go wellness support like protein or greens.

Health-conscious users – Wanting no artificial additives or shady labeling.

Vegans or vegetarians – With options like plant protein and stimulant-free products.

Their formulas are also accessible to beginners—there’s no need to stack five different products to get results. One well-formulated product goes a long way.

Final Thoughts

Transparent Labs has built its brand around truth, quality, and scientific integrity. And it shows. From carefully sourced ingredients to products that do what they say, everything feels intentional and refined.

It’s not just another supplement company riding fitness trends. This is a brand built for real people who care about performance, wellness, and transparency.

Yes, it may cost a bit more—but in exchange, you get peace of mind. No junk. No surprises. Just pure results.
