Clean ingredients & taste

A clean formula, easy to drink in minutes. I have another type of protein drinks that I take my sweet time to finish it due to its powdery texture. Now that I have this one, I drink it on workout days and have the other one on rest days.

Best Tasting Protein Powder, and Doesn't Mess With My Gut!

Probably the best-tasting protein powder I have ever used. Also, with other brands, my stomach would sometimes hurt after drinking a shake and I would be bloated for several hours, but I have not experienced that one time with this powder. The clean ingredients definitely make a difference.

Smooth mixing, great tasting

Never had a protein shake that mixes so smoothly. I just use a regular cup and spoon. The oatmeal chocolate chip taste great with a normal, not fake aftertaste, which I’m usually picky about. We’re definitely buying again.

Extremely happy with this product

I was so happy with my purchase the peanut butter protein powder is my new favorite. I also bought the oatmeal chocolate chip cookie - which is also delicious. I have a sensitive stomach - and this protein powder was great and no stomach issues. I love getting 30 grams of protein per serving.

Alison F.

Love the flavor and blending

This is the best-tasting protein I have ever tried. It dissolves quickly and the chocolate flavor is far superior to other chocolate flavors I've tasted.

Best Protein I've ever used

Best I have ever used. Very clean.


Able to reach my 200g daily protien goals with zero discomfort.

The protein powder I've been searching for!

It's amazing how tough it is to find a quality protein powder without a bunch of extra ingredients but thankfully, this is it! Simply high-quality whey protein isolate, thanks TL!

Wesley C.

Perfect Protein

This is legitimately the best isolate protein I've ever had. Its formula, the texture and taste, it all is high-quality, and the word 'clean' just comes to mind whenever I set my workout shakes up.

The Real Scoop

Transparent Labs Protein vs. The Others

Comparison of two protein supplements: one highlights protein content and natural ingredients, while the other indicates artificial sweeteners.

Paul Sklar - Transparent Labs Athlete

“This is the key to building muscle after 40.”

I’m 52 years old, a father of 5, a former professional athlete, and personal trainer for 25 years - and the one thing that I’ve found to be most important when training at this age is maintaining a high protein intake.


I care a lot about everything that goes into my body, and Transparent Labs is by far the cleanest protein out there.


I usually take 3 scoops a day - one and a half scoops in my breakfast shake, and another one and a half scoops in my post-workout shake.

What’s in your “Natural Flavors”?

The natural flavors used in our products are derived from natural sources such as plants, fruits, or spices. For example, the organic compound isobutyl acetate is found in raspberries, pears, and pineapples and is used to impart natural fruity flavors.

Food labeling practices require the term "natural flavor" to be used instead of the specific constituents that comprise the flavoring. We prioritize using natural flavors to provide a clean and enjoyable taste experience for our customers.

If you're looking for a whey protein isolate with no natural flavors, try our Unflavored option!
