WHEY BLEND BREAKDOWN

25g Whey Protein. 6g Hydrolysate. 13g Isolate. 6g Concentrate.

WHEY ISOLATE

Great for low-carb diets, low in fat, and easily digested.*

WHEY CONCENTRATE

Concentrate has a more balanced amount of proteins, carbs, and fats to fuel your workouts.*

WHEY HYDROLYSATE

This whey protein has been hydrolyzed, or broken down into strings of amino acids called peptides, for even faster absorption than standard whey!*

DIGESTIVE ENZYMES

These enzymes help with the digestion of your protein.* In fact, they are clinically studied and shown to increase the uptake of amino acids into the blood by 20% compared to whey protein given alone.*

Bodybuilding.com Athlete

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, Bodybuilding.com was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our Signature line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.

TOTAL TRANSPARENCY

Signature products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.

EFFECTIVE DOSES

An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. Signature supplements always include enough to get the job done.

RESEARCH-BACKED INGREDIENTS

Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in Signature products because that’s what works.

I like the product but chose the wrong flavor. It your not big on vanilla you probably wont like Birthday Cake taste. It taste like vanilla with little cake topping sprinkles in it. I should have stayed with my fav Mocha Cappchino.

My go-to whey protein is ON's Gold Standard, but I gave this a try because it was on sale and bodybuilding.com\s brands that I've tried have been good. I got chocolate and it tasted good. It was easily digested. It was "foamier?" and slightly thicker than other proteins I have tried when fully shaken up. Only complaint is that it did not mix easily. I have to leave a good amount of "headspace" at the top of my mixing bottle, and shake the heck out of it for 1-2 minutes to get all the powder chunks broken up. Other than that solid protein powder that tastes great, goes down easy, and gives the muscles what they need after a workout.

All of the flavors I have tried of the Signature 100% Whey Protein are delicious and mix easily! Some flavors are more deep/intense than others. I would say Mocha Cappuccino is my favorite!

The sample of Vanilla is what got me hooked! I had ordered a different brand of protein & no longer wanted it after trying this brand lol. Vanilla mixes very smooth and tastes creamy/savory, I was loyal to that flavor until craving new ones. Birthday cake is perfect for when I am craving sweets without messing up my nutrition. I cannot wait to try Oatmeal Cookie next, this is my favorite protein I have tried!! I have lost 30lbs and finally have a 6pack without feeling hungry/starved thanks to this protein + the delicious flavors. A lot of helpful reviews on here, big thanks to everyone's honesty so that I can know which flavors to try in the future

Received vanilla sample and tasted good so ordered 5lb strawberry and 5lb mocha cappuccino, im a skeptic person cause i have been using optimum 100% whey for years and years with never a stomach issue or anything but their flavors are not all that but i like the quality but when i took 2 scoops first in only water of this in strawberry it tastes soooo satisfying and creamy delicious, i loved it, optimum never tasted like this or any other protein powder i have ever tried in the past, next day i tried the mocha in water and it was also just delicious and satisfying and i can imagine in milk they must taste way better but i was testing them out, dying to try the oatmeal after reading reviews but i will not waste money on 2lb jars so if they ever carry it in 5lb i will order. Only thing is also i do get way more servings out of the optimum for the same pounds but im sold on these flavors, birthday cake and oatmeal need to be in 5lb jars

I received the vanilla as a sample in my last order and was blown away by the taste. Delicious! You made a customer out of me for this product. Will try the oatmeal cookie too.

Doesn’t break down very well (plenty of chunks leftover) which makes it’s pretty watery to drink. Nothing inherently wrong with that, but compared to a product like Jym or even just Whey, I was expecting more. Also a little too sweet, but that's personal preference.

They sent me a sample of this with my order I received this morning. I can honestly say it's the best tasting vanilla powder I've ever had. Very smooth and easy mixing as well. Will definitely consider purchasing this next time I need whey.

I received my Bodybuilding.com Signature Whey Protein a few days ago. I usually take 1 scoop evenings with milk the nights before I workout in the mornings and 1 scoop after my workouts. This protein is very tasty and not too sweet. I like that it does not bloat me like some others. I like the price, too. I trust BB.com ingredients and have been a buyer of their products since 2004.

Didn't know what to expect when ordering this, but was happily surprised with the taste. Makes everything taste like a cake in a good "whey." Very versatile and mixes well with most everything!
