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 got the chocolate and it was too sweet for my liking. It does have a nice consistency if you like thicker shakes. For the price, it was good, but not great.

Very happy with this product!! I've been looking to replace ON Whey Protein because I've been using it since day 1 plus the value from Costco. I'm happy to say that I will be converting to BB Whey Protein now on. Oatmeal cookie is my favorite cookie type and I'm so glad that they made it as a protein flavor!! Taste is spot on and mixes easily with water. I do have to say it might be a little sweet for some people, butit's no where near as sweet as MP Cookies and Cream

Uhm.. I'm not sure if I've lost it or did the product's contents suddenly change on me? I could've sworn this had at least like 65 G of Protein with 700 + Calories.

Protein was ****. Flavor was ****. Gave to a friend and wasted my money. Ingredients were also ****. Thought it was suppose to be comparable to gold standard. Also they are putting carrageenan in their protein.

This is a nice protein powder for a cheap price. The oatmeal cookie flavour is really nice in my opinion, tastes like cookies with cinnamon. The chocolate however is not that great but just ok, the dymatize flavour i tried was much better. Honestly if you are looking for the greatest tasting protein this is not for you.

Honestly I couldnt stand the oatmeal cookie flavor. First couple times it tasted ok but every other time I've used it I gag a bit not going to lie. The product itself is great. Oatmeal cookie flavor itself is just not good. I've tried with milk, and with water. Different liquid to powder mixture. I usually use the least amount of liquid that's recommended just so I can drink it down real fast. Idk how to even describe it but it's just not good in my opinion.

The oatmeal cookie flavor is amazing. It's actually crazy how accurate the flavor is. It's truly the best flavor offered by bodybuilding.com and maybe even the best flavor on the market. Mocha is okay. It's good but nothing special. Birthday cake is really good too but tastes very similar to Vanilla. It's not that strong of a flavor when compared to oatmeal cookie. Oatmeal Cookie is just in another league of it's own.
