Product Overview Signature 100% Whey Protein

Whey protein is the most important weapon in your muscle-building arsenal. It promotes muscle growth, counteracts muscle breakdown, and supports your workout recovery.*

Bonus: It’s also easy to digest and a source of powerful BCAAs.* Our Signature 100% Whey Protein combines three hard-hitting types of protein in one powerful blend. It’s perfect first thing in the morning, between meals, and especially after your workout. It’s so delicious, it’ll also slay that sweet tooth! Signature 100% Whey Protein tub


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


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


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


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


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.* Athlete

A signature is a promise. A symbol of your identity. Your mark on the world. In 1999, 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.


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.


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.


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.

OATMEAL COOKIE. It tastes like Christmas. I sprinkle some cinnamon powder in with the shake and it tastes amazing. Mix it with plain greek yogurt and it's amazing! This flavor should be year round.

OATMEAL COOKIE, I can not express the joy that this flavor has given me!! I thought BPI had mastered the Whey Protein market with amazing taste but after drinking Bodybuilding's Signature with the Oatmeal Cookie flavor, I have found Protein Nirvana. I can finally stick to my shake habit and satisfy my inner fat kid all at the same time! Guilt Free!

I am VERY disappointed in this product. I used two scoops with water in a 24-ounce shaker and the sweetness was unbearable. I was forced to drink several ounces fill up with more water and it was STILL super sweet. What kind of synthetic sweetener does this product have with only 4-grams of carbs and a sweetness that's unbearable!? I know that we have different thresholds for sweetness but I don't think anyone can argue that this product is absolutely too sweet, to the point of unacceptable. I won't be buying this product again and I'm very disappointed about this, especially since I bought 10-pounds of this protein (strawberry and vanilla that I haven't opened yet).

We love this protein and the great taste that comes with it! It's hard to find a protein that actually tastes good and you can get a decent amount of protein with it and this is perfect! We use the vanilla in a lot of our baking and it works perfectly!

I bought this protein because I’ve been wanting to try something new and the reviews seemed great. Well... I was very mistaken when I tried it. The first time I thought,”well maybe I didn’t mix it well enough”. Because it didn’t mix well at all, unless you enjoy having to chew your protein drink. Then same thing the second time. And the flavor just tastes cheap, it’s a very “protein-y” taste, which some people may like. I prefer my protein to have a flavor that makes me want to drink it, it keeps me from going and getting sweets. I will not be buying again, I’ll be sticking to what I know from now on.

Not the best tasting protein and it doesn’t mix that great. I compare it to Gold Standard and I would rate Gold Standard a 9/10.

Mocha Cappuccino is my fav! All of them mix very well, both with water and milk. Oatmeal Cookie and Strawberry are tasty but a bit on the sweet side. Strawberry is a little like confetti birthday cake flavor. Vanilla is creamy, more of the neutral one that you can mix with anything and will taste great! I am on my 5th shipment of the 5lb tubes. Bodybuildings protein powders are really good and a great value.

First time buying this store's own brand of whey and I am impressed by the oatmeal cookie flavor. It is kind of like BSN Syntha 6 cinnamon bun but minus ton of carbs like dextrose which BSN uses. The flavor is strong even though I used 1.5 servings in about 500ml of cold water. Maybe the sucralose dose is very high or the sucralose in the container did not get mixed evenly and most of it ended up at the top. They should make this oatmeal cookie flavor for their casein product, or release a pure egg protein powder with this flavor. Great work.

I'll just paste what I posted on the community site.... Thats how much I am in love with this Oatmeal cookie flavor!! Ok guys, I do not work for but man I cant help but mention how awesome their Oatmeal cookie flavored protein mix is......... So good that I've already been using it in my pancake mix and so good I had to use it to duplicate my late Granny's "Christmas Cookies" (basically an oatmeal cookie with PB, coconut, and chocolate chips) I literally just drank Christmas cookies. Ive had a lot of different proteins and this one for me is the best Ive had, the flavor is pretty freaking amazing and the only thing that sucks about it is that it's only available for a limited time :( As for additional items, the Macros are on point for my use and it mixes really well!! I need to order more before they stop making them :(
