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.

All the flavors are good, except Mocha Cappuccino. although ultimately it’s up to personal preference. I tried really hard to like it, but I couldn’t. It smells terrible, somewhat like dog food, and the taste is identical, dog food. The best flavor by far is the Oatmeal Cookie that they appeared to have gotten rid of unfortunately. Vanilla is always a safe bet.

Mix with a little bit of cold water or milk then add to coffee! Boom! pro tip: make sure to mix into cold liquid first! Don't mix directly into coffee or you'll have a bad time, it won't mix well

Overall, it's protein, doesn't need much of an introduction. But the vanilla taste is just awful. I'm really not a picky eater but the very first portion of the vanilla I just had almost made me gag. Maybe I'll get used to it, but I'm not looking forward to this 5lb tub.

I was actually REALLY surprised. I got chocolate for my protein pancakes and mocha cappuccino for my coffee, I wasnt sure what to expect taste wise, the chocolate cooks exceptionally well when added to my pancakes, for me, the taste is subtle, which is fine for me, it does taste very delicious, the mocha cappuccino took some trial and error for me, but once I found out how I liked it, it was absolutely delicious.(tip: if mixing with coffee, the colder it is, the better it tastes IMO), I am throughly impressed with these protein powders and will be ordering this from now on!!

Not a bad strawberry flavor at all. My only complaint is it would sometimes clump up while mixing, resulting in those dreaded chalk protein clumps. But besides that it has a great profile and tastes great. Usually strawberry is hard to flavor, but does a fantastic job

Why does it say discontinued when I try to reorder the Oatmeal Cookie Flavor. IT was easily the best flavor has and I switched to that brand because of it? Could someone from please respond? I have tried to get a customer service agent on live chat but they are never available? What's going on gang?

I've only used strawberry but it's one of the few great tasting strawberry proteins out there. My main issue with this product is the scoop. Can you guys at come into the 21st century with the rest of us? I get this deep 5lb container and a scoop with a little snub nose handle, not even a normal size handle, it's smaller than that. It would be great if would follow other companies and give us a scoop with a longer than average handle so I'm not dragging my knuckles across the bottom of the plastic. I'm sure we'd all gladly pay the extra $.40 per container for that luxury.

The best tasting and quality protein for the best price I have gotten! I am a huge chocolate/ coffee addict and started with the chocolate protein. Mix it in with some almond milk and ice and it turns into my guilty pleasure of a chocolate milkshake. When they mocha cappucino came out, I questioned it because most coffee flavored protein I have had tasted like crap.. But I'm so proud to say that they nailed this flavor! Who needs a mocha frap fro starbucks when I have this now!

Tastes like the end of an Irish Carbomb. I'm a pretty regular buyer off BB and pride myself on not being very picky but it's going to be tough getting through this 5lber.
