Product Overview

Proudly supports first responders & nurses with and Verify Here 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.

Maple glazed donut discontinued? What is wrong with companies killing off good flavors. This was a great breakfast shake.

I have to piggy back off of the review I just wrote as I left something worth noting out. A mistake with shipping cost was made when I ordered yesterday. I emailed support and Kardio Kelly was more than happy to make this right for me and in the way that I requested. They responded very quickly to my email and they way this situation was handled has pretty well sealed the deal on me being a long time customer. Great company with great products!

I loved the price and how the protein tasted. I thought that the macros can compare to most big brands and for the price it is unbeatable. I have bought numerous flavors of this protein and will say that I have loved all of them. From chocolate peanut butter to birthday cake everything is amazing. Highly recommend!

Been using this protein for about 6-8 months now. Great taste and mixes really well/easy. By far my favorite current protein on the market. The flavors are true to taste. No chalkiness, no clumping.

I have "protmeal" (oatmeal mixed with whey protein powder) 5-6 times per week. It's one of my go-to meals. I've typically used vanilla flavored whey but now use the Oatmeal Cookie flavor almost exclusively because it is so good. When my wife smelled the aroma of the Oatmeal Cookie "protmeal", she tried it and now she has it for breakfast nearly every day.

Love the protein, but why all of a sudden is it never on sale? The whole reason I started using this protein was price. I feel like for this price I would rather spend a little more and go with gold standard.

Better than the Oatmeal Cookie and the Chocolate Peanut Butter. If you have a sweet tooth and like blueberry cobbler, you will LOVE this protein. So happy they released this right before cutting season because it is lower in calories and tastes soooooo good (even in plain water). The only downside is the mixability; then again, I only used 10 oz water for 2 scoops (but usually oatmeal cookie would still mix). Have been lifting for almost a decade and this is the best I have ever tired
