Vanilla Milkshake tempts your tase buds with a creamy, smooth texture, with balanced notes of natural vanilla and a smooth sweetness.

What are LactoSpore® and BioCore® Optum Complete in the PERSIST™ WHEY ISOLATE?

LactoSpore® is a commercial probiotic preparation containing L(+) lactic acid producing microbial preparation from Bacillus coagulans, MTCC 5856 (earlier known to be Lactobacillus sporogenes). Probiotics are well known to improve gut health and digestion of macronutrients such as whey protein.

The human digestive tract contains about 400 different bacterial species that reduce the growth of harmful bacteria and promote a healthy digestive system. And lactic acid producing bacteria are the largest inhabitant group amongst all. LactoSpore® produces L(+) lactic acid, grows in the temperature range of 35 °C to 50 °C and the optimum pH range is 5.5–6.5.

BioCore® Optimum Complete combines the full spectrum digestive enzyme support of BioCore Optimum with alpha-galactosidase and lactase to help support individuals with specific digestive issues, such as proteins, fats and starch. This product is a lactase that supports a more complete digestion of dairy foods and is active throughout the pH range of the entire digestive system. It is an alpha-galactosidase that helps prevent intestinal discomfort and flatulence.

Some of the best protein powder I have purchased. I generally use the pack from Costco, but the Undefined Nutrition Vanilla Milkshake is SUPERIOR in both taste and mixability. It is especially good as a vanilla ice-cream in the Creami. Thanks, Shaw Family!

This protein is the most delicious and highest quality protein I have ever tried. It mixes perfectly leaving no chunks for me to have to drink. It tastes incredible, just like I'm drinking a milkshake. I look forward to it every day as someone who really tries to limit their sweets in their diet. I have been working out for 16 years and this is the first protein I have ever purchased after having tried many other samples of proteins I have gotten in the past. Knowing it's developed by a family and team that cares about quality and the athletes that make up their customer base is awesome as well as it being made in America. I will only ever buy this protein. 10/10. 100% satisfied.

Customer photo review of PERSIST | WHEY PROTEIN ISOLATE

Of all the different brands of protein powder I’ve tried at GNC, NOTHING comes close to the Persist ISO. The most delicious & flavorful protein I’ve ever tasted! It actually tastes like a chocolate milkshake. I was even bummed because the chocolate pb was sold out but I’m glad it was, I don’t even want to try another flavor. Shipping was instant, placed my order on a Friday afternoon and it was already being shipped that same night. Got it first thing Monday for my workout and I’ll definitely be subscribing to keep my shelf stocked! Also the family owned business vibe is awesome, the postcard with Brian on it and I’m not sure who but someone (I hope it was Keri lol) signed my invoice, little things like that letting us know we matter to you guys is why I’ve been following the journey since I started working out in high school!

Already out need more. It was great. I hope you buy some too because it was worth every penny.

PERSIST | WHEY PROTEIN ISOLATE

The entire Persist line is great. High quality, dissolves easily, no chalky residue and tastes great. I'm having a hard time deciding if Coffee Ice Cream or Peanut Butter is my favorite flavor. The Chocolate fudge brownie mixed with warm milk is an excellent high protein alternative to hot chocolate.

PERSIST | WHEY PROTEIN ISOLATE

PERSIST | WHEY PROTEIN ISOLATE

Love this flavor. I feel so many powders out there are way too sweet. Undefined products are great the ice cream coffee flavor is my favorite. I use it in my coffee in the am to give me a quick on the go breakfast. It fluffs up with my frother (some milk and creatine too) beautifully! Protien cappucino anyone!!!

PERSIST | WHEY PROTEIN ISOLATE

Works well. Taste great. Wish it came in bigger bags or tubs. Repeat customer

PERSIST | WHEY PROTEIN ISOLATE

This definitely helps with my lifelong GI issues, which have improved by a good 25% since I started using it. Other powder's I've used don't help, some make things worse. Taste is very good and mixes very easily in water and/or milk. I have the shaker bottle as well, which mixes everything up quite nicely and quickly. One minor issue is the bag doesn't seal up very well. I just stick it in a larger ziplock bag, problem solved. Recommend 10/10!!

PERSIST | WHEY PROTEIN ISOLATE

My first time trying the protein powder from Undefined Nutrition. The flavor is absolutely amazing. It also dissolves in the water/milk perfectly. I will absolutely buy more.

PERSIST | WHEY PROTEIN ISOLATE

So long time fan of Brian Shaw long fan of strongman, i ordered this protein with the mindset of “if i wanna be the best i gotta train like the best”. I read the reviews and everything says the same thing, “i love it, best protein ever, taste amazing!” So here’s my 100% honest review while keeping it respectful. Packaging- saw the box and was super excited because this was my first item ever purchased from here, and to see the Shaw logo was cool and gave me a sense of pride. Once i opened the box i saw a bag. Was a little confused/ disappointed but i said ya know what it’s what’s in the bag that matters. Then i opened it and had to fish through the bag to find the scoop (honestly thought it didn’t have one at first) Taste/mix- i got the chocolate peanut butter flavor because it’s a safe first choice. I did one scoop in my 20oz of whole milk and shook it for while. I was so excited for my first sip of the 4x SBD WSM protein shake, and when the drink finally hit my lips i thought “really? This is the best protein powder ever?” The taste was mild and i still had clumps of powder throughout the shake. So i was kinda let down for the price of the protein for the return i got. Maybe i hyped myself up and expected more? But all in all if i gave this a 1-10 rating…. I’d have to say 7.3 out of 10. Hope i said this as respectful as possible while keeping it honest. I’d love to hear back from the team and hope yall are doing well. Stay blessed and enjoy your day.

PERSIST | WHEY PROTEIN ISOLATE

This is the best protein powder I have ever had. It tastes like chocolate milk when I have it. You can’t even tell it’s protein powder when you’re drinking it. I will definitely buy again.

PERSIST | WHEY PROTEIN ISOLATE

We love this flavor! My son loves his chocolate protein. Easy way for a parent to make sure their child is getting top quality protein for their diet when on the go.

PERSIST | WHEY PROTEIN ISOLATE

I bought the whey isolate protein mix. I had to try the coffee ice-cream flavor since that's my favorite ice-cream. It's a strong coffee flavor. I only tried it with water so far. I feel bigger and stronger all ready. The purchase and shipping was easy and came on time.
