650 CALORIE EXTREME MASS GAINER PROTEIN

There are mass gainers, and then there’s NutraBio Extreme Mass. What sets this mass gainer apart from the competition is its clean formula that provides you with everything you need and nothing that you don’t — helping you add the quality size you want during your bulk without the additional body fat.

NutraBio Extreme Mass gainer uses two premium protein sources to help you reach your daily intake — whey protein concentrate (WPC80) and micellar casein. This one-two protein punch provides you with an immediate source of amino acids while also providing a sustained release for upwards of seven hours. Not only will Extreme Mass help you add lean muscle mass and improve recovery, but it can also aid in muscle preservation and prevent the breakdown of your hard-earned muscle.

WHY CHOOSE EXTREME MASS?

HIGH CALORIES & LOW SUGAR

It’s quite easy to consume everything in sight to put yourself in a caloric surplus. Unfortunately, the foods you choose could cause you to add more body fat than lean muscle. NutraBio Extreme Mass solves this issue by providing you with an ultra-clean mass gainer loaded with 53g of premium protein and 100g of quality carbs. Best of all, Extreme Mass is low in sugar, setting the industry standard for what a mass gainer should look like.

PREMIUM PROTEIN SOURCES

Extreme Mass combines fast-absorbing whey protein concentrate (WPC80) with slow-absorbing micellar casein in a 70:30 ratio. On the one hand, you have whey protein concentrate that leads to a rapid spike in amino acid levels to kickstart the recovery process and spark new muscle growth. Then, on the other hand, you have micellar casein, which tends to have a more anti-catabolic effect and a much longer and steady release of amino acids for upwards of seven hours.

CLEAN CARB TECHNOLOGY

An area that truly sets NutraBio Extreme Mass apart from the typical mass gainer is its Clean Carb Technology. Our maltodextrin isn’t what you expect to find in a standard mass gainer. Rather than using cheap maltodextrin, we used patented Fibersol-2®, which is a digestive-resistant maltodextrin that won’t cause a massive spike in blood sugar. The use of Fibersol-2® not only helps prevents the conversion to fat but also enhances glycogen replenishment and slowly breaks down glucose over a two-hour period to supply the body with a controlled, time-released, and continuous source of energy.

MUSCLE GROWTH & RECOVERY

The combination of whey protein concentrate (WPC80) and micellar casein, together, can lead to greater increases in lean muscle mass and shorter recovery times compared to when ingested separately. Even more impressive is that recent scientific evidence suggests that the proteins used in our mass gainer may boost IGF-1 (insulin-like Growth Factor), which helps the body burn fat and build muscle. If muscle growth is what you’re after, NutraBio Extreme Mass can help you pack on the added size you’re looking for.

INGREDIENTS

Whey Protein Concentrate: This high-quality WPC80 is CFM cross-flow micro- and ultra-filtered to provide a clean and instantized whey protein concentrate that is easily digested and helps provide the muscles with the amino acids needed to support lean muscle growth and recovery.

Micellar Casein: This is another form of protein that is derived from milk. Only this specific source is known as a slow-digesting protein, meaning that it releases amino acids into the bloodstream at a much slower rate than other types of protein. Due to its slow release, micellar casein is a popular choice for use before bed, as it can provide a sustained release of amino acids to support muscle recovery and growth during sleep when normally you would be in a fasted state, and catabolism may set in. Micellar casein is also commonly used in protein blends to help individuals stay full longer and extend the release of amino acids to support muscle recovery and growth.

Maltodextrin: Made from vegetable starch, this ingredient is commonly used as a low-calorie sweetener.

MCT Coconut Powder: This medium-chain triglyceride is more easily digested when compared to other fat sources. This healthy fat is known for its ability to support a healthy weight, energy production, lactate reduction, and blood sugar management.

Digestive-Resistant Maltodextrin (Fibersol2®): A patented prebiotic fiber that can help improve satiety, increase soluble fiber intake, and better manage blood sugar levels.

These really are durable and tough!
OMG! I have 2 large dogs. A 90 lb.golden retriever and a 75 lb. black lab mix. They LOVE to chew and every squeaky toy I have bought for them is demolished in less than 2-3 days! Even the KONG brand. I have spend hundreds of dollars on various dog toys, chews, squeaky toys, etc.None of them stood a chance! LOL So, I saw these "stuffingless durable tough" snakes and decided to give it a try! Why not? My husband even told me NOT to buy them as they would just be torn apart in days. The snakes came and each dog got one. I ordered 2 of the same color in red. At first, they weren't quite sure what to do with them as they are pretty long. Approximately 2 feet. They slowly began to trust that this was indeed a "toy" and began chewing on them and our golden retriever was tossing the snake up in the air and biting down on it as it fell to the ground. I also like the fact that the squeakers are a low volume and not so high pitched squeak! Well, long story short, they have now had the snakes for 6 days and they are still intact and the dogs absolutely love them!!!! I am so happy I finally found a dog toy that my dogs don't destroy!!! I will definitely be buying more!! Lainie Sammamish, Washington

A winning toy!
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
This is the best dog toy ever! I have a Cockapoo that is 8 years old but thinks she is 2. She chews up everything so I've gone thru a lot of dog toys. This toy has lasted 6 months - truly record breaking for her. It's become all raggy so time to get a new one. Thank you Nocciola for inventing a quality fun toy that lasts. Photo shows toy after 6 mo. of playing tug of war!

Winner of the aggressive chew competition
Color: No Stuffing Blue Eel
I bought several toys for an insane Jack Russell and this is the unlikely winner. It is a softer toy, but it is stitched together nicely and there are various components that distract the dog and keep him busy. First, it can be rolled up and stuck with small but strong Velcro patches, so it’s not just a sitting duck, the dog has to figure out how to unroll it which is fun. Next there are five little pockets on one side that you can put treats inside, which draw attention to the toy and give him another task. He did partially rip some of the flaps on the pockets in his zeal to get the treats. Then there is the squeaker, which he dispatched of in like 4 seconds (somehow without ripping the fabric(?)), then there are all sorts of crinkles and textures on both sides. All of this and the good stitching make it a toy he wants to play with but that he doesn’t annihilate in one day. The hard plastic toys are also good but I feel like I need to watch him carefully for fear that a sharp chunk will come off. The medium chew toys are cool but he’s just not into them. So this wins!

My dogs favorite toy!
Color: Blue & Yellow Eel Bundle
This is my Jack Chi and Yorkies favorite toys (it helps when they get 5 mini milk bones). It is a tough toy, but not impervious to a Jack Chi determination to remove all squeekiees! Squeekie or not, it's still their favorite toy for tug-a-war.

Fun Toy
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
My dog loves this toy. It has 2 squeaky & also has crinkly sound along with the slots for treats. However it is not very durable. The treat slots were pretty much destroyed with the first use. I'm still giving it a 4 star because it is so fun & entertaining for my GSD.
