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.

It’s ok
Size: X-Large, Color: Gray
This jacket is OK. I bought it for my boyfriend because I really like the coat collar but once it got here. The front fits well but I think the back needs a little more tailoring because it kind of sticks out but he really liked it. He said he could put a heavy sweater up under it. That way he can get more ware out of it. It’s OK.

NICE AND STRETCHY
Color: Navy Blue, Size: 42
These pants are made of a material that seems durable and is definitely comfortable, and they have a stretch band at the waist that can comfortably accommodate many different belly girths-- from slim to portly. The waist also has a drawstring. I'd call these light weight pants, as the material is thin. They aren't baggy at all and fit the natural contours of an average male physique. The pants have two fairly deep front pockets and one small rear pocket that can easily fit a regular-sized wallet. But, I would not recommend carrying a wallet in the rear pocket, as, due to the depth of the pocket being only as deep as the wallet is long, it might slip out as you move around, sitting and rising. If nature calls, and you need to pee, you will have to pull your pants down and excite anyone in the immediate vicinity, as there is no opening, either buttoned or zippered, in the front of the pants. So, in that respect they are kind of like sweatpants. I'd call these pants good for inside the house or wearing on the street. I like them despite the lack of a fly, so I give 5 stars. I see lots of Chinese, Korean, and Japanese guys around who like to wear this type of pant, but these fit nicely for generally larger and more robust Caucasians type physiques as well. You don't have to worry about a belt or a broken fly zipper with these. Of course they are made in China, but due to their vast experience selling clothing to Americans, the manufacturers are well acquainted with big masculine American bodies and their needs.
