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.

Holy Grail Moisturizer for Rosacea
Style: Restorative Protective Cream-3.3 Fl Oz
In seeing so many negative reviews I felt compelled to weigh in as this is my favorite moisturizer. I have very dry, menopausal skin. Additionally, I have rosacea which seems to have been a nice gift from said menopause (you can only laugh, right?). It's very common for those of us in our 50's to have a compromised skin barrier and when an issue like rosacea is present, even more so. Because of all this my skin is very intolerant to most moisturizers and nearly all actives (over the last few years I've had to discontinue my retinols and chemical exfoliators). While ingredients like ALA's, petrolatum, mineral oil, parafin/bees wax, and lanolin are well tolerated and known to be quite soothing, they don't hydrate very well as they are more occlusive than moisturizing. Enter this product. Magically, it does both! It's marketed as a protective cream, which again implies occlusive, but it penetrates like no other. Gone is the tight, dry feeling that persisted even when I had a heavy layer of product on my skin (my previous moisturizer was Eucerin Original Healing Cream -- which still has its uses -- because it was the only thing I could put on my skin outside of squalane oil during a flare). Now, no topical can cure rosacea. However, the right product can calm the skin, repair the damaged lipid barrier, and improve its appearance. This moisturizer does just that and it's become my holy grail. Since starting this I've also added in the Cicalfate Serum which has only aided in repairing my skin. Another Avene product that works great for me is the XeraCalm Balm which helps with itching. I use all three of these daily and they've really helped fix the secondary issues that come with rosacea. As for the complaints about it being greasy or too heavy. I can see this not working for people with normal or oily skin (or perhaps only in moderation). But my skin loves the heavier weight and because one of the ways I soothe a flare is to keep a tiny mister bottle on hand and repeatedly spray my face so I have to guard against the drying effects of evaporation. These products are so lipid heavy that I can wet my face all day long without worrying about that, though I do reapply throughout the day. As for the watery consistency issue, I haven't had that problem but it does caution on the packaging not to expose the product to temperatures below 41 degrees F (5 C). I suspect that if it gets too cold either because of the weather or because of whatever warehouse it sat in during transit it will separate. Maybe open the package and before squeezing some out look to see if it has split and then shake it up/message the tube. So, if you have skin like mine don't hesitate to try this product. I'm leaving this absurdly long review for my struggling brothers and sisters out there with rosacea in hopes that it provides some relief! Happy moisturizing, internet strangers. ;)

Possible solution to seperation
Style: Restorative Protective Cream-1.3 Fl Oz
I love this product so much, but, like everyone else the water HEAVILY separated. A lot of water just shot out immediately and as i've used the cream it has felt more and more thick bc of that, shaking the tube or not. POSSIBLE SOLUTION: I actually think the company could salvage this problem by upgrading packaging to a Cosmetic JAR and then customers could take a toothpick and stir if separation has occurred by the time of purchase. I hope to try this with my next tube, just toothpaste squeezed everything out into a nice cosmetic jar and stir the water back into the product. This is such a simple solution that could really solve the product waste. This refreshes my skin, doesn't break me out, and is lovely. I break out so easily, and being middle aged my skin really requires a dense help with moisture. <3

Ordered in spring/summer and it arrived separated too BUT...
Style: Restorative Protective Cream-1.3 Fl Oz
Ok, So I heard great things about this cream and decided to order. I ordered on May 28th and I live on the Gulf Coast of Texas and it is in the low 90s right now. I was worried mine would arrived separated like many others claimed to have gotten theirs, and sadly it did. Warm weather or not, blue water shot out of the tube the minute I squeezed it. Luckily, I read Mia P's review and submerged my tube in warm water (hot water actually straight out of my instant hot water faucet). I left it for about 5 minutes then shook it vigoroously. It seemed to help but was still a bit wonky so I repeated the process again and success! My tube is totally fine now and comes out in a thick, rich, emollient cream as it is supposed to. I will update my review after I use it more but so far I love the way it feels on the skin. It is very thick but spreads nicely and completely absorbs into the skin and leaves no greasy residue which is a big deal because I have oily skin. I purchased this to help with my Retin A uglies (I actually am using Musely with .05% tretinoin) and am hoping it helps with the redness and peeling I am having. I will update my review once I've used it for a while but wanted to post this review as I saw so many people complaining about the separating and just thought I'd mention that you can fix this issue if you have it (and there is a good likely hood that you will). Update: I've been using this for a week now and I am absolutely in love with this cream! It is the most hydrating and healing cream I've ever used. Usually, thicker face creams like this would cause issues for me with acne or clogged pores as I do have oily skin that can break out if I use products with occlusive ingredients, but this one does not. In fact, my skin has never looked better! This is a must-have if you are using Retin-A/Tretinoin and going through the red/peely phase with your skin. The separation that occurred when I first received it has not been a problem and the cream is staying thick and free from any strange liquidy issues after I put it in hot water as mentioned in the first part of my review.

Saved My Skin and Healed My Eczema
Style: Restorative Protective Cream-1.3 Fl Oz, Style: Restorative Protective Cream-1.3 Fl Oz
I was having the worst skin winter of my life. I am hypersensitive and my skin started rejecting an expensive line I had used for many years (EL). My skin wasn’t healing even just using AQ balm on it and occasionally steroids when it was extra bad, and the pronounced eczema on my eyelids and neck for months was making me miserable and gross looking. I started researching brands I hadn’t tried for super sensitive skin and saw recommendations for Avene. We were leaving on a vacation and I was desperate to feel better so I ordered this and the matching serum. I started with only this cream and overnight I saw my skin start to heal. Within a few days it was like the last few months never happened. I carefully added the serum and had no issues. I used only these two products for the month I was gone and had glowing skin the whole time. This is thicker than a normal lotion since it is made to protect your skin but if you let it warm up a few seconds it smoothes easily. This will definitely remain a staple in my skin arsenal and I can’t thank you enough for making an actually gentle but effective product! This picture is two weeks after starting the product, smooth skin and confident to take selfies!
