⭐⭐⭐⭐⭐ Great product and excellent quality. I started using NAKED Mass consistently and gained 20 pounds in just 2 months. It mixes well, tastes natural, and kept me feeling fueled throughout the day. If you’re looking for a clean weight gainer that actually delivers results, I highly recommend it.

I rarely (if ever) post reviews on things, but I felt that this product was different. No, I am not getting paid or sponsored by anyone, let alone Naked. But this protein powder has honestly been a game changer for me. I was very underweight. I am 5'10" and when I started taking this I was 125 lbs. Of course, I started working out (weightlifting only, no cardio) at the same time that I started taking this. After 18 months of taking this, I am up 40 lbs. Of course I have been eating "healthier" since I started my working out journey. But still, I eat semi-normal from Monday to Friday and on the weekends I eat all kinds of junk. I take this powder (with whole milk) every day from Monday to Friday, which is the days that I work out. If you have an incredibly fast metabolism like me and have always struggled to gain weight, this shake is a must. It's clean, you don't feel bloated afterwards, and you don't get digestive issues since it doesn't have any artificial junk. On a side note, get the unflavored one. The flavored ones are incredibly high in sugar. The unflavored one only has 21 grams of sugar (which seems a lot, but it really isn't after burning it during a workout). Instead of taking all 24 oz of milk with 4 scoops, what I do is that I divide them. I take 12 oz of milk and add 2 scoops before working out and then take the rest after working out. This way it gives me an energy boost to endure my workout. Also, I don't do any extreme exercises. Just standard weightlifting at home. I have a bench press and 2 adjustable dumbbells (from Bowflex) and I do a full body workout throughout the week. One of the things I said to myself at the beginning was that I wasn't going to be a slave to be eating all day long to eat my necessary macros. Thanks to this powder, I only eat 3 times a day (breakfast, lunch, and dinner) and take the shake as a "snack" before and after working out. It's a huge help to fill in any nutritional gaps you don't get through food. I have seen some people in the reviews say that they are not noticing any difference after a week or two of using this product. Keep in mind bulking up takes more than that. It takes months. And so does this product (like any other protein powder). If you also want to take it to increase muscle mass, keep in mind taking this and not working out won't give you any results. You have to take this + work out. On the contrary, you can gain weight (from fat) and spike up your blood sugar (due to its high carb and sugar content) if you don't do any sort of exercise, whether that be cardio or weightlifting (or any other sort). Finally, I like that it doesn't contain any harmful stuff. This is something you would have to take every day to see results, so consuming something that is clean and sustainable is crucial. I did a lot of research on protein powders and I wanted to make sure I wasn't putting crap into my body that could be harmful long-term. Hope this helps somebody who's having questions or doubts about this.

My husband needed to gain weight. I liked the wholesome ingredients in this product so we ordered it in vanilla. My husband has split the dosage and drinks 2 scoops in 8 oz of whole milk 2 x daily. Dissolves quickly and without lumps. No need for blender. He enjoys the flavor very much. He has said that it is helping with energy levels and even some digestive issues he has had over a year! We were about out and reordered but the vanilla kept being delayed so I finally canceled and reordered. But this time the vanilla again was going to take so long so we ordered unflavored. My hubby prefers the vanilla but the unflavored is ok and he sometimes adds a vanilla flavoring. We are hoping the vanilla will be ready for faster delivery next time. Highly recommend overall.

Tastes good. Size is reasonable and I did see some gains while taking this supplement, but I stopped because it causes acne. I am not very sensitive to dairy or whey, but tapioca maltodextrin (the main ingredient and what’s used for bulking) has a glycemic index of anywhere between 85-136. Pure sugar has a glycemic index of 65. That means this product causes a significant spike in blood sugar when you take it as a meal, significantly more than straight sugar would. If you get acne from high amounts of sugar, this will cause you acne, and you might not see it for a week or two. Two potential workarounds are: taking half a serving or less post-workout ONLY, so that your muscles absorb the sugar through their now-empty glucose reserves and it skips your blood; or taking half a serving or less with two tablespoons of olive oil, avocado oil, or animal fat (tallow, cream) to slow down the glucose absorption from 15-30 mins to 1-2h (when you aren’t using it post-workout). Apart from the fact that it’s basically cleaner but harsher sugar and some good protein, I think this is a pretty decent product for gaining weight, if you’re okay with the trade-offs. You MUST use it post-workout, not pre-workout or as an extra meal, or it will likely cause you to build fat instead of muscle (since it’s sugar). It mixes and dissolves really well into cow or goat milk and tastes great in either. Kind of expensive but worth it if you have a hard time gaining weight like I do. For the time being I’m going to stop using this product since it caused be an acne outbreak, but I may continue use with my newfound workaround in the future. I just don’t think gaining weight is worth having all these spots.

I can't say enough good things about this mass gainer. I finally decided to switch to naked Mass after months of contemplation, because the natural aspect of it made me a little hesitant. I switched from Optimum Nutrition, chocolate flavor because up until now that was the only protein that had a bearable flavor in my opinion. But drinking that one made me feel so terrible for ingesting the artificial ingredients, and just felt so unhealthy consuming that in place of food. Sometimes I have a hard time eating, so I needed something natural that I could feel good about consuming when I am not able to eat food. After sometime, the ON chocolate one became so unbearably sweet and heavy that I would have a hard time finishing it and end up pouring half of it down the drain. I'm so glad I found this stuff, I got the unflavored one in hopes that I could find something that was not overly sweet but still had a delicious flavor. This protein powder is perfect because it has the calories and protein and nutrients that I need, it has only three ingredients and nothing artificial, plus it has an amazing flavor, and I actually feel good about drinking it because it only has a couple of essential ingredients and feels healthy and Light. I have been mixing it with almond milk and I'm literally obsessed.!! The unflavored one has a very very slight vanilla ice cream flavor, with only a hint of sweetness, not overwhelming at all and just perfectly balanced and creamy. I fear that I'm probably going to gain a lot with this because it just tastes so yummy and I'll be drinking it throughout the day and night :) Thank you!!

First... if you're looking to bulk up then, yes this product is better. However, very misleading on what it is. It takes 7 scoops to obtain the "serving size" and the scoops are huge. There are only 11 servings an 8 lb container. So to advertise 50grams is a misrepresentation of the product. At that right, peanutbutter could have 50 grams of protien if you consume 11 jars in a serving. So, unless ypu training to be thor in the next marvel movie, save your money, because this will just make you fat with the high caloric intake and very little protien in a realistic serving that doesn't turn into concrete.

The Naked Brand Mass Gainer has truly impressed me with its simplicity and effectiveness. In a market flooded with products loaded with additives, Naked Brand stands out for its commitment to purity and transparency. What I appreciate most about this mass gainer is its minimalist approach to ingredients. It uses simple, tried and true components that are effective in helping to gain weight quickly without unnecessary additives or fillers.

This level of transparency builds trust and confidence in the product's quality and effectiveness. Personally, I've experienced positive results with this mass gainer. It delivers on its promise to help gain weight effectively, and I've noticed improvements in muscle growth and overall strength.

I have been using this product for a few years and recently added their creatine. I went with unflavored so I can make it taste however I want. Pros: Ingredients. You do not need a bunch of worthless ingredients. This one has 3. Perfect. Amino Acids - it has all of the essential amino Acids, making it complete. Perfect. Taste: I use oat milk, banana, and strawberries. It's perfect for me to put down. Texture: I blend it using 12oz oat milk. It's has zero chalky or grainy feel. It's basically a strawberry/banana milkshake. Does it work? I gained 12 lbs pretty quickly, combined with lifting and eating other healthy meals. Cons: Serving size: 7 scoops is so much. I use 3 scoops and it still turns into 24oz, which can be a chore to drink quickly, depending on thickness. Buy this if you need to gain weight and lift. Start lower on scoops until you build up to consuming it all. It takes time to expand your stomach to include this with your other meals. I find later morning (which is when I work out) best to consume so I have room for a late lunch and dinner.
