With over 1000 calories per shake, this bulking protein powder formula fuels your body with substantial quantities of macronutrients for building and maintaining muscle mass. Our protien blend combines four premium sources of whey protein with slow-releasing micellar casein, catering to both immediate and sustained amino acid delivery.

Together with Native Whey, these form a full-spectrum protein assault that contributes effectively to muscle growth and recovery.

This intelligent carb blend sidesteps the pitfalls of simple sugars and syrups, opting instead for a sustained-release energy supply - It's the perfect partner for the long, intense workout sessions.

Box Contains 1 x 2kg container Manufacturer Contact Information Reflex Nutrition, Sea View Way, Brighton, BN2 6NT, UK Review: 100 percent works 100 percent tastes great - best protein shake I've tried by far, the chocolate flavour isn't to intense and the texture isn't to thick, blends up very nicely 100 percent would recommend for people that have problems finding a nice flavour or thickness, this one sits just right bang on will only be buying this from now on and you cant complain at that price its an absolute steal product does what it says and tastes great whilst doing its job Review: Amaaazing, I need to stock up. Helps me gain weight. Best one yet! Highly recommend. - This drink is soo good omg I love how high the calorie intake is, it’s over 1,000 calories I’ve lost weight due to a stupid toxic relationship I’m exiting and was struggling to keep up the daily calorie intake. Now this drink here with a work out after is doing me right lol. It gives me more of an appetite aswell come lunch time and just throughout the day. So I’ll drink one a day in the morning 5 scoops and I use oat milk and some crushed ice tiny scoop of brown sugar (blended until smooth) amazing. Sometimes i bulk it out more by adding a whole banana, a spoonful of peanut butter and a tablespoon of porridge oats. yum. Tried it with water as suggested and really wasn’t for me, flavour wise. Not great. Will definitely be ordering more. (edit I'm on my 7th tub lol) Only downside is when you open the tub lol liiiike who’s been at this already. Looking like half’s missing smh but I guess the content amount is stated in the description, just don’t get the need for such a big tub. Its misleading. ****** 26th July 24 so this is the first tub I’ve had that hasn’t come with a blue measuring cup. Not great because I like it to be precise. I’ll have to buy a small jar / cup that holds the equivalent of what the blue measuring cup would. Not good. ## Features - Engineered for Gains: This seamless protein shake mix is specifically formulated to accelerate muscle and weight gains and improve post-workout recovery, enhancing overall workout performance for the dedicated, hard gainer and serious athlete alike - Excellent Nutrition Profile: Packed with quality ingredients, each protein shake serving delivers over 1000 kcals, 200g of complex carbohydrates, 60g of muscle gain protein, critical EAAs, creatine, 18 vitamins and minerals (B12, B6, C, Iron, Zinc) - Outstanding Taste Sensation: Our Chocolate Perfection mass gainer flavour isn't just a treat for your taste buds - it's a deliciously creamy escape into indulgence with every sip, all while you are fueling your body for mass gain and muscle recovery - Optimal Timing for Maximum Impact: Consume Instant Mass Heavyweight high protein shake between meals for a positive nitrogen balance, 20-30 minutes post workout for best results or 45-60 minutes before sleep to aid overnight muscle maintenance - Trusted Quality Assurance: Reflex Nutrition's promise to quality means whey protein powder from grass-fed cows - Protein Sources are Glutamine Peptides, Whey Protein Concentrate, Milk Protein, Hydrolysed Whey Protein - Produced in an Informed Sport Registered Facility - Suitable for vegetarians and Halal certified - Zero added sugars, artificial colors, or soy protein, assuring a conscientious choice of weight gainer for your muscle-building objectives ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E483MDK | | Age Range Description | Adult | | Allergen Information | Contains: Egg may contain, Milk, Oat, Soy, Wheat | | Benefits | Muscle Growth | | Best Sellers Rank | 2,584 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 31 in Protein Nutrition Blends 61 in Diet Shakes | | Brand | Reflex Nutrition | | Brand Name | Reflex Nutrition | | Country Of Origin | United Kingdom | | Customer Reviews | 4.1 out of 5 stars 657 Reviews | | Diet Type | Halal | | Diet type | Halal | | Flavour | Chocolate | | Global Trade Identification Number | 05033579001500 | | Item Dimensions | 20 x 20 x 26 centimetres | | Item Nype Name | HEALTH_PERSONAL_CARE | | Item Weight | 2000 Grams | | Item weight | 2000 Grams | | Manufacturer | Reflex Nutrition Ltd | | Manufacturer Contact Information | Reflex Nutrition, Sea View Way, Brighton, BN2 6NT, UK | | Manufacturer Part Number | 100044200030 | | Material Type Free | Caffeine Free, GMO Free | | Model Name | Reflex Nutrition Instant Mass Heavyweight | Mass Protein Powder | | Model Number | Instant Mass Heavyweight Protein | | Net Content Volume | 10.4 Litres | | Number of Items | 1 | | Package Type Name | Tub | | Product benefits | Muscle Growth | | Protein | 60 g | | Protein Source | Whey | | Recommended Uses For Product | During Workout, Post-Workout, Pre-Workout | | Supplement Formulation | Multi-Supplement | | Unit Count | 2000.0 gram | ## Product Details - **Brand:** Reflex Nutrition - **Diet type:** Halal - **Flavour:** Chocolate - **Item weight:** 2000 Grams - **Material Type Free:** Caffeine Free, GMO Free - **Number of items:** 1 - **Product benefits:** Muscle Growth - **Protein source:** Whey - **Recommended uses for product:** During Workout, Post-Workout, Pre-Workout - **Unit count:** 2000.0 gram ## Images ![Reflex Instant Mass Heavyweight Mass Gainer Protein, Chocolate, 2kg - Image 1](https://m.media-amazon.com/images/I/716TgeMLFAL.jpg) ![Reflex Instant Mass Heavyweight Mass Gainer Protein, Chocolate, 2kg - Image 2](https://m.media-amazon.com/images/I/71CS32jb-pL.jpg) ![Reflex Instant Mass Heavyweight Mass Gainer Protein, Chocolate, 2kg - Image 3](https://m.media-amazon.com/images/I/71jH3uQln4L.jpg) ![Reflex Instant Mass Heavyweight Mass Gainer Protein, Chocolate, 2kg - Image 4](https://m.media-amazon.com/images/I/71Wg1XbqJRL.jpg) ![Reflex Instant Mass Heavyweight Mass Gainer Protein, Chocolate, 2kg - Image 5](https://m.media-amazon.com/images/I/714PsAbesZL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: Why isnt the nutritional info shown?!** A: The company sent me only half my order on multiple occasions and the wrong flavour. The fact that the nutritional info isnton there is no surprise **Q: how well does this mix in an ordinary shaker? i know some are clumpy and chalky tasting, thank you** A: Hi I would recommend blend for 7 seconds if that. If you have a good shaker and give it a good shake it will be just as smooth great mix chocolate for me taste wonderful **Q: Has it got any. Bcaa,s pls** A: Finished it a long time ago so don’t have the package. But i checked the photos and googled the BCAA’s and based on this, the product doesn’t have any of the 9 essential amino acids aka BCAA. So it’s a No and you’ll have to buy it separately. **Q: Must I work out to use this?** A: I won't buy this again as found the taste not to my liking at all as for working out I would as I belive this will help you gain weight but mostly on the stomach if you don't work out ## Customer Reviews ### ⭐⭐⭐⭐⭐ 100 percent works 100 percent tastes great *by C***D on 12 March 2026* best protein shake I've tried by far, the chocolate flavour isn't to intense and the texture isn't to thick, blends up very nicely 100 percent would recommend for people that have problems finding a nice flavour or thickness, this one sits just right bang on will only be buying this from now on and you cant complain at that price its an absolute steal product does what it says and tastes great whilst doing its job ### ⭐⭐⭐⭐⭐ Amaaazing, I need to stock up.
