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. The Whey Protein Concentrate is carefully processed to preserve its purity, while Hydrolysed Whey Protein is enzymatically treated for rapid absorption. Together with Native Whey, these form a full-spectrum protein assault that contributes effectively to muscle growth and recovery. Instant Mass Heavyweight bodybulding supplement is crafted with a multifaceted carbohydrate matrix. 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. Each serving of protein supplements is also power-packed with 18 added vitamins and minerals, amplifying the nutrition profile and supporting your body’s demands through all phases of training - whether you’re prepping, pushing through, or in post-workout recovery, Reflex's weight gain protein powder formula will help you achieve your goals. Incorporated into this mix is creatine powder, scientifically proven to increase physical performance in successive bursts of short-term, high-intensity exercise, ideal for those aiming to dominate in their sport. This high protein shake is available in two sizes to accommodate your training intensity and frequency (protein powder 2kg and protein powder 5.4kg).

Box Contains 1 x Instant Mass Heavyweight - 5.4kg - Vanilla Ice Cream Manufacturer Contact Information Reflex Nutrition, Sea View Way, Brighton, BN2 6NT, UK Review: Great product. - Not a food person in the morning so this works great. Good taste and mixes well. Not gritty, good value and feel much better after a few weeks. Can't comment on gym use as I don't go. Review: Tasty, helps put on weight and mixes well - Husband loves this! He has purchased this 3 times now, uses it in between meals and on days where he’s out for work and doesn’t have time to grab something to eat. It’s been great for helping him put on weight. Really lovely flavour and mixes well with water or milk, unlike other reputable protein shakes that have a strange after taste and texture. The 5kg bag lasts a while, so definitely worth it and it comes in an easily resealable bag with a scoop. Only down side is the sugar content is very high! Also the recently price went up, which is a shame as had bought it around £28 couple months ago. ## 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 Vanilla Ice-Cream 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 | B00KAB0LJ4 | | Age Range Description | Adult | | Allergen Information | Contains: Egg may contain, Milk, Oat, Soy, Wheat | | Benefits | Muscle Growth | | Best Sellers Rank | 1,138 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 36 in Whey Nutrition Protein | | Brand | Reflex | | Brand Name | Reflex | | Country Of Origin | United Kingdom | | Customer Reviews | 4.0 out of 5 stars 1,875 Reviews | | Diet Type | Halal | | Diet type | Halal | | Flavour | Vanilla | | Global Trade Identification Number | 05033579001401 | | Item Dimensions | 39 x 14 x 52 centimetres | | Item Nype Name | HEALTH_PERSONAL_CARE | | Item Weight | 5400 Grams | | Item weight | 5400 Grams | | Manufacturer | Reflex Nutrition | | Manufacturer Contact Information | Reflex Nutrition, Sea View Way, Brighton, BN2 6NT, UK | | Material Type Free | Caffeine Free, GMO Free | | Number of Items | 1 | | Package Type Name | Tub | | Product benefits | Muscle Growth | | Protein | 60 g | | Protein Source | Whey | | Recommended Uses For Product | Post-Workout | | Supplement Formulation | Multi-Supplement | | Unit Count | 5400.0 gram | ## Product Details - **Brand:** Reflex - **Diet type:** Halal - **Flavour:** Vanilla - **Item weight:** 5400 Grams - **Material Type Free:** Caffeine Free, GMO Free - **Number of items:** 1 - **Product benefits:** Muscle Growth - **Protein source:** Whey - **Recommended uses for product:** Post-Workout - **Unit count:** 5400.0 gram ## Images ![Reflex Nutrition Instant Mass Heavyweight - Mass Gainer - Over 1000 Kcal per Serving, 60g Protein, Creatine - High Calorie Post Workout or Before Bed Protein Shake (Vanilla Ice-Cream, 5.4 kg) - Image 1](https://m.media-amazon.com/images/I/71r8VHTCaSL.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: Good afternoon. is this the original reflex supplement. why is there a big difference in the price. why on amazon it is soo much cheaper** A: Good afternoon So basically if you want to sell something on a website like Amazon your price should be lower then the price you might sell individually by yourself, plus, Amazon and similar websites make profit by the quantity of the products being sold not individually that’s why they can break the price that low cause obviously they buy it for a low price in mass quantities. Even with the suppliers if you make a deal to buy a good amount of their products, you can get a good discount. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by C***S on 19 February 2026* Not a food person in the morning so this works great. Good taste and mixes well. Not gritty, good value and feel much better after a few weeks. Can't comment on gym use as I don't go. ### ⭐⭐⭐⭐⭐ Tasty, helps put on weight and mixes well *by S***M on 23 January 2026* Husband loves this! He has purchased this 3 times now, uses it in between meals and on days where he’s out for work and doesn’t have time to grab something to eat. It’s been great for helping him put on weight. Really lovely flavour and mixes well with water or milk, unlike other reputable protein shakes that have a strange after taste and texture.

Also the recently price went up, which is a shame as had bought it around £28 couple months ago. ### ⭐⭐⭐⭐ Decent stuff *by B***N on 4 January 2024* Just starting off at the gym again trying to bulk and this definitely has helped, it's impossible to get a full serving into one shaker so I have to do it in 2. This isn't a milkshake from your local restaurant so don't expect it to be tasting like so. Taste isn't the greatest but definitely isn't the worst. But I'm not using it for taste so it is what it is. I've put on around 8/9lbs since using it over the past couple months (had a period where I stopped using it) if new to this then start off with half the full serving for the first week as going all in with a full one can cause stomach problems (bloating, wind, nausea etc) im taking along side cyclone, at different intervals, obviously, and also only using cyclone every other day. It's not no miracle shake, so don't expect unrealistic results, eating a full breakfast, lunch, dinner and snacks in between then this and hour or so before bed has worked for me. Can't really say if it works for performance as I'm still figuring that out myself. Will update once I know more but so far so good. ## Frequently Bought Together - Reflex Nutrition Instant Mass Heavyweight - Mass Gainer - Over 1000 Kcal per Serving, 60g Protein, Creatine - High Calorie Post Workout or Before Bed Protein Shake (Vanilla Ice-Cream, 5.4 kg) - Bulk Iconic Shaker Bottle, 750ml, Clear, Leak-Proof, BPA-Free, Wire Mixing Ball for Lump-Free Shakes, Convenient Carry Handle, Transparent Fill Level, Dishwasher Safe - Warrior Protein Shaker Bottle, Includes Wire Mixball Blender – 600ml – Perfect for Mixing Powdered Shakes, Clear, BPA Free, Dishwasher Safe --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/53918824-reflex-nutrition-instant-mass-heavyweight-mass-gainer-over-1000-kcal](https://www.desertcart.com.cy/products/53918824-reflex-nutrition-instant-mass-heavyweight-mass-gainer-over-1000-kcal) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
