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).

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. ## 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 (Chocolate Perfection, 5.4 kg) - Warrior Protein Shaker Bottle, Includes Wire Mixball Blender – 600ml – Perfect for Mixing Powdered Shakes, Clear, BPA Free, Dishwasher Safe - 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 --- ## 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.sn/products/648954677-instant-mass-heavyweight-mass-gainer-over-1000-kcal-per-serving](https://www.desertcart.sn/products/648954677-instant-mass-heavyweight-mass-gainer-over-1000-kcal-per-serving) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-23*
