## Description

Product Description               Reflex Nutrition’s Instant Mass Heavyweight protein powder is developed for hard gainers and athletes seeking a quality blend of proteins and complex carbohydrates. 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).  Choose your flavour from a variety including traditional favourites and exciting new taste profiles (vanilla protein powder, strawberry protein powder, chocolate protein powder and more).

## Customer Reviews

### ⭐⭐⭐⭐⭐ 100/100  ⭐️⭐️⭐️⭐️⭐️
*by V***  on 17 June 2025*

Absolutely amazing! I usually can’t tolerate sweet flavors and drinking most protein shakes is a real struggle for me: they’re often too sweet and make me feel sick. Was I looking for a protein shake? Yes, and I’ve finally found the perfect one.FYI: The protein powder dissolves very well in water and I ordered the blueberry flavour, which is pleasantly mild and not overpowering. I really like it! I even blend in some frozen blueberries for an extra touch and it mixes beautifully.The result is absolutely amazing, no excessive sweetness, easy to drink, and no discomfort afterwards.

### ⭐⭐⭐⭐⭐ Tastes great no crappy aftertaste
*by A***N on 7 June 2025*

Just bought this Strawberry and CreamFirst of all it smells amazing .I'm getting old (55) and I'm an extremely busy person ... i don't go to the gym never have never will and bought this as additional calorie intake.1st impressions .... you will need a massive shaker to fit in a full serving .I ended up doing 1/2 serving with 500ml of water twice.It mixes absolutely fine with no clumping ( I did only add a little at a time to the water )Tastes absolutely fine with no crappy after taste .No complaints

### ⭐⭐⭐⭐ Please read review. Nice taste and mix but questionable ingredients
*by J***S on 7 May 2025*

PLEASE READso as a weight gainer shake , mixability and taste wise I think it's great.Unfortunately the main ingredient is maltodextrin . Which they say is a carbohydrate source , but in fact your body sees this more like a sugar and this spikes your blood sugar way more than table sugar. In fact almost double.This item for that reason will help you gain weight , but I doubt much of it would be muscle.I've given 4 stars because it's not bad , but if you are informed on ingredients you will understand maltodextrin is one you are best to avoid.Dr Berg does an interesting video on it if anyone would like a dr's opinion.
