## 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).

Review: New favourite gainer! - Definitely impressed - quality mix of protein (not filled with Soy Protein like a lot of cheaper shakes do to top their macros up!) and good sources of carbs. Range of vitamins and whilst the ingredient list is long, there's not any filler in there - just a straight up good formula! Fantastic mixability, and I've noticed a few reviews online that comment about the taste - but I had the Salted Caramel one and it tastes great (obviously I can't comment on any of the other flavours, but this one has everything I need and I'll definitely be buying the bigger tub next time and trying the other flavours!) New favourite shake, reputable brand and this listing is straight from the seller so a legit product! 10/10!
Review: Good value and effective - Excellent product, good price. Other similar products I have tried have a sickly sweet synthetic flavour, more expensive and seemingly less effective. Nice taste that isn't overpowering or very sweet. Good consistency when mixed (I don't mix it very well or shake that much and the few clumps I get aren't at all off-putting) Despite the calories and well rounded ingredients I wouldn't think of this as a replacement and am pleased to see that it isn't marketed as such. Rather, if you are training or just generally busy with stuff this feels like an additional surplus/boost to improve your growth and overall health. I am not a big fan of protein powders, meal replacements, pre-workout etc and this feels like it sits somewhere nicely inbeteeen those. I would highly recommend this product to anyone that wants a well rounded powder to supplement their diet.

## 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

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

PLEASE READ so 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.
