## 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: 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.
Review: Excellent - I bought this for my son who is not a gym lover but is a manual worker (Plaster/ builder) who finds it very hard to keep wieght about him, he finds this keeps him healthy with a good gut, it is very good value for money smooth when made up with a nice flavour. I will be buying again

## 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

I bought this for my son who is not a gym lover but is a manual worker (Plaster/ builder) who finds it very hard to keep wieght about him, he finds this keeps him healthy with a good gut, it is very good value for money smooth when made up with a nice flavour. I will be buying again

### ⭐⭐⭐⭐ It's very effective
*by N***O on 5 January 2026*

It's effective but it's not magic. You have to be consistent with it. I added extra weight which I wanted, after a few weeks. Prompt delivery. Well sealed. The protein quality is good. I mix mine with milk. It doesn't upset my tummy. It has a good taste. The only reason I didn't rate it 5 star is the packaging.
