## Overview

Reflex Nutrition Instant Mass Heavyweight is a powerhouse mass gainer delivering over 1000 calories and 60g of premium multi-source protein per serving. Enhanced with 18 essential vitamins and minerals plus creatine, it supports muscle growth, recovery, and sustained energy release. Crafted from grass-fed whey and free from added sugars and artificial additives, this blueberry-flavored formula is designed for dedicated athletes and hard gainers seeking clean, effective bulking nutrition.

## 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: The pure size of the servings needed is absurd, the serving cup itself is too large so that pouring it in the large bottles often results in it all over the floor. You would need a very big bottle with a very wide opening in order to correctly prepare this, otherwise you are met with many lumps in the drink that dont go down easy. The flavour isn't terrible but what you'd expect from a mass gainer. Please adjust the scoop to allow easier preparation.
Review: Parcel delivered opened box powder everywhere bag had split.I have tried returning this item and it says item not returnable not happy.
