Premium Mass Gainer

High Quality weight gainer with 45g protein per serving
Muscle building Creatine, Leucine, Glutamine & HMB
Whey Protein Isolate, Oats, MCT & Flaxseed


We believe that INFORMED MASS® is not only the best mass gainer in Europe – but the world.

We understand that this is a bold statement – but we really mean it. In fact, if you purchase INFORMED MASS® and are not entirely happy with it, we will refund you!* As far as we are aware, INFORMED MASS® is the only weight gain supplement to come with this money-back guarantee.

When formulating INFORMED MASS®, our team of expert nutritionists were tasked with creating the most comprehensive mass gainer available. It also had to offer better value for money than the competition – and taste better too. This involved analysing the market-leading products and simply making them better. After months of research and hundreds of formulations, INFORMED MASS® was born.

The starting point for INFORMED MASS® was to make sure it was packed with quality sources of protein, carbohydrates, good fats and muscle-building nutrients. With 45g protein (derived primarily from high quality European Whey Protein Isolate), almost 75g slow-release carbohydrates from premium Scottish Oats, 10g healthy fats from Medium Chain Triglycerides and Flaxseed Powder, plus the addition of 5g Creatine Monohydrate, 5g Leucine, 3g Glutamine Peptides, 1.5g HMB, 40mg DigeZyme® and 100,000,000 Probiotic spores (from LactoSpore®) per serving – it is clear to see why INFORMED MASS® has quickly gained a reputation as the market-leading mass gainer.

For added reassurance, INFORMED MASS®  has been randomly drug screened at a renowned anti-doping laboratory.

A serving of INFORMED MASS® contains the following:

mTOR Protein Complex™: Contains Whey Protein Isolate as the primary protein source (65%) and Whey Protein Concentrate as the secondary protein source (35%). The mTOR Protein Complex™ also contains 5g Leucine; an important amino acid for stimulating protein synthesis and therefore muscle growth.

Instant Oats: The benefits of Oats are well documented. Oats provide a sustained release of energy and are considered the most ‘healthy’ and nutrient rich carbohydrate source available.

Creatine Monohydrate: Creatine is the most researched sports supplement available today. Research consistently shows increases in muscle size and strength with Creatine supplementation.

HMB: Recent research on HMB has reinforced some of the original HMB research. While HMB is a metabolite of Leucine, research suggests there may be a synergistic benefit of using HMB and Leucine together. While Leucine plays an important role in the signalling process for protein synthesis, HMB reduces muscle breakdown.

Glutamine Peptides: Glutamine is the most abundant amino acid in muscle, and is often depleted by hard training. INFORMED MASS® contains an impressive 3g Glutamine Peptides per serving to help replenish Glutamine levels.

Medium Chain Triglycerides (MCTs): Medium Chain Triglycerides provide a quality, calorie dense energy source and are also very easily digested, reducing potential gastric discomfort.

Flaxseed Powder: Flaxseed adds a high quality source of essential fatty acids (EFA) and fibre to INFORMED MASS®.

DigeZyme®: A blend of: Amylase, Protease, Cellulase, Lactase and Lipase. These 5 digestive enzymes combine to aid the digestion and breakdown of protein, carbohydrate, fat and lactose. This improves digestive health and ensures maximum absorption of other nutrients within INFORMED MASS®.

LactoSpore®: A high quality, superior probiotic documented to support the immune system, digestive system and general health.
