Description

Gaining significant weight requires a high calorie intake, yet many individuals who need those extra calories find it difficult to eat enough. For those looking to build a larger physique, factors such as a fast metabolism, reduced appetite, and a busy lifestyle can make it hard to meet calorie requirements through whole foods alone. That’s where Serious Mass comes in as the ultimate weight-gain solution.

Each serving provides a robust 1,250 calories to increase your daily intake, along with 50g of premium protein to aid muscle growth and repair, over 250g of carbohydrates for effective muscle recovery, and now features 3g of added Creatine to enhance performance, all in a delicious vanilla flavour. It’s time to stop thinking small and get serious about your gains!

Storage and Prep
After opening close tightly. Store in a cool and dark place. For batch code/best before end: see packaging. Mix 2 heaped scoops with 710 ml of water. You can also add a serving to smoothies, protein balls, muffins, porridge or other meals as another great way to get a protein hit in the kitchen. For best results, consume your shake between meals when you need extra calories throughout your day or after you work out to support recovery*. To be used in the framework of a varied and balanced diet and healthy lifestyle. Tip: New users may find it beneficial to begin with a 1/2 serving (1 scoop), gradually increasing to a full (2 scoop) serving. *Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.
