Lean Mass Gainer

A more measured way to load up throughout the day. This precise mass gain formula for trainers who want to build muscle mass in a controlled manner. Each 85g serving contains 328kcal, comprising 34g of protein, 34g of carbohydrate and under 6g of fat. If you want to bulk up, you’ve got to pack in the calories, but some people might want to take a more steady approach. This Lean Mass Gainer formula provides all the protein you need. The ingredients in Lean Mass Gainer are carefully sourced to provide the nutrition you need in careful measure. The protein is sourced from a combination of whey protein concentrate, milk protein concentrate and egg white powder, meaning you get a mix of fast and slow release proteins, and the carbohydrates come from ultra fine Scottish oats. On top of that, we’ve even added glutamine peptides.

The Purpose

We designed our Lean Mass Gainer for trainers who want to increase their muscle mass without necessarily piling in the carbs. Each serving’s 328kcal calorie content places it perfectly between a typical protein shake and traditional mass gainers, which usually contain over 500kcals per serving. If you think you need a more serious mass gain powder, check out our Mass Gainer formula.
