Lean Mass Gainer

A more measured way to load up throughout the day. This precise mass gain formula has a lower carb content for trainers who want to build muscle mass in a controlled manner. Each 85g serving packs in 338kcal, comprising 34g of protein, 34g of carbohydrate and just 5g 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 but with a lower Carb content than typical mass gainers, giving you greater control over your calorie intake.

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.

Disclaimer: Implied results may vary. Individuals will respond differently. Implied results assume an appropriate nutrition and training plan.

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 338kcal 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.


Mix 3 scoops (approximately 85g) Lean Mass Gainer with 350ml water in a Bulk™ Shaker Bottle. Use 1-3 servings per day. Common times include: breakfast, mid-morning, mid-afternoon and before bed.
