Designed for Quality, Not Just Quantity

Unlike typical gainers loaded with sugar and low-grade ingredients, Clean Gainer focuses on clean growth. Each serving delivers a perfect balance of macronutrients to help you:

• Increase lean muscle mass

• Improve recovery and endurance

• Support calorie intake with real food-based nutrients

• Avoid bloating and unnecessary fat gain

Whether you’re bulking up for a season, recovering from intense training, or just need extra calories to meet your goals, this is the smart, effective way to grow.

Protein That Powers Growth

Every serving of Clean Gainer contains 30 grams of high-quality, complete protein sourced from:

• Whey Protein Concentrate

• Whey Protein Isolate

• Milk Protein Isolate

• Micellar Casein

This combination provides a fast and slow-digesting protein matrix, ideal for muscle repair, strength, and growth. It ensures a steady stream of amino acids — including naturally occurring BCAAs — to fuel anabolic processes both immediately post-workout and for hours after.

Amino acids are naturally occurring and values are approximated. Information varies by flavor. Refer to nutritional, ingredient, and allergen information for complete details.

INSIGHTS

To pack on serious size, you need to consume more energy than you burn. A number of variables need to be factored in, but 3,500 calories per pound of added body weight is a commonly referenced estimate. True hard gainers may need even more. In a world of fast food, finding extra calories isn’t hard. Getting quality, protein-rich calories to back-up your gym time? Now that’s a different story.

With a killer combo of full-spectrum proteins, eight energizing carb sources, and essential fats, CLEAN GAINER™ is high-octane nutrition (over 560 calories worth) that fuels the intense needs of world-class athletes as well as those who aspire to be. Factor in the no banned substances and it’s a MASSIVE winner.

Complex Carbohydrates for Energy and Recovery

With 97 grams of carbohydrates per serving, Clean Gainer fuels your workouts and supports recovery the right way. Unlike gainers that spike blood sugar with simple sugars, this formula features a complex carbohydrate blend including:

• Quinoa

• Brown Rice

• Oats

• Sweet Potato

These low-GI carbs provide sustained energy, glycogen replenishment, and help prevent sugar crashes — ideal for performance athletes and active individuals who demand more from their nutrition.

Healthy Fats for Hormonal Support and Recovery

Fat isn’t the enemy — especially when it comes from quality sources. Clean Gainer includes 8 grams of good fats from:

• Avocado powder

• Flaxseed

• Sunflower oil

• MCTs (medium-chain triglycerides)

These fats support hormone health, cognitive function, and energy production, all of which are essential for athletic recovery and growth. Plus, they help give Clean Gainer its ultra-smooth, rich texture.

Nutrient-Rich, Not Sugar-Loaded

Many gainers use sugar as a shortcut to inflate calorie counts. Not here. Clean Gainer contains only 8g of sugar per serving, making it an excellent option for those looking to bulk clean. This controlled sugar content ensures your weight gain is driven by muscle, not unwanted fat.

Smooth, Delicious, and Easy to Digest

The clean formula is also:

• Gluten-Free

• Banned Substance Tested

• Made in a GMP-compliant facility

It’s designed to be easy on the stomach, so you can take multiple servings daily without bloating or discomfort.
