Pack on Lean Muscle not Fat!

Muscle-XGF is a potent mass gaining formula designed for solid lean muscle growth without fat gain.

Typical weight gainers get their calories mostly from cheap carbohydrates. Excessive carbohydrates only provide "empty" calories. The weight you gain from these sub par products is mostly fat. Gaining lean muscle mass is more than just slamming "empty" calories. That's why Muscle-XGF delivers you a precision formulation designed to support solid, lean mass weight gain, without adding fat.


MyoGen-8 is our new multi-release 8-stage nitrogen-rich protein hybrid- consisting of 8 precision coalesced protein composites designed for slow, medium, and fast nitrogen delivery. You get fast and long lasting nitrogen delivery for immediate and extended protein synthesis. No other weight gainer gives you such a comprehensive protein formula.

Thermo-Lipid Complex

Muscle-XGF is formulated with a special thermogenic lipid complex that provides your body with fuel for intense energy and thermogenic calories that support fat burning to make you leaner. Rich in CLA, Omega-3 and Omega-6 fatty acids, Muscle-XGF delivers the performance and benefits of engineered lipids to support vital hormone production and help promote optimal health.

Ultra-low in Carbohydrates

New Muscle-XGF has redefined the weight gainer category. It's ultra low in carbohydrates, but high in protein and nutrient dense, muscle-building calories. Muscle-XGF is designed for the typical "hard gainer" - those who have a hard time gaining weight and who want rapid gains in lean muscle growth. Muscle-XGF gives you constructive, dense calories while at the same time eliminating excessive carbohydrate intake and fat gain.

Integrated ATP Support System

Each serving of Muscle-XGF supplies 3 grams of pure micronized creatine monohydrate and ATP co-factors for research proven dynamic muscle and strength gains and muscle creatine saturation.

BCAAs and L-Leucine

Muscle-XGF also supplies abundant amounts of BCAAs and free L-Leucine with each serving that are critical to anabolic and anti-catabolic processes.

The World's Strongest Weight Gainer

Pound for pound, ounce for ounce, gram for gram, Muscle-XGF is the most powerful weight gainer in the world! It taste like gourmet milkshake and supplies all the critical nutrients for supporting fast muscle growth. Each glass provides a hefty caloric punch without giving you that bloated, overly full feeling.

Suggested Use

Muscle-XGF can be taken anytime you want to add muscle building protein and calories to your diet. Add 2 scoops to 10-12 ounces of cold water. For an even richer and better tasting shake add 2 scoops to 16 ounces of cold skim or whole milk. The rich delicious taste will blow you away.


A Muscle-XGF shake is perfect for a muscle building breakfast shake and even better when added to a nutritious breakfast.


For high energy and to flood your muscles with growth promoting nutrients have a Muscle-XGF shake 1 hour before you workout.


A Muscle-XGF shake is perfect 1 hour after your workout to supply a steady stream of protein and amino acids to hungry muscles.


A Muscle-XGF shake before bedtime slams the door on muscle robbing catabolism. It supplies a long-lasting supply of precision nutrients for night-time muscle growth support.
