The Most Efficient Muscle
Building Supplement
On the Market

Essential Amino Acids (EAAs) are the building blocks of protein. When properly formulated, fermented amino acids promote muscle growth, fat loss, and recovery.

At 4 calories, Fortagen delivers the highest protein nutritional value available at nearly 100%.

Fortagen is 5X more efficient than whey protein and 10X more efficient than vegan protein.

The Problem with Standard Protein Supplements

For protein synthesis to occur, all 8 essential amino acids must be present and in the correct ratio. Otherwise, the protein becomes less usable. Standard protein supplements contain imbalanced EAAs, nonessential amino acids, and high-calorie fillers.

In studies, the body was only able to utilize 18% of whey protein.1

Vegetable protein sources fared even worse at 10%.2 Wondering what happens to all that unused protein? It passes through your body as nitrogen waste.

In other words, more than 8 out of every 10 grams of protein powder is not utilized for building and repairing muscle tissue.

Switch to the Most Bioavailable Muscle Growth Supplement

Two trials tested a combination of amino acids designed for the most significant muscle-building effect. These trials showed lower nitrogen waste than had ever been previously measured.

That’s not all.

The trial that measured new muscle development versus control showed 33% greater muscle growth, all while body fat declined. 1

Studies3 also show EAA supplementation, such as Fortagen, stimulates muscle growth, even in sedentary elderly adults.

Muscle-Building Supplement

The body digests Fortagen quickly and easily. Plus, it’s fast-friendly, making it easy to hit daily protein goals without increasing caloric intake.

Dump the whey and build more muscle with Fortagen, a powerful vegan protein formula with just 4 calories per serving and a net amino acid utilization of nearly 100%.

The Best EAA Supplement

Accelerate Muscle Growth and Recovery

Don’t leave muscle gains on the table. Throw out the whey and try Fortagen, an EAA supplement scientifically engineered to grow muscle. It’s never been easier to hit your daily protein goals.

Perfect Amino Acid Profile

We created our precisely balanced amino acid formula to perfectly align with the ratio of EAAs the human body needs, resulting in the highest protein usability ever achieved.

Faster Muscle Growth

Fortagen was scientifically engineered to enable peak performance and promote lean muscle growth in the shortest time possible.

Easy to Mix and Digest

The proprietary blend of natural ingredients dissolves effortlessly in a glass of water and digests easily in your stomach.

Rapid Recovery

Increase protein synthesis naturally to prepare the body for your next workout. You’ll train harder and longer while offsetting gain-crushing muscular fatigue.

Just 4 Calories

Most protein powders have over 120 calories in a single serving. Our bloat-free, low-calorie formula won’t break a fast.

Quality Guaranteed

We will never sacrifice quality. That’s why we produce Fortagen in a US-based, FDA-registered lab to guarantee you the purest, highest quality supplements.

Superior Fasting Support

The Ultimate Fasting Protein

When training during a fast, your body still needs essential amino acids to build and repair muscle tissue. Fortagen is the perfect source for those amino acids. It won’t break your fast and serves as an appetite suppressant.

Fortagen won’t trigger an insulin response, which helps you stay energized during a fasted state and makes it easier to maintain a healthy weight.

Fermentation Protein

Pure, Fermented Amino Acids

Fortagen is built different. Whey is a byproduct of cheese production. Fortagen is a byproduct of fermentation. It was originally adapted from a cancer treatment formulated to prevent muscle wasting during chemotherapy.

Fortagen is the most bio-usable protein because it’s made up of only the essential amino acids, and in the correct proportions for building muscle. At just 4 calories, Fortagen helps you build the maximum amount of muscle while getting, and staying, as lean as possible.


Amino Acids (Ratios Optimized for Muscle Building Utility), Malic Acid, Natural Flavors, Citric Acid, Stevia Extract, Sunflower Lecithin


Mix Fortagen into 16 oz of water and blend thoroughly. Consume Fortagen as needed, preferably 30 minutes before bedtime. Take Fortagen at least 30 minutes before consuming any other protein, and more than 1 hour after consuming any other protein. There is no need to wait between Fortagen servings. For best taste, refrigerate after opening and shake before use.

Also Available With Glucose For Hyperplasia

For those following the Hyperplasia Protocol, Fortagen is also available as FortagenHP. FortagenHP combines our Fortagen essential amino acid supplement with Glucose to rapidly replenish muscle glycogen and enhance cellular hydration, promoting muscle hyperplasia.

Why glucose? When consumed immediately before your workout, glucose:

  • Rapidly absorbs into muscle fibers, promoting cellular hydration
  • Expands the muscle cells, triggering an adaptive growth response
  • Provides a quick energy boost to help fuel your X3 workouts

FortagenHP delivers glucose alongside the EAAs you need to aggressively grow muscle while fasting. As with standard Fortagen, one serving of FortagenHP is equivalent to 50g of protein from traditional sources.
