  • 5x more efficient than standard protein sources
  • Perfect protein for intermittent fasting—only 4 calories
  • For those looking to rapidly replenish muscle glycogen and enhance cellular hydration and still get the proven results of Fortagen, learn about FortagenHP.

The Most Efficient Muscle-Building Supplement for Lean Muscle Growth

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%.

Just 10g of Fortagen provides as much usable protein as 50g of whey.

The Problem With Standard Protein Supplements

For protein synthesis to occur, all 8 essential amino acids (EAAs) 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, just 18% of whey protein was utilized by the body.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.

The Problem with Standard Protein Supplements

Switch to the Most Bioavailable Muscle Growth Supplement

In two trials, a combination of amino acids designed for the greatest muscle-building effect were tested. The 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 show EAA supplementation stimulates muscle protein anabolism (muscle growth), even in sedentary elderly adults. The contribution of EAAs in the proper ratios to muscle synthesis cannot be overstated.

Accelerate Muscle Growth and Recovery

Don’t leave muscle gains on the table. Fortagen is an aminos powder supplement scientifically engineered to grow muscle. It’s never been easier to hit your daily protein intake, lose weight, and accelerate muscle growth.

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 utility for protein building.

Faster Muscle Growth

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

Easy to Mix and Digest

Fortagen is digested in under 30 minutes. The proprietary blend of natural ingredients mixes with water in seconds 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 formula is only 4 calories, which won’t break a fast.

Quality Guaranteed

Fortagen is fermented, mixed, and packaged 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. Fortagen will not break your fast and also 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.

Faster Lean Muscle Growth From A Better Protein

Why We Created Fortagen

Fermentation Protein

Pure, Fermented Amino Acids

Whey protein is a byproduct of cheese production. These highly processed, bloat-inducing supplements are packed with unusable proteins and unnecessary calories. Aside from amino acids, Fortagen contains just 5 all-natural, vegan-friendly ingredients.

Fortagen provides the most effective ratios of the eight essential amino acids your body needs to synthesize protein and build muscle without all that waste.


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.
