Muscle Growth Unleashed.

FST-450 is a natural anabolic designed to increase lean muscle mass, enhance protein synthesis, inhibit myostatin, and maximize follistatin production.

The Science

Combining Phosphatidic Acid (PA) and Epicatechin in ideal ratios provides a powerful synergistic effect that delivers maximum muscle building results.

Phosphatidic Acid (PA)
Mediator® Phosphatidic Acid (PA) was demonstrated in a university study to provide double the muscle mass gain in subjects engaged in weight bearing exercise and who consumed adequate protein.

Orally ingested Phosphatidic Acid (PA), when accompanied with mechanical stress on muscle and adequate protein intake, significantly activates the Mammalian Target of Rapamycin (mTOR) signaling pathway. Scientists believe that mTOR is necessary for mechanical load-induced growth of skeletal muscle (muscular hypertrophy) and consequent strength gain. mTOR regulates protein synthesis, whereby ingested protein is translated into new muscle.

Research has shown that Epicatechin can enhance muscle growth by increasing follistatin and decreasing myostatin. Follistatin, a powerful anabolic, supports muscle growth by inhibiting myostatin signaling. Myostatin, considered the "muscle building OFF switch", is a muscle growth regulator. The more Follistatin present, the more muscle that will be built.

Naturally occurring in cocoa extract, Epicatechin is an incredibly intriguing flavonol that offers a wealth of benefits for animals that need to increase muscle mass and improve body composition.


  • Accelerates muscle growth
  • Increases strength
  • Enhances nitric oxide production
  • improves glucose tolerance
  • Boosts endurance
  • Reduces fatigue


1-3 capsules daily with protein-rich food.
Dosages can vary depending on animal size, weight, etc. Only give FST-450 to your animal as directed by a veterinary professional.

Please note: FST-450 should be administered once the animal is near the end of their injury recovery or has fully recovered. Excessive muscle growth should be avoided during the early stages of injury recovery.


Each capsule contains 350mg of Mediator® Phosphatidic Acid (PA) and 100mg of Epicatechin 90%.
