Unlock Your Genetic Potential

The Future of Strength, Longevity, and Cellular Renewal.

Why Follistatin Matters

At Xtend Cells, we are proud to be one of only three official global partners authorized to provide Follistatin Gene Therapy (FST-344) using minicircle DNA technology.

This groundbreaking therapy elevates your body’s natural production of follistatin, a key protein that blocks myostatin and activin — unlocking your innate capacity to:
 
  • Build lean muscle mass
  • Reduce fat levels
  • Reverse markers of biological aging
  • Accelerate cellular recovery and regeneration

How It Works

  • Cutting-edge delivery: Follistatin is expressed via a simple subcutaneous injection using advanced minicircle plasmids — no surgery, no permanent DNA alteration.
  • Cellular optimization: By reducing the activity of myostatin, your body is free to increase muscle growth, decrease inflammation, and enhance recovery.
  • Biological age reset: Clinical studies show an average reduction of 7 years in epigenetic age, with some cases reaching nearly 28 years younger.

Expected Benefits

  • Increased lean muscle and strength

  • Reduced body fat percentage

  • Reversal of biological age markers

  • Enhanced vitality and energy levels

  • Faster recovery and improved resilience

Safety & Clinical Insights

  • Early clinical data confirms excellent tolerability and safety.
  • Mild side effects have been reported (e.g., slight increases in LDL cholesterol in some participants) but remain manageable with lifestyle optimization.
  • Not recommended for individuals who are pregnant or planning pregnancy within the next year.

Frequently Asked Questions (FAQs)

Unlike temporary hormone therapies or invasive stem cell procedures, FST-344 reprograms your biology at the genetic expression level — without altering your DNA — offering longer-lasting, more profound results.

How is Follistatin Gene Therapy different from traditional stem cell or hormone treatments?

No. The effects typically last around 12 months. Many clients choose annual re-administration to sustain results.

Is the therapy permanent?

Most clients report feeling the difference within the first 30 days, with peak improvements between months 3 and 11.

How soon will I notice changes?

Clinical studies to date show high tolerability and no serious adverse events. Mild side effects, such as slight changes in lipid profiles, may occur but are manageable.

Is it safe?

FST-344 is administered exclusively at authorized international partner clinics. Xtend Cells is one of only three official providers worldwide.

Where is the therapy performed?

Individuals who are pregnant or planning to become pregnant within the next year should not pursue this treatment.
