Follistatin-344 (FST-344)

Zuletzt aktualisiert: März 2026

Sequenz: 344 amino acids (protein)Herkunft: Recombinant human follistatin

Wichtigste Eigenschaften

Inhibits myostatin (muscle growth limiter)
May support muscle growth beyond natural limits
Studied for muscle wasting conditions
Potential fertility applications

Wirkungsweise

Follistatin-344 is a recombinant form of human follistatin, a glycoprotein that binds and neutralizes myostatin — the protein that limits muscle growth. By inhibiting myostatin and activin signaling, follistatin removes the natural brake on muscle hypertrophy. It has been extensively studied in gene therapy trials for muscular dystrophy and muscle wasting conditions.

Forschungsergebnisse

  • Binds and neutralizes myostatin (muscle growth inhibitor)
  • Gene therapy trials for Becker muscular dystrophy showed muscle improvements
  • Animal studies showed dramatic muscle hypertrophy
  • Also inhibits activin, affecting FSH and reproductive function
  • Multiple isoforms exist (315, 344, 288) with different tissue distributions

Verfügbare Formen

  • Lyophilized powder for injection

Typische Forschungsdosierung

Research protocols typically use 100mcg-1mg subcutaneous. Due to its large size and cost, careful dosing is important. Short cycling protocols are common.
