Follistatin-344

Full name
Follistatin-344
Mechanism
Glycoprotein that binds and neutralises myostatin (and other TGF-beta family members), removing the brake on muscle growth in preclinical models.

subcutaneous/intramuscular (anecdotal, unvalidated)
Typical dosage*
low: research-defined · typical: no established safe human dose · high: unknown
Researched for
muscle-growth / muscular-dystrophy research (preclinical/gene-therapy context)
Reported side effects
no human safety data for injected peptide, theoretical: off-target TGF-beta effects
Interactions

Commonly combined
experimental anabolic protocols (anecdotal, high-uncertainty)
Scheduling
🇦🇺 AUNot ARTG-registered; research
🇺🇸 USNot FDA-approved

Questions (9)

What is Follistatin-344?

Follistatin-344 (Follistatin-344). Glycoprotein that binds and neutralises myostatin (and other TGF-beta family members), removing the brake on muscle growth in preclinical models.

What is Follistatin-344 used for?

Commonly discussed uses: muscle-growth / muscular-dystrophy research (preclinical/gene-therapy context). The evidence base is largely preclinical (animal/in-vitro); published randomised human clinical trials are lacking or absent. Note: most uses are not approved indications.

How does Follistatin-344 work?

Mechanism: Glycoprotein that binds and neutralises myostatin (and other TGF-beta family members), removing the brake on muscle growth in preclinical models.

Is Follistatin-344 safe?

Reported considerations: no human safety data for injected peptide, theoretical: off-target TGF-beta effects. The evidence base is largely preclinical (animal/in-vitro); published randomised human clinical trials are lacking or absent. Preclinical/gene-therapy research target. Injected-peptide use is unvalidated. Not approved. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of Follistatin-344?

Commonly cited ranges (educational reference, not a recommendation): low research-defined, typical no established safe human dose, high unknown. Administration: subcutaneous/intramuscular (anecdotal, unvalidated). Half-life: short for the protein; gene-therapy approaches differ.

Is Follistatin-344 legal in Australia?

Australian status: Not ARTG-registered; research. Preclinical/gene-therapy research target. Injected-peptide use is unvalidated. Not approved. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store Follistatin-344?

Reconstitution/storage reference: research-defined; storage: frozen aliquots.

What is Follistatin-344 commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): experimental anabolic protocols (anecdotal, high-uncertainty). Stacking increases interaction/safety uncertainty.
