About:
A myostatin-binding protein variant studied in gene therapy research for muscular dystrophy.
What does this peptide do?
Human evidence is limited or indirect. Research focuses on myostatin binding and muscular dystrophy.

Myostatin binding
Binds myostatin, a regulator of muscle growth.

Muscular dystrophy research
Studied in gene therapy research for muscular dystrophy.
Evidence grade
CHighest evidence grade among the graded claims: C. Grades reflect study strength, not benefit.
What are the benefits and side effects of this peptide
What research says it may help with
- Follistatin's myostatin-binding role is well established in the literature, and follistatin gene therapy appears in reviews of muscular dystrophy and sarcopenia research.
- No trial of injectable follistatin protein in healthy people was found in the literature searched.
Who should avoid it
- People who are pregnant or breastfeeding
- Children and adolescents
- People with active or prior cancer, since myostatin pathway manipulation is not characterised for safety
- Known hypersensitivity to peptide preparations
See the safety section. Absence of a flag is not evidence of safety.
A grade reflects evidence strength, not a recommendation to use this compound; a strong grade can attach to a harmful effect.

How to store this peptide
Typically sold as a lyophilized powder. Reconstituted solutions are perishable, need refrigeration, and require clean handling to avoid contamination.
Lyophilized storage
Store at −20 °C, protected from light.
Reconstituted storage
Keep at 2–8 °C and use within a short period. For longer storage, aliquot and freeze at −20 °C.
Storage Handling
Avoid repeated freeze–thaw cycles. Let the vial reach room temperature before opening.
