/FOLLISTATIN_344_1MG
Peptide

Follistatin 344

Myostatin Inhibitor Peptide

/HALF_LIFE
Several hours (exact data varies)
/DELIVERY
Subcutaneous or intramuscular injection

/WHAT_IT_IS

Follistatin 344 is a protein-based peptide known for its ability to inhibit myostatin, a negative regulator of muscle growth. By suppressing myostatin, it can promote hypertrophy and increased muscle mass.

/USAGE

Used in research related to muscle-wasting conditions, muscle regeneration, and performance enhancement.

/MECHANISM_OF_ACTION

Binds to and inhibits myostatin, thus allowing muscle tissue to grow beyond normal physiological limits.

Reported Benefits

  • +Increased muscle growth
  • +Reduced muscle degradation
  • +Potential support in sarcopenia or cachexia research

Reported Side Effects

  • Potential muscle stiffness
  • Unverified long-term safety
  • Possible organ enlargement if misused

/STACKED_WITH

IGF-1 LR3TB-500BPC-157

/RESEARCH_NOTES

May be particularly relevant in regenerative medicine and performance research, but lacks long-term human trial data.
