Follistatin 344 vs Ipamorelin
An educational, source-based comparison of Follistatin 344 and Ipamorelin — how each peptide works, what it's researched for, and what to know before going deeper.
Myostatin-binding protein fragment researched for muscle growth.
A naturally occurring glycoprotein that binds and neutralizes myostatin and activin, releasing the natural brake on skeletal muscle growth in preclinical models.
- Muscular dystrophy models
- Skeletal muscle hypertrophy
- Age-related sarcopenia (preclinical)
- • Off-target effects on activin signaling (reproductive, cardiac) are a concern.
- • Not FDA-approved; banned by WADA.
A selective ghrelin/GHS-R1a receptor agonist that stimulates GH release with minimal effect on cortisol, prolactin, or appetite — distinguishing it from older secretagogues like GHRP-6.
- Endogenous GH release without cortisol elevation
- Sleep quality and recovery markers
- Lean tissue retention in catabolic states
- • Generally well tolerated in research; long-term human safety data are limited.
- • Not FDA-approved.
- • Use in sport is prohibited (WADA).
