Follistatin 344 vs Somatrogon (Ngenla)
An educational, source-based comparison of Follistatin 344 and Somatrogon (Ngenla) — 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.
Long-acting recombinant human growth hormone for pediatric GH deficiency — weekly dosing.
A long-acting recombinant fusion protein of human growth hormone with three copies of the C-terminal peptide (CTP) of hCG beta-subunit, extending half-life and enabling once-weekly subcutaneous dosing instead of daily.
- Pediatric growth hormone deficiency
- • FDA-approved June 2023.
- • Same class warnings as daily GH (intracranial hypertension, glucose effects, scoliosis progression).
- • Injection-site reactions common.
Follistatin 344 vs Somatrogon (Ngenla) — Key differences
- Class: Follistatin 344 is classified as Muscle · Myostatin Inhibition, while Somatrogon (Ngenla) is GH Analog · Endocrine.
- Primary research focus: Follistatin 344 — muscular dystrophy models; Somatrogon (Ngenla) — pediatric growth hormone deficiency.
- Tag: Muscle vs FDA-Approved · Endocrine.
