Follistatin 344 vs GHRP-6
An educational, source-based comparison of Follistatin 344 and GHRP-6 — 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 hexapeptide ghrelin receptor (GHS-R1a) agonist that stimulates pituitary GH release and increases appetite via central ghrelin pathways. One of the earliest GH-releasing peptides studied.
- Endogenous GH pulse stimulation
- Appetite stimulation in cachexia models
- Cardioprotective signaling (preclinical)
- • Increases appetite and may elevate cortisol/prolactin more than newer secretagogues.
- • Not FDA-approved; banned by WADA.
