Follistatin-344
Myostatin inhibitor.
Mechanism of Action
Blocks myostatin.
Key Benefits
- Extreme muscle growth potential
Common Uses
What to Expect
Onset
Strength and density improvements within 1–2 weeks of the short cycle
Duration
Short cycles of 10–14 days only; effects can persist after stopping as myostatin suppression lingers
What Users Report
- Noticeable increase in muscle hardness and density — muscles feel 'denser' and more solid
- Enhanced strength that can be felt within the first week of the cycle
- Very limited user experience data due to the experimental nature — this is on the frontier of peptide research
- Some report feeling 'stronger' and more powerful in their training within days
- Effects are subtle but measurable — don't expect overnight transformation
- This is considered an advanced-only peptide; not recommended for beginners
- Long-term safety profile is not well established — use with caution and medical supervision
Typical Timeline
Days 1–5: Myostatin suppression begins; subtle changes in muscle tone. Days 5–10: Strength improvements become noticeable; muscles feel harder. Days 10–14: Cycle complete; peak effects. Post-cycle: Effects can persist as myostatin levels take time to normalize. Important: Keep cycles short due to unknown long-term effects.
Side Effects
- Unknown long-term
Dosage Protocol
100–200 mcg subcutaneously daily. Cycles: 10–14 days; short to avoid overgrowth.
Always consult a physician before starting any peptide protocol.
