- Threshold Protocol
- 100mcg
- Morning fasted state
- 4–8 weeks
- 18–24%
- 8–12% above baseline
- Minimal effective dose for measurable anabolic signaling. Suitable for initial response assessment. Lower risk of activin cross-reactivity.
- Mid-Range Protocol
- 200mcg
- 30–60 min post-training
- 8–12 weeks
- 32–41%
- 15–21% above baseline
- Most common research dose. Balances myostatin inhibition with manageable side effect profile. Requires consistent training stimulus for maximal effect.
- High-Dose Protocol
- 300mcg
- Immediately post-training
- 43–47%
- 22–27% above baseline
- Maximal anabolic response in published models. Dose escalation beyond this range does not increase hypertrophy proportionally. Monitor for activin-related suppression of FSH.
- Split-Dose Protocol
- 150mcg twice daily (300mcg total)
- Morning + post-training
- 45–49%
- 20–26% above baseline
- Maintains more stable plasma levels than single daily dose. Requires strict adherence. Useful when targeting sustained myostatin suppression across 24-hour cycle.
