Sermorelin Before Bed Nighttime Dosing: Protocol Comparison
Alignment with endogenous GH pulse Poor. Daytime somatostatin tone high, endogenous GHRH minimal Moderate. Exercise-induced GH pulse present but smaller than nocturnal Excellent. Synchronises with nocturnal GHRH surge and somatostatin nadir Nighttime dosing yi

- Alignment with endogenous GH pulse
- Poor. Daytime somatostatin tone high, endogenous GHRH minimal
- Moderate. Exercise-induced GH pulse present but smaller than nocturnal
- Excellent. Synchronises with nocturnal GHRH surge and somatostatin nadir
- Nighttime dosing yields 2–4× greater GH response per published pharmacokinetic data
- Fasting state requirement
- Difficult. Conflicts with breakfast, post-meal insulin elevation likely
- Moderate. Requires 3+ hour gap from lunch, possible pre-workout fasting
- Easy. Natural overnight fast ensures low insulin/glucose baseline
- Nighttime administration naturally occurs in fasted state, removing compliance barrier
- Sleep-dependent amplification
- None. Sleep occurs 12+ hours later
- None. Sleep occurs 5–7 hours later
- Maximum. Sermorelin peak coincides with slow-wave sleep GH pulse
- Sleep is the largest physiological GH stimulus; sermorelin amplifies it only if timed correctly
- Practical adherence
- Low. Requires early wake-up, fasting through morning
- Moderate. Conflicts with gym schedule variability
- High. Integrates into existing bedtime routine
- Consistent timing drives consistent results; nighttime dosing has lowest protocol drift
