- Circadian GHRH Receptor Sensitivity
- Low. Receptor density at nadir during waking hours
- High. Receptor density peaks in late evening
- Evening dosing produces 40–60% greater GH response per identical dose
- Somatostatin Tone (GH Inhibition)
- Elevated. Peaks during cortisol awakening response
- Suppressed. Lowest during slow-wave sleep
- Morning dosing fights active GH suppression; evening dosing works in permissive window
- Insulin Level (Anti-Lipolytic Signal)
- Elevated post-breakfast. Insulin blocks fat cell HSL activity
- Baseline/low during overnight fast. Maximises lipolytic response
- Peak GH during fasted state (evening) drives significantly more fat oxidation
- Cortisol Interference
- High. Cortisol awakening response suppresses GH secretion
- Low. Cortisol nadir occurs mid-sleep
- Evening injection avoids cortisol-mediated GH suppression
- Sleep Quality Impact
- Minimal GH elevation means no sleep architecture changes
- GH pulse during slow-wave sleep may deepen sleep quality
- Properly timed injection may improve sleep metrics in some users
- Clinical Trial Protocol
- Not studied. No published trials use morning dosing
- FDA trials used evening bedtime injection exclusively
- Evening dosing is the only evidence-based protocol
