- 30–60 min before sleep
- 16–22 ng/mL
- 4–6 hours
- Optimal. Syncs with natural nocturnal pulse
- Requires 3+ hour fast, consistent sleep schedule
- Gold standard for most users. Highest amplitude, longest duration, minimal interference
- Upon waking (fasted)
- 6–9 ng/mL
- 90–120 minutes
- Poor. Cortisol peak inhibits tissue response
- Must inject before food/coffee, awkward for morning routines
- Suboptimal but viable if sleep timing is inconsistent. Plan for 40–60% reduced efficacy
- Post-workout (60–90 min after training)
- 8–12 ng/mL
- 2–3 hours
- Moderate. Exercise primes pituitary but insulin blunts response
- Requires fasted training or precise carb timing
- Useful for shift workers or late trainers. Response variable depending on workout intensity
- Mid-afternoon (3–5 PM, fasted)
- 5–8 ng/mL
- 90 minutes
- Poor. Somatostatin tone elevated, no circadian support
- Difficult to maintain fasting window in social/work contexts
- Least effective window. No physiological rationale, cortisol still elevated, GH stores depleted
- This table reflects mean values from comparative GH secretagogue studies. Individual response varies based on age, body composition, sleep quality, and baseline GH status. The nocturnal protocol consistently outperforms alternatives across populations.
