- Peptide + coffee simultaneously
- Cortisol elevated 30–50% within 15 min
- Reduced 20–40% due to gastric pH shift and accelerated transit
- Suppressed. Cortisol blocks GH secretion
- Morning protocols where convenience is prioritized over efficacy
- Least effective. Avoid unless individual tolerance is confirmed
- Coffee first, peptide 30 min later
- Cortisol remains elevated 60+ min
- Normal absorption kinetics, but receptor sensitivity reduced
- Blunted. Cortisol still elevated during peptide peak action
- Habitual coffee drinkers with partial cortisol tolerance
- Suboptimal. Better than simultaneous but not ideal
- Peptide first, coffee 30–60 min later
- Peptide works in low-cortisol window, caffeine spike occurs after peak peptide action
- Optimal. No gastric interference, normal transit time
- Preserved. Peptide acts before cortisol elevation
- Standard research protocol for GH secretagogues and cognitive peptides
- Optimal. Preserves efficacy while allowing caffeine use
- Peptide first, no coffee for 90+ min
- No cortisol interference at any phase
- Optimal
- Fully preserved
- Maximum efficacy protocols, fasted morning administration
- Best for maximal response. Inconvenient for daily routines
