- 200mcg nightly
- 8–12% from baseline
- Minimal. Not statistically significant in most trials
- Very low. Occasional injection site redness
- Sub-therapeutic for most adults; better suited as maintenance after higher-dose induction
- 300mcg nightly
- 12–18% from baseline
- Modest lean mass gain (+1.5–2 kg); slight fat reduction (−1–1.5 kg)
- Low. Transient flushing in 10–15% of users
- Effective middle-ground for moderate anti-aging goals; balances efficacy and tolerability
- 500mcg nightly
- 20–30% from baseline
- Significant lean mass gain (+2.5–3.5 kg); notable fat reduction (−2–3 kg)
- Moderate. Flushing, mild water retention, occasional joint stiffness in 20–25%
- Standard research dose; maximizes GH pulse amplitude while staying below receptor saturation threshold
- 750mcg+ nightly
- 25–35% from baseline (plateaus above 500mcg)
- Marginal additional benefit beyond 500mcg protocols
- Elevated. Water retention, carpal tunnel symptoms, hyperglycemia risk increases
- Not recommended. Side effects increase without proportional GH response; receptor saturation limits gains
- This table reflects published trial data and observed dose-response relationships. Individual variation in pituitary reserve and GHRH receptor density means some adults respond robustly at 300mcg while others require 500mcg for measurable IGF-1elevation.
