- 200mcg once daily
- 1x daily
- Morning fasted or pre-bed
- Single daily pulse; mild amplitude
- Minimum effective research dose; used for initial tolerance assessment
- Suitable for conservative titration; unlikely to cause receptor saturation but requires 8–12 weeks to observe measurable shifts
- 200–300mcg twice daily
- 2x daily
- Morning fasted + pre-bed
- Dual-pulse mimicking natural rhythm
- Standard anti-aging research protocol; aligns with endogenous GH secretion
- Most common approach in published studies; dual dosing avoids receptor desensitization while maintaining stable serum IGF-1 elevation
- 300–500mcg twice daily
- Supraphysiological amplitude; increased IGF-1
- Performance-focused research; used in combination with other secretagogues
- Higher risk of receptor downregulation beyond 12 weeks; typically reserved for short-term intensive protocols or stacked approaches
- 100mcg three times daily
- 3x daily
- Morning, afternoon, pre-bed
- Multiple smaller pulses throughout the day
- Alternative strategy to prevent tachyphylaxis; maintains receptor sensitivity
- Logistically complex; requires fasted state for afternoon dose; used primarily when twice-daily dosing shows diminishing returns
- Researchers should note that 'more is better' does not apply to growth hormone secretagogues. Ipamorelin works by amplifying endogenous GH pulses. Not replacing them. Doses above 300mcg per administration do not proportionally increase GH output; they simply extend the duration of the pulse without adding amplitude. The 200–300mcg twice-daily protocol reflects the dose range used in most peer-reviewed studies and avoids receptor saturation that reduces responsiveness over time.
