- The following table compares three evidence-based IGF-1 elevation research peptide stacks based on administration complexity, expected IGF-1 increase, and receptor cycling strategy.
- Foundation Stack
- MK-677 25mg oral + CJC-1295 DAC 2mg weekly
- Daily oral + weekly injection
- 60–90% above baseline
- MK-677 cycled 12 weeks on / 4 weeks off; DAC provides continuous GHRH tone
- Best for simplified protocols prioritizing compliance; sustained elevation with minimal injection frequency
- Pulsatile Amplification Stack
- GHRP-2 200mcg + Modified GRF 1-29 100mcg
- 3× daily (morning, post-training, pre-sleep)
- 100–150% above baseline during active periods
- Mimics natural GH pulses; minimal feedback suppression
- Highest peak IGF-1 levels; requires strict timing discipline; preferred for short-duration intensive protocols (8–12 weeks)
- Hybrid Rotation Stack
- MK-677 25mg daily + Ipamorelin 200mcg + CJC-1295 DAC 2mg (alternating weeks)
- Daily oral + 3× weekly injection
- 80–120% sustained elevation
- Rotates receptor targets weekly; prevents single-pathway saturation
- Optimal for long-duration research (16+ weeks); balances efficacy with receptor sensitivity preservation
