- The table below compares three common approaches researchers use when they stack CJC-1295 and MK-677, highlighting differences in dosing frequency, IGF-1 response, and practical implementation.
- Conservative Stack
- 1mg twice weekly (Mon/Thu)
- 12.5mg daily (nocturnal)
- +40–60% from baseline by week 4
- Lowest side effect incidence; ideal for first-time researchers; slower IGF-1 climb allows monitoring
- Best for protocols prioritizing safety data and compliance over maximal GH output
- Standard Stack
- 2mg twice weekly (Mon/Thu)
- 25mg daily (nocturnal)
- +80–120% from baseline by week 4
- Most commonly cited in published research; balances efficacy with tolerability; water retention moderate
- Gold standard for body composition and metabolic research—proven dose range with extensive safety data
- High-Output Stack
- 2mg three times weekly (Mon/Wed/Fri)
- 25mg daily (split AM/PM dosing)
- +120–180% from baseline by week 4
- Higher incidence of joint stiffness, water retention, and glucose elevation; requires weekly monitoring
- Reserved for advanced research models with established GH tolerance; not appropriate for initial protocols
