- Low
- Tolerance assessment, elderly populations, maintenance phases
- 12.5mg daily
- +35–50%
- 1.2–1.8kg
- Low to Moderate
- Standard research dose, first-time users, recomposition focus
- 25mg daily
- +50–89%

- Moderate
- Experienced users, bulking phases, maximum anabolic stimulus
- 25mg twice daily
- +60–95%
- 1.5–2.4kg
- High
- Not recommended. Side effects outweigh marginal IGF-1 gains
- Professional Assessment
- Research-grade protocols converge on 25mg once daily as the optimal dose for muscle growth. Higher doses increase appetite and water retention without proportional IGF-1 or lean mass benefits
