- Before selecting a dosing strategy, understanding how different protocols perform across key variables. Dose range, injection frequency, nutrient timing, and expected outcomes. Provides context for matching protocol to research objectives. The table below compares three common IGF-1 LR3 dosing approaches used in fat loss research, highlighting critical differences in application and results.
- Low-Dose Preservation
- 20–40 mcg
- Once daily (morning fasted)
- Caloric deficit required
- Lean mass retention during restriction
- Indirect. Fat loss driven by deficit, not compound
- 6–8 weeks before plateau
- Best for research models prioritising muscle preservation during aggressive cuts; fat loss is secondary to anti-catabolic effect
- Mid-Range Partitioning
- 40–80 mcg
- Once daily or split (morning + post-training)
- Carbohydrate intake timed around training
- Active nutrient partitioning toward muscle
- Moderate fat loss with simultaneous lean mass maintenance
- 4–6 weeks before titration needed
- Most versatile protocol; effective in maintenance or mild deficit with resistance training stimulus; balances efficacy and receptor longevity
- High-Dose Recomposition
- 80–120 mcg
- Split dosing (morning + post-training mandatory)
- Caloric surplus or maintenance with high training volume
- Anabolic partitioning away from adipose storage
- Gradual fat loss despite neutral/positive energy balance
- 3–4 weeks before receptor desensitisation
- Advanced protocol for research exploring recomposition dynamics; requires precise nutrient timing and structured training; highest risk of diminishing returns if extended beyond 4 weeks
