What is IGF-1 LR3?
IGF-1 LR3 is a modified version of human insulin-like growth factor-1. The “LR3” version is designed with structural changes that reduce binding to IGF binding proteins, which is why it is commonly discussed as having longer activity and greater systemic bioavailability than native IGF-1.
In research discussions, IGF-1 LR3 is commonly associated with anabolic signalling, protein synthesis, metabolic function, cellular growth pathways and glucose-related effects.
IGF-1 LR3 Reconstitution Example
The example below is based on a common 1mg IGF-1 LR3 vial mixed with 3.0mL bacteriostatic water.
Reconstitution Maths
1mg ÷ 3.0mL = 0.333mg/mL
0.333mg/mL = 333mcg/mL
1 unit on a U-100 syringe = 0.01mL
333mcg/mL × 0.01mL = approximately 3.33mcg per unit

Standard Gradual Research Example
This example uses a 1mg vial reconstituted with 3.0mL bacteriostatic water, giving a concentration of approximately 333mcg/mL.
Frequency and Timing Notes
IGF-1 LR3 is commonly discussed as a once-daily subcutaneous compound in research-style examples. Timing is often discussed around morning or post-workout use with food intake because of its insulin-like effects on blood glucose.
The source protocol strongly focuses on conservative amounts, with 20-50mcg daily shown as the main example range. It also notes that doses above 50-60mcg per day may carry greater safety concerns.
Reconstitution Steps
- Confirm the vial size before calculating concentration.
- Draw 3.0mL bacteriostatic water using sterile technique.
- Inject the bacteriostatic water slowly down the inside wall of the vial.
- Avoid blasting the powder directly and do not shake.
- Gently swirl or roll the vial until the powder fully dissolves into a clear solution.
- Label the vial with the reconstitution date and concentration.
- Store the reconstituted vial in the refrigerator at 2-8°C, protected from light.
- Use within around 30 days after reconstitution.
Supplies Needed
IGF-1 LR3 Vials
- 8-week example: approximately 3 × 1mg vials.
- 12-week example: approximately 4 × 1mg vials.
- 16-week example: approximately 6 × 1mg vials.
Insulin Syringes
- Daily example: 7 syringes per week.
- 8 weeks: approximately 56 syringes.
- 12 weeks: approximately 84 syringes.
- 16 weeks: approximately 112 syringes.
Bacteriostatic Water
- Per 1mg vial: 3.0mL bacteriostatic water.
- 8-week example: 3 vials × 3.0mL = 9mL total, so 1 × 10mL bottle is usually enough.
- 12-week example: 4 vials × 3.0mL = 12mL total, so 2 × 10mL bottles may be needed.
- 16-week example: 6 vials × 3.0mL = 18mL total, so 2 × 10mL bottles may be needed.
Alcohol Swabs & Safety Items
- Per administration: one swab for the vial stopper and one for the injection site.
- 8 weeks: around 112 swabs, so 2 × 100-count boxes may be needed.
- 12 weeks: around 168 swabs, so 2 × 100-count boxes may be needed.
- 16 weeks: around 224 swabs, so 3 × 100-count boxes may be needed.
- Sharps container: for safe disposal of used needles and syringes.
- Fast-acting carbohydrate source: glucose tablets or juice are commonly discussed because of possible hypoglycemia symptoms.
Protocol Overview
- Goal discussed in research: anabolic signalling, metabolic function and extended IGF-1 activity.
- Schedule example: daily subcutaneous administration.
- Common amount discussed: 20-50mcg daily with gradual titration.
- Example reconstitution: 3.0mL bacteriostatic water per 1mg vial.
- Concentration: approximately 333mcg/mL.
- Cycle length: 8 weeks is commonly discussed.
- Off-period: 4-8 weeks off is commonly discussed to reduce diminished response.
- Timing: often discussed with or shortly after food intake.
Example Dosing Protocol
- Weeks 1-2: 20mcg daily to assess tolerance.
- Weeks 3-4: 40mcg daily if the first phase is well tolerated.
- Weeks 5-8: 50mcg daily as the conservative upper end in the source protocol.
- Practical note: at this dilution, small amounts may be easier to read with 30-unit or 50-unit insulin syringes.
How IGF-1 LR3 Works
IGF-1 LR3 is a synthetic analog of human IGF-1. It includes structural changes that reduce binding to IGF binding proteins, which can extend its circulation time compared with native IGF-1.
The compound is discussed for anabolic and metabolic activity through IGF-1 receptor pathways. Because IGF-1 has insulin-like properties, glucose management is one of the most important safety considerations.
Potential Benefits Discussed in Research
- Anabolic signalling research
- Protein synthesis discussions
- Extended IGF-1 bioavailability
- Metabolic pathway research
- Cellular growth signalling
- IGF-1 receptor activity discussions
Reported Side Effects and Limitations
- Hypoglycemia risk, including shakiness, sweating, dizziness or confusion
- Injection-site redness or discomfort
- Potential glucose instability
- Diminished response with prolonged continuous use
- Greater safety concerns at higher amounts
- No FDA approval for human therapeutic use
Storage Instructions
- Lyophilised powder: store frozen at around -20°C for longer-term storage, protected from heat, moisture and light.
- After reconstitution: refrigerate at 2-8°C immediately.
- Use window: commonly discussed as within 30 days after reconstitution.
- Extended storage: sterile aliquots may be frozen for longer storage, but thawed material should not be refrozen.
- Discard: if the solution becomes cloudy or contains particles.
- Avoid: heat, sunlight, contamination and repeated freeze-thaw cycles.
Injection Technique Notes
This section is general educational information only. It is not personal injection instruction.
- Use a new sterile insulin syringe for each administration.
- Clean the vial stopper and skin with alcohol and allow both to dry.
- Common subcutaneous sites discussed include abdomen, outer thighs, upper arms and upper outer buttocks.
- Rotate injection sites systematically.
- Pinch a skinfold and insert into subcutaneous tissue at an appropriate angle.
- Do not aspirate for subcutaneous injections.
- Inject slowly over a few seconds.
- Withdraw at the same angle and apply gentle pressure.
- Do not rub the site vigorously.
- Dispose of used sharps safely in a sharps container.
Lifestyle Factors That May Matter
- Nutrition: regular meals and adequate protein are commonly discussed alongside IGF-1 signalling.
- Meal timing: food intake is commonly discussed to help manage glucose-related effects.
- Training: resistance training and recovery may support anabolic research goals.
- Sleep: quality sleep supports endogenous growth-factor and tissue repair processes.
- Hydration: consistent hydration may support metabolic function.
- Glucose monitoring: blood glucose checks may be relevant during titration, particularly if symptoms occur.
