Dosage & Usage Guidelines
This peptide is widely used in the bodybuilding community to stimulate lean muscle gains and improve post-training recovery. Its extended half-life (~20–30 hours) allows for once-daily dosing. A standard protocol involves subcutaneous injections of 20–100 mcg per day, ideally post-workout or in targeted muscle groups for localized growth stimulation.
Stacking and Integration
IGF-1 LR3 is often stacked with growth hormone or testosterone-based compounds to enhance results. For example, combining it with Dragontropin or Testosterone Enanthate may support greater anabolic synergy and recovery.
Why Choose Dragon Pharma IGF-1 LR3?
Every batch is third-party tested to verify identity and potency. Backed by quality manufacturing, this peptide supports professionals aiming to push past plateaus and achieve advanced results. It is part of the wider Dragon Pharma products lineup, trusted globally for high-performance compounds and research-grade peptides.
Example IGF-1 LR3 Cycle
- Cycle Duration: 4–6 weeks
- Dosage: 50–100 mcg/day, 5 days on / 2 days off
- Stack Suggestions: Combine with HGH or testosterone derivatives for synergistic results
Adverse Effects
Possible side effects include joint stiffness, water retention, or mild hypoglycemia. Monitoring blood sugar levels and following a clean, structured dosing plan can help mitigate unwanted effects.
Post-Cycle Therapy (PCT)
Although IGF-1 LR3 is non-suppressive to testosterone, it's often followed by a light PCT—especially when used alongside anabolic steroids. Agents like Clomid or Nolvadex can help maintain hormonal balance and performance post-cycle.

Storage
Store the lyophilized powder at controlled room temperature (15–25°C) in a dry, dark place, away from direct light and moisture. The unopened vial should be kept in its original packaging to maintain stability.
After reconstitution, store the solution at 2–8°C and use within 14 days. Do not freeze. Discard any unused portion after the recommended storage period. Before use, inspect the solution and avoid use if it appears cloudy, discolored, or contains particulate matter, or if the vial or seal is compromised.
Keep out of reach of children. Follow proper handling and sterile injection practices during research use.
Proper storage conditions help maintain product stability and consistent performance across the product's shelf life.
Frequently Asked Questions
What is the difference between IGF-1 LR3 and regular IGF-1?
IGF-1 LR3 has a modified structure for a longer half-life (~20–30 hours), allowing for prolonged biological activity and improved effectiveness compared to regular IGF-1.
Can IGF-1 LR3 be used for fat loss?
Yes, IGF-1 LR3 supports fat loss indirectly by enhancing lean muscle mass and increasing protein synthesis, which boosts overall metabolic rate.
Do I need post-cycle therapy after using IGF-1 LR3?
While IGF-1 LR3 doesn't suppress testosterone, many users implement light PCT if used alongside anabolic steroids to restore full hormonal balance.
