IGF-1 LR3 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) IGF-1 LR3 should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store IGF-1 LR3?
Proper storage is critical for maintaining IGF-1 LR3's potency and safety. As a Growth factor analog, IGF-1 receptor agonist, IGF-1 LR3 is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized IGF-1 LR3?
Unreconstituted (freeze-dried) IGF-1 LR3: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted IGF-1 LR3?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted IGF-1 LR3. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if IGF-1 LR3 Has Gone Bad?
Reconstituted IGF-1 LR3 should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With IGF-1 LR3?
Lyophilized IGF-1 LR3 can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted IGF-1 LR3 is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on IGF-1 LR3 Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.

Frequently Asked Questions
What is IGF-1 LR3?
IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arginine 3) is a Growth factor analog, IGF-1 receptor agonist. Synthetic analog of endogenous IGF-1 with arginine extension and leucine substitution increasing half-life 20-30x over native IGF-1. It is researched for rapid muscle growth, accelerated recovery, bone density increase, tendon healing, neurological protection, localized anabolic effect at injection site.
What is the recommended IGF-1 LR3 dosage?
Common dosages: 20-100 mcg daily; conservative protocols use 20-40 mcg administered once daily, typically post-workout via subcutaneous injection (intramuscular for localized effect). Cycle length: 4-8 weeks maximum to prevent receptor desensitization and insulin resistance. Half-life: 20-30 hours (vs. ~15 minutes for native IGF-1). Use our peptide calculator for exact reconstitution math.
What are the side effects of IGF-1 LR3?
Hypoglycemia is the most critical risk (shakiness, sweating, confusion, potential loss of consciousness). Insulin resistance with prolonged use. Fluid retention, headaches, joint stiffness, carpal tunnel syndrome. Theoretical cancer risk through mitogenic effects at supraphysiological doses. Acromegalic changes possible with chronic abuse.
Is IGF-1 LR3 safe?
IGF-1 LR3 has shown a preliminary safety profile in research. Not FDA-approved. WADA prohibited at all times with no Therapeutic Use Exemption pathway. Classified as research reagent. All research should follow appropriate safety protocols.
