IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) by Peptide Hubs is a high-performance peptide known for its powerful anabolic, fat-burning, and recovery-enhancing effects. This 1 mg lyophilized vial offers a research-grade version of one of the most effective growth peptides on the market, now available with U.S.-friendly shipping and uncompromising quality.
IGF-1 LR3 is a synthetic analog of natural IGF-1, engineered for enhanced stability and a prolonged half-life (~20–30 hours). It binds to IGF receptors and insulin receptors to promote muscle cell proliferation, protein synthesis, and tissue regeneration. Unlike natural IGF-1, the LR3 version resists binding proteins, allowing it to stay active longer and more effectively.
Common dosing ranges between 20–50 mcg daily, often injected subcutaneously post-workout. IGF-1 LR3 can also be administered intramuscularly into targeted muscle groups for localized growth stimulation. Protocols typically last 4 to 6 weeks, followed by off-cycles to maintain receptor sensitivity.
Once reconstituted with bacteriostatic water, store refrigerated and use within 20–30 days. Do not expose to high heat or direct light.
Stacking IGF-1 LR3 can enhance its performance-enhancing and recovery-based effects. Consider combining it with:
IGF-1 has been widely studied for its regenerative and anabolic effects. One clinical study demonstrated IGF-1's potent role in muscle hypertrophy, glucose regulation, and tissue repair in both young and aging subjects. The LR3 variant extends these benefits further through increased bioavailability.
Peptide Hubs provides pharmaceutical-grade peptides backed by full lab reports and GMP-level manufacturing. Each vial of this growth-boosting peptide is independently tested to verify purity and potency—ideal for athletic recovery, body recomposition, and scientific study.
Keep lyophilized powder refrigerated (2–8°C). After reconstitution with 1–2 mL of bacteriostatic water, store refrigerated and use within 30 days. Avoid repeated freeze-thaw cycles and heat exposure.
IGF-1 LR3 is a standout peptide in the realm of growth enhancement and performance recovery. Whether you're an advanced researcher or athlete pursuing greater results in lean muscle gain, fat reduction, or post-injury repair, Peptide Hubs IGF-1 LR3 1 mg offers a trusted, high-quality choice for serious outcomes.
