Peptides

IGF-1 LR3 1 mg

IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a synthetic, long-acting analogue of human IGF-1 with significantly reduced affinity for IGF-binding proteins. This modification enhances its bioavailability, stability, and research activity, making it one of the most widely used growth factors in cellular growth, muscle regeneration, and metabolic signaling studies. IGF-1 LR3 is valuable in research environments investigating anabolism, cell differentiation, protein synthesis, muscle hypertrophy, and tissue repair. Its extended half-life allows researchers to model prolonged IGF-1 signaling in controlled conditions.

Key Benefits

(Observed in controlled preclinical and laboratory research settings)

Enhanced Cell Growth: Supports research exploring myoblast proliferation, protein synthesis, and cellular regeneration.
Extended Half-Life: Modified to resist binding-protein inactivation, enabling longer activity than native IGF-1.
Muscle Hypertrophy Research: Commonly used to study muscle growth, repair after damage, and anabolic signaling pathways.
Metabolic Insight: Allows evaluation of glucose uptake, insulin sensitivity, and metabolic adaptation.
Tissue Repair Models: Studied for roles in ligament, tendon, and soft-tissue healing processes.
Synergistic Applications: Frequently combined with MGF or PEG-MGF for dual-phase regeneration studies.

Potential Side Effects

(Typically mild and dose-dependent in research models)

Temporary redness or irritation at administration sites
Mild fatigue
Occasional headache
Rare short-term hypoglycemia in sensitive metabolic models
Light muscular fullness or tightness in regenerative studies

Side effects vary depending on dosage, biological model, and experimental conditions.

Storage & Stability

Store lyophilized IGF-1 LR3 at 2–8°C for short-term use.
For long-term storage, maintain at –20°C, protected from light and moisture.
After reconstitution, keep at 2–8°C and use within the recommended stability window.
