Peptides

IGF-1 LR3 0.1 mg

IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is an extended-activity analogue of native IGF-1 engineered to reduce binding to IGF-binding proteins, significantly increasing its bioavailability, stability, and duration of action. This 0.1 mg research format is ideal for laboratories requiring smaller-dose studies, precision testing, or controlled incremental protocols. IGF-1 LR3 is widely used in research involving cell growth, muscle hypertrophy, protein synthesis, tissue regeneration, and metabolic signaling. Its long half-life and consistent biological activity make it a preferred tool for modelling prolonged IGF-1 pathway activation.

Key Benefits

(Observed in controlled preclinical and laboratory research models)

Cell Growth & Proliferation: Supports studies evaluating myoblast activity, cellular repair, and regenerative pathways.
Extended Biological Activity: Modified structure provides longer activity compared to native IGF-1.
Muscle Hypertrophy Models: Frequently used to explore muscle growth, recovery from micro-trauma, and anabolic signaling.
Metabolic Function Research: Useful for examining glucose uptake, insulin sensitivity, and muscle-energy utilization.
Tendon & Soft-Tissue Studies: Studied for its involvement in collagen formation, tendon repair, and connective-tissue healing.
Synergistic Research Applications: Often paired with MGF or PEG-MGF for comprehensive regeneration modeling.

Potential Side Effects

(Generally mild and dose-dependent in research environments)

Mild injection-site irritation
Temporary headache
Occasional fatigue
Rare transient hypoglycemia in metabolic models
Light muscle fullness or tightness depending on protocol

Side effects vary with dose, biological model, and experimental design.

Storage & Stability

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