Ultimate Muscle Growth & Recovery Catalyst (Long-Acting IGF-1 Analog) IGF-1 LR3 is a highly potent, long-acting analog of Insulin-like Growth Factor-1 engineered for enhanced stability and extended active half-life. Designed to drive muscle protein synthesis, accelerate tissue repair, and support lean mass development in advanced metabolic research.
Key Highlights
-
Extended Half-Life & Superior Bioavailability: Features a 13-amino-acid N-terminal extension and a Substitution at position 3 (Glu to Arg), preventing binding to IGF binding proteins (IGFBPs) and extending active duration up to 20–30 hours.
-
Accelerated Muscle Protein Synthesis: Significantly stimulates cell proliferation, satellite cell activation, and hyperplastic muscle growth.
-
Rapid Recovery & Tissue Regeneration: Promotes cellular repair in skeletal muscle, tendons, ligaments, and connective tissue following heavy resistance or strain.
-
Nutrient Partitioning & Lean Mass Optimization: Enhances amino acid and glucose uptake in muscle tissues while discouraging fat storage.
Mechanism of Action
IGF-1 LR3 operates through precise cellular pathways:
-
IGF-1 Receptor Activation: Binds to the IGF-1 receptor to trigger the Akt/mTOR signaling cascade, driving cell growth and protein synthesis.
-
IGFBP Resistance: Structural modification prevents IGFBPs from deactivating the molecule, allowing full bioactivity over prolonged periods.
-
Hyperplasia & Hypertrophy: Stimulates both the expansion of existing muscle cells (hypertrophy) and the formation of new muscle fibers (hyperplasia).
Keep lyophilized peptides sealed in their original vial, protected from light and humidity, and store at -4°F or colder for optimal long-term stability in research settings; short-term refrigeration at around 39°F suffices for immediate use within weeks, though freezer storage maximizes integrity across extended research timelines.
