IGF-1 LR3 is a synthetic analog of insulin-like growth factor-1 (IGF-1), modified to extend its half-life and potency in stimulating cellular growth.
Commonly used in research for promoting muscle growth, recovery, and tissue repair by enhancing protein synthesis and nutrient uptake.
Binds to IGF-1 receptors in muscle and other tissues, promoting anabolic activity and inhibiting programmed cell death.
IGF-1 LR3 is a synthetic analog of insulin-like growth factor-1 (IGF-1), modified to extend its half-life and potency in stimulating cellular growth.
IGF LR3 has an approximate half-life of 20–30 hours. The half-life determines how often you need to inject to maintain steady blood levels — use the Peptides Calculator half-life calculator to plot your specific dosing schedule and see the decay curve.
IGF LR3 is typically delivered via subcutaneous or intramuscular injection. The Peptides Calculator app helps you reconstitute the vial with bacteriostatic water, calculate your exact dose in syringe units, and track each injection.
