IGF-1 LR3 Peptide
IGF-1 LR3 (Long R3 IGF-1) is a modified form of insulin-like growth factor-1 (IGF-1) studied in laboratory research involving cell growth, signaling, metabolism, and tissue biology. The “LR3” modification alters the peptide’s interaction with IGF-binding proteins compared with native IGF-1.

IGF-1 LR3 1mg – Research Peptide
For Research Use Only – Not for Human Consumption
IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic peptide analog of human IGF-1. It has been modified to extend its half-life in vitro, allowing for enhanced stability and prolonged activity during laboratory testing. The substitution of arginine at position 3 and removal of the first three amino acids in the native IGF-1 sequence make LR3 more resistant to binding proteins, thereby increasing its bioavailability in research environments.
Researchers value IGF-1 LR3 for its role in studying cellular growth, differentiation, survival pathways, and metabolic functions. It has been widely used in experimental models to explore muscle cell proliferation, neuroprotection, and regenerative mechanisms.

FAQ
What is IGF-1 LR3?
IGF-1 LR3 is a modified form of insulin-like growth factor-1 that has been developed primarily for research into IGF signaling and cellular processes.
What does LR3 mean?
“LR3” refers to a structural modification of IGF-1 that changes its interaction with IGF-binding proteins compared with native IGF-1.
What is IGF-1 LR3 used for?
It is used in laboratory research investigating IGF-related signaling, cellular growth, differentiation, and metabolic pathways.
Is IGF-1 LR3 FDA approved?
IGF-1 LR3 should not be presented as an FDA-approved medication. It is an experimental research compound.
Is IGF-1 LR3 safe?
Human safety data are limited, and the risks of using experimental IGF-1 LR3 products have not been adequately established.
Is IGF-1 LR3 the same as IGF-1?
No. IGF-1 LR3 is a modified form of IGF-1 with structural changes that affect its biological properties.
Is IGF-1 LR3 used for muscle growth?
IGF-1 signaling is involved in growth and cellular processes, but IGF-1 LR3 should not be marketed as an approved muscle-building or performance-enhancing treatment.
How can I verify IGF-1 LR3 quality?
Use a batch-specific COA to document the product’s identity, purity, molecular weight, and analytical testing.
