IGF-1 LR3 is a modified analog of insulin-like growth factor-1 engineered for use in controlled laboratory environments. This synthetic variant features an extended amino acid sequence that differentiates it structurally from endogenous IGF-1 and makes it a defined tool for investigative research.
West Peptides provides IGF-1 LR3 in a high-purity, lyophilized format suitable for analytical studies and experimental protocols requiring sequence-specific peptide materials.
IGF-1 LR3 has been referenced in scientific literature examining peptide-receptor interactions and downstream signaling activity. In preclinical and laboratory models, researchers use defined IGF variants to better understand receptor binding dynamics, pathway modulation, and molecular response behavior under controlled conditions.
Because this peptide includes structural modifications relative to naturally occurring IGF-1, it is often selected in experimental designs where distinct receptor engagement characteristics are being evaluated.
This product is supplied as a white lyophilized powder to support stability and precise preparation. Lyophilization preserves structural integrity and allows researchers to reconstitute the peptide using appropriate sterile solvents within laboratory settings.
IGF-1 LR3 is commonly incorporated into research workflows where defined peptide fragments are used to investigate cellular signaling systems and controlled molecular response pathways.

What is IGF-1 LR3?
IGF-1 LR3 is a synthetic variant of insulin-like growth factor-1 that includes structural modifications and is referenced in research involving receptor signaling pathways.
Why do researchers use IGF-1 LR3 instead of native IGF-1?
Modified analogs are often selected in research to evaluate differences in receptor interaction and molecular behavior under controlled conditions.
This product is intended strictly for laboratory research and scientific investigation purposes only. IGF-1 LR3 is not approved for human or veterinary use. It is not intended for use as a drug, dietary supplement, cosmetic, or food product.

Our products are produced using a freeze-drying process (lyophilization), which helps maintain their integrity and stability during transit, typically for up to 3–4 months.
After the peptides are reconstituted (mixed with bacteriostatic water), they should be kept refrigerated to preserve their quality. Once in liquid form, they generally remain stable for up to 30 days when stored properly.
Lyophilization—also referred to as cryodesiccation—is a dehydration method where the material is first frozen and then exposed to low pressure. This allows moisture to transition directly from solid to vapor, leaving behind a dry, stable compound in the form of a light, crystalline powder. In this state, the product can be kept at room temperature until it is ready to be reconstituted.
Upon receiving your peptides, it is recommended to protect them from heat and light exposure. For short-term use (ranging from a few days to several weeks), refrigeration below 4°C (39°F) is suitable. Lyophilized products can also tolerate room temperature storage for a limited period if they will be used relatively soon.
For extended storage—spanning several months or longer—freezing is advised. Ideally, peptides should be kept at approximately -80°C (-112°F) to best maintain long-term stability
