Description
IGF-1 LR3 is an 83-amino acid synthetic analog of native IGF-1 featuring an arginine substitution at position 3 and a 13-amino acid N-terminal extension. These modifications reduce its binding affinity to IGF-binding proteins by over 100-fold, extending its half-life to approximately 20–30 hours compared to 12–15 minutes for unmodified IGF-1. This results in sustained IGF-1R activation and potent anabolic signaling via PI3K/Akt and MAPK/ERK pathways. Research shows it promotes skeletal muscle hypertrophy and hyperplasia, satellite cell proliferation, enhanced glucose uptake independent of insulin, accelerated wound healing, collagen deposition, and neuroprotective effects. While offering significant benefits for muscle growth, tissue regeneration, and body composition research, potential side effects include hypoglycemia, water retention, injection-site reactions, and theoretical risks of visceromegaly or tumor promotion with prolonged high-dose use. Cyclical administration with glucose monitoring is typically recommended in research settings. This content is for research purposes only and is provided solely for reference.

Questions about IGF-1 LR3
What is the intended use of IGF-1 LR3?
Research reagents are intended solely for laboratory and in-vitro research. Suitability for a particular experiment must be assessed using the exact specification and available documentation. Accessories and consumables must be used according to their own specifications and documented intended use.
Can research reagents be used by or administered to people?
No. Research reagents are not for human use, diagnosis, treatment, prevention, clinical procedures or self-medication. A research-use label does not authorize use in people.
How can I verify the identity of IGF-1 LR3?
No CAS number is published on this page. Do not infer the material's identity from its name. Request identification details and documentation for the exact product from the supplier.
Is a certificate of analysis (COA) available for IGF-1 LR3?
No COA is currently published on this page in the selected language. Ask the supplier about documents for the exact batch before use; availability is not guaranteed. A COA does not establish safety for human use or medical approval.
Does a purity result or COA establish safety for human use?
No. A reported purity result describes the sample and test recorded in the document. It does not establish safety for human use, clinical suitability or medical approval. Review the method, batch identity and relevant specifications for your laboratory work.
How should IGF-1 LR3 be stored and handled?
The storage information published for this product is: Refrigerate at low temperature (2-8°C). Avoid freezing and exposure to light.. Confirm the batch-specific storage and handling instructions with the supplier before receipt and use.
Does an available shipping option mean the product can be imported?
No. A shipping quote at checkout is not import authorization. Before ordering, verify whether the exact product and quantity are admissible at the destination and what purchasing, import, documentation and use requirements apply.
What should I confirm before procurement?
Match the SKU, specification and batch or lot identifier to your research requirements. Request any required COA and safety documentation and confirm availability before ordering; documents are not guaranteed to be available. Also verify applicable requirements at the destination.
