Research Peptide | Lyophilized Powder | Batch Tested
For laboratory research use only. Not for human or animal consumption. Insulated shipping · Styrofoam box available.
Product Overview
IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid analog of insulin-like growth factor 1, engineered with an extra N-terminal extension and an arginine substitution. These changes dramatically reduce its binding to IGF-binding proteins, giving it far greater potency and a longer active life than native IGF-1.

Nominal sizes describe the product label; measured results are listed in each batch report. Published reports do not confirm the batch allocated to a future order.
Product & documentation questions
How do I read the size and pack quantity?
The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.
How do I find the matching COA?
Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.
Does a purity result mean every test passed?
No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.
Research Information
IGF-1 LR3 is studied for its potent activation of the IGF-1 receptor and downstream PI3K/Akt and MAPK signaling, driving cell proliferation, differentiation and anabolic pathways. Because it evades binding-protein sequestration, it is a favored tool for studying sustained IGF-1 signaling in cell-culture and animal models. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
