IGF-1 LR3 1mg Peptides
Set a higher standard for your study from the first vial.
The Primavora IGF-1 LR3 lyophilized peptide vial is produced for researchers who require precision, consistency, and clear documentation. This 1mg presentation of IGF-1 LR3 arrives as a stable freeze-dried solid in a Peptide Lyophilized Vial format, engineered for dependable handling and reproducible results across method development and exploratory work.
- Each vial contains 1mg of IGF-1 LR3, a long-acting analog of insulin-like growth factor 1 commonly examined for extended receptor interaction, downstream signaling, and growth-factor pathway investigations in controlled in vitro and ex vivo models.
Developed for laboratory use, this non-edible research material is prepared to reconstitute cleanly with suitable sterile diluents under aseptic technique, supporting accurate aliquoting and method calibration. The lyophilized format helps preserve integrity through storage and transport; for best stability, store cold, protect from light, and minimize repeated freeze-thaw by aliquoting after reconstitution as appropriate to your protocol.
Primavora emphasizes process control at every step. Synthesis and filling are performed in the United States under rigorous, peptide-focused quality systems. Each lot is verified by HPLC for identity and purity, with orthogonal mass spectrometry confirmation and screening for bioburden and endotoxins. Tamper-evident packaging, lot-level traceability, and a detailed Certificate of Analysis support transparent review and method documentation. Our teams prioritize material cleanliness, careful handling, and consistent specifications to help reduce variables in your workflow.
Whether you are building dose–response curves, evaluating receptor kinetics, or conducting comparative pathway studies, this IGF-1 LR3 vial is designed to integrate cleanly into standard laboratory practices. The focus is reliability: consistent composition, clear labeling, and data-backed release criteria that allow you to concentrate on your experiment—not your inputs.
Quality and safety: USA-made, HPLC and MS tested, sterile-packaged, lot-traceable, and supported by a comprehensive COA. Primavora delivers research-grade peptides with uncompromising attention to purity and documentation so your lab can proceed with confidence.

Frequently Asked Questions
What is IGF-1 LR3?
IGF-1 LR3 is a modified long-acting analog of insulin-like growth factor 1. It is engineered for altered binding behavior and extended activity compared with native IGF-1, which is why it is treated as a distinct research molecule. On a site like this, it should be described as a research peptide tied to growth and metabolic signaling studies.
What is IGF-1 LR3 typically studied for?
Researchers usually investigate IGF-1 LR3 for cell proliferation, anabolic signaling, glucose uptake, and tissue-growth pathways. Because it acts downstream of growth-related signaling, it should be discussed carefully and scientifically, without implying that it is an approved product for muscle gain or performance use.
What are growth factors?
Growth factors are a class of signaling proteins and peptides that regulate cell proliferation, differentiation, and survival. Well-studied examples include insulin-like growth factor 1 (IGF-1), fibroblast growth factors (FGFs), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and nerve growth factor (NGF).
In research, growth factors are essential tools for cell culture, regenerative biology, developmental studies, and cancer research. They are typically used at low concentrations to stimulate specific cellular responses in vitro. All growth factor products from Prima Vora are intended for laboratory research use only.
What is the role of IGF-1 in research?
Insulin-like growth factor 1 (IGF-1) is a 70-amino-acid peptide with significant structural similarity to insulin. It is one of the most-studied growth factors in research and is a central player in studies of cell proliferation, differentiation, metabolism, and tissue growth. IGF-1 acts through its own receptor (IGF-1R), which shares downstream signaling components with the insulin receptor.
In the laboratory, IGF-1 is used as a reference ligand in receptor-binding studies, as a supplement in cell culture media for certain cell lines, and as a model peptide in studies of the PI3K/AKT/mTOR signaling pathway. IGF-1 products from Prima Vora are supplied for these kinds of research applications only.
How do growth factors differ from peptide hormones?
Peptide hormones — such as insulin, glucagon, and growth hormone — are typically produced by specialized endocrine glands and act on distant target tissues as part of systemic regulation. Growth factors are usually produced by a wider variety of cell types and tend to act in a more local manner, through autocrine or paracrine signaling on nearby cells.
Another difference lies in their biological roles: peptide hormones are generally studied in the context of metabolic and endocrine regulation, while growth factors are more commonly studied in the context of development, tissue repair, and proliferation. In practice, the categories overlap, especially for molecules like IGF-1 that behave in both ways.
