Storage & Handling
- Product-Specific Storage
This product is supplied as a freeze-dried material. Keep the original container sealed and follow the storage condition shown on the product label or available documentation.
Follow the format-specific instruction shown above. Product-specific label or documentation requirements take priority over the general handling guidance below. - Keep the Original Container Sealed
Until the material is needed for laboratory work, keep it in its original sealed container. Protect it from moisture, unnecessary light exposure, and avoidable temperature fluctuations. - Inspect the Package on Receipt
Check the container, seal, and packaging for visible damage, condensation, or signs of a temperature excursion. Record any issue before placing the material into laboratory storage. - Document Laboratory Handling
Record the material name, batch information, receipt date, storage location, and relevant handling conditions according to your laboratory’s procedures. - After Opening or Preparation
Once the original sealed state changes, follow the product documentation and your laboratory’s validated protocol. Clearly label any prepared material with the preparation date, composition, and applicable storage condition. - Avoid Unnecessary Temperature Cycling
Minimize repeated warming and cooling. Avoid repeated freeze-thaw cycles when frozen storage is required by the applicable protocol. - Use Material-Specific Conditions
Storage requirements can differ between lyophilized, liquid, and prepared materials. Do not apply one temperature, solvent, or stability period to every product.

Frequently Asked Questions
Find answers to common questions about this product, its research context, Certificates of Analysis (COAs), ordering, and laboratory use.
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 Well Elevation 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 Well Elevation 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, extracellular-matrix remodeling, and proliferation. In practice, the categories overlap, especially for molecules like IGF-1 that behave in both ways.
