The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.
THIS PRODUCT IS NOT INTENDED TO TREAT, CURE OR DIAGNOSE ANY CONDITION OR DISEASE AND IS NOT FOR HUMAN CONSUMPTION. ALL PRODUCTS OFFERED ARE INTENDED FOR LABORATORY RESEARCH USE ONLY.
All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

IGF-1 LR3 is a laboratory analogue of insulin-like growth factor 1. Its modified structure is examined in controlled research involving IGF-1 receptor interactions, ligand-binding characteristics, and downstream signal-transduction pathways.
In vitro studies may use IGF-1 LR3 as a reference material when comparing native and modified IGF-related compounds. Laboratory variables may include receptor-binding measurements, concentration-dependent assay responses, exposure intervals, phosphorylation markers, protein-expression measurements, and other protocol-defined endpoints.
IGF-1 LR3 may also be included in comparative assay designs evaluating how structural differences influence ligand behavior under standardized laboratory conditions. Reproducible research requires suitable controls, validated analytical methods, documented storage, and consistent material handling.
Important Research Notice: Each lot is subject to independent third-party analytical testing. Available documentation may include HPLC purity analysis and mass spectrometry identity verification. Consult the lot-specific Certificate of Analysis for confirmed results and testing methods.
THIS PRODUCT IS INTENDED EXCLUSIVELY FOR LABORATORY RESEARCH. NOT FOR HUMAN OR ANIMAL CONSUMPTION OR IN VIVO PROCEDURES. NOT FOR DIAGNOSTIC, THERAPEUTIC, VETERINARY, FOOD, COSMETIC, OR SUPPLEMENT USE.
IGF-1 LR3 may be evaluated in controlled in vitro assays examining IGF-1 receptor interactions and downstream signaling events. Laboratory measurements may include phosphorylation status, pathway-associated protein expression, transcriptional responses, and time-dependent assay changes.
Protocols should incorporate appropriate controls, defined exposure conditions, and validated detection methods. Results must remain limited to the selected laboratory model and analytical procedures.
Laboratory studies may use IGF-1 LR3 to examine pathway-associated protein synthesis markers and cellular assay measurements under controlled culture conditions. Research variables may include exposure duration, concentration range, cell type, media composition, culture density, and baseline assay conditions.
Standardized controls are necessary to account for serum composition, cell-cycle status, culture conditions, and other variables that may influence the measured data.
IGF-1 LR3 may be included in ex vivo or laboratory tissue assays examining receptor-level interactions and related molecular markers. Applicable endpoints may include receptor binding, pathway activation, transcriptional changes, protein-expression measurements, and laboratory-defined structural observations.
Separate experimental groups and appropriate controls should be established when comparing IGF-1 receptor activity with other signaling systems. This reduces confounding variables and improves data interpretation within the selected research model.
IGF-1 LR3 may serve as a reference or comparator material in multi-compound in vitro studies. These experiments may evaluate differences in receptor-binding characteristics, signaling duration, pathway selectivity, and assay responses across individual research compounds.
Material identity, lot traceability, storage records, and standardized analytical procedures are essential when comparing results across study phases. Each research material should be evaluated independently before additional experimental variables are introduced.
Each lot of IGF-1 LR3 is accompanied by a Certificate of Analysis documenting the available analytical results. Depending on the lot and testing protocol, documentation may include:
The applicable COA should be retained with procurement records, inventory documentation, protocol files, and internal laboratory quality-control records.
Laboratories sourcing IGF-1 LR3 should evaluate product labeling, lot identification, storage information, analytical testing, documentation availability, and material traceability.
NordSci Peptides supplies IGF-1 LR3 as a laboratory research material with independent third-party testing and lot-specific COA documentation. The product is intended exclusively for qualified laboratory, analytical, and institutional research settings.
