See all certificates of analysis Storage & handling Peptides are photo- and temperature-sensitive; handle per standard laboratory practice. Lyophilized storage: Keep the sealed vial cool, dry, and protected from light. For longer-term storage, freezing is standard practice for lyophilized peptides. After reconstitution: Refrigerate (approximately 2–8 °C) and follow your institution’s SOPs for aliquoting, handling, and disposal. Avoid repeated freeze–thaw cycles. Diluent not included: A suitable laboratory diluent and reconstitution supplies are not provided with this product. UV-resistant glass vial to help protect photo-labile peptides during storage. Tamper-evident seal to support chain-of-custody and inventory controls. Sourcing & quality Why source IGF-1 LR3 from Sports Technology Labs Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products. Independent verification of identity and purity is essential for reproducible research. Third-party tested & certified Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs. Lyophilized & packaged in America Freeze-dried into sterile, UV-resistant glass vials and packaged in the USA. Tamper-evident packaging Supports chain-of-custody, label transparency, and batch-linked traceability. 60-day money-back guarantee Transparent business, standard payment methods, no misrepresentation. Research context What is IGF-1 LR3? IGF-1 LR3 (Long R3 IGF-1) is a synthetic analog of insulin-like growth factor-1 (IGF-1). It differs structurally from native IGF-1 in two ways: an arginine substitution for glutamic acid at position 3 (the “R3”), and an additional 13-amino-acid extension at the N-terminus (the “Long”). These structural modifications reduce the molecule’s binding to IGF-binding proteins (IGFBPs) and extend its half-life relative to native IGF-1. Mechanistically, it binds the IGF-1 receptor (IGF-1R). It is used as a research chemical to investigate IGF-1 receptor signaling in experimental models. IGF-1 LR3 is an experimental research chemical, supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals. Regulatory & compliance status Important regulatory information Not approved for human use IGF-1 LR3 is an investigational research peptide. It is not approved by the FDA and is not a drug, food, dietary supplement, or cosmetic. Marketing it for human use is unlawful. WADA-prohibited Insulin-like growth factor-1 (IGF-1) and its analogues are prohibited by the World Anti-Doping Agency at all times under S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics) (ref. 3). Legal status for research In the United States, IGF-1 LR3 is not a controlled substance and may be legally purchased and possessed for laboratory research use. Other jurisdictions may regulate it differently. Our position Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
