A single-component research material supplied for controlled research environments. IGF-1 LR3 (0.1 mg) is a recombinant analog of Insulin-like Growth Factor 1 featuring an arginine-to-glutamic acid substitution at position 3 and a 13-amino acid N-terminal extension, studied for its potential role in IGF-1 receptor signaling, cell proliferation research, and metabolic pathway exploration in model systems.

• Accelerated Muscle Growth (Hypertrophy): IGF-1 LR3 promotes the proliferation and differentiation of muscle satellite cells, aiding in the creation of new muscle fibers and greater strength gains.
• Enhanced Recovery & Healing: It speeds up the repair of muscle tissue, tendons, and ligaments, making it effective for recovering from injuries or intense training.
• Improved Body Composition & Fat Loss: It helps decrease body fat by increasing metabolic rate, promoting fat oxidation, and improving nutrient partitioning (how the body uses food).
• Long-Acting Anabolic Effect: Unlike natural IGF-1, the LR3 version is modified to resist breakdown by binding proteins, allowing it to remain active in the body for 20-30 hours.
• Enhanced Nutrient Uptake: IGF-1 LR3 increases glucose uptake and insulin sensitivity in muscle tissue, leading to better glycogen storage.
• Anti-Aging and Cognitive Support: It may help combat age-related muscle wasting (sarcopenia) and support cognitive health by protecting against neuronal loss.

Documentation & Quality Assurance

Each lot is sourced through our verified global supply chain with emphasis on traceability and quality control. We work diligently to obtain and maintain third-party analytical reports (HPLC/LC-MS) and Certificates of Analysis for each batch, as part of our ongoing quality process. These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications.

Quality & Manufacturing

All materials are sourced from carefully vetted domestic and international manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing. We require a verified purity of 99% or higher and perform independent third-party spot testing to confirm that select lots meet our internal standards for identity, purity, and composition. Where available, endotoxin testing results are included on Certificates of Analysis to verify laboratory purity; their inclusion is for research quality assessment only and does not imply suitability for human or veterinary use. All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery.
