Benefits (Research Focus) IGF-1 receptor activation studied for selective high-affinity agonism of the IGF-1 receptor PI3K/Akt/mTOR signaling investigated for downstream activation of cellular growth and protein synthesis pathways Reduced IGFBP binding explored for the Arg substitution that decreases IGF-binding protein affinity Extended half-life examined for ~20-30 hour bioactivity window compared to ~15 minutes for native IGF-1 Skeletal muscle research researched for satellite cell activation and protein synthesis endpoints in preclinical models What Researchers Look At IGF-1R binding affinity and downstream phosphorylation cascades (IRS-1, Akt, S6K) PI3K/Akt/mTOR pathway activation in muscle and metabolic cell models IGFBP-3 binding affinity and free fraction pharmacokinetics Skeletal muscle protein synthesis and satellite cell activation endpoints Comparative bioactivity versus native IGF-1 and other IGF-1 analogs in cell-culture systems Quick Specs Form: Lyophilized white powder Net Peptide Content: 1 mg per vial Quantity: 1 vial Appearance: White to off-white lyophilizate Reconstitution: Bacteriostatic or sterile water (added by the end researcher) Purity: 99% by HPLC Identity: MS-verified (per COA) Storage: Protect from light Identity Basics Compound: IGF-1 LR3 (Long [Arg] Insulin-like Growth Factor-1) Synonyms: Long R3 IGF-1

Freezing and thawing can damage the peptide structure

Unlike most antioxidants, which work only in specific environments, glutathione is active throughout the body

Its designed to work through coordinated activation of GLP-1, GIP, and glucagon pathwaysmechanisms commonly associated with appetite signaling , energy utilization , and broader metabolic balance
