2017 Cell study used 5 mg/kg intraperitoneal injection three times per week in aged mice, with treatment periods of several weeks the three-times-weekly dosing suggests the peptide maintains sufficient functional concentrations for at least 48-72 hours per dose (PMID: 28340339)
The peptide's unique ability to penetrate cellular membranes, interact directly with DNA structures, and influence transcription factor activity positions it at the forefront of genomic medicine and epigenetic research, offering unprecedented opportunities for investigating the molecular mechanisms of aging and developing strategies for maintaining cellular function throughout the lifespan
Another example is Receptor Grade IGF-1 LR3, which researchers speculate exhibits an increased affinity and anabolic potential while binding less to IGF-1 binding proteins (IGF-1BPs)
