Monitoring protocols typically include baseline measurements of relevant biomarkers before treatment initiation, followed by periodic assessments during and after peptide administration
The fatty-acid chain makes the molecule strongly retained, so it elutes late and needs a high organic proportion, and the peak is broader than a short peptide's peak because oligomeric species interconvert on the column timescale
Like many therapeutic peptides, it may require daily (or near-daily) administration, as in the previously referenced mouse and rabbit studies.12 17 Moreover, as a preventive or a drug for managing chronic health conditions, treatment ought to be ongoing and may involve periodic breaks in dosing (cycling), which is also common with many therapeutic peptides
