Potency loss over time
Estimated potency retained (%) per storage condition. Hover the chart for details.
⚠ A structural estimate, derived from each compound's sequence length, cyclisation and oxidation-, deamidation- and light-sensitive residues. Indicative only — not lab-measured per batch.
Time in body
How much of a single dose remains over time, modelled from the terminal half-life. Illustrative — not a dosing tool.
Half-life ~4 min (human PK) · effectively cleared (~97%) after ~20 min (5 half-lives).
