How to Use This Tool
Washout time is when a compound drops below 1% of peak concentration. This typically requires about 6.64 half-lives. The tool calculates when the peptide clears based on its half-life and dosing schedule.
Calculations assume steady-state pharmacokinetics. Individual factors like kidney function, body composition, metabolism, and injection site absorption can affect actual clearance. Always verify with appropriate testing.
Use the preset buttons above for common peptides, or check published pharmacokinetic studies for your specific compound. Half-life values can vary based on route of administration (SC vs IM).
Yes, as long as you know the elimination half-life. This calculator works for any compound with first-order pharmacokinetics. Results are estimates only — always verify independently.
