A compound's half-life is how long it takes for half of it to clear. Pick one below to see how it decays over time — built on published pharmacokinetics with PMID citations.
About 0.1 half-lives elapsed
This is exponential decay based on the published half-life — it shows how a compound clears over time. It does not indicate when or whether to dose. Not medical advice.
After each half-life, half of what was there is gone. This pattern is the same for every compound — only the length of one half-life changes.
Educational only — not medical advice. Half-life describes clearance, not when or whether to dose. Individual pharmacokinetics vary; published figures are population estimates and some are from preclinical data. Research peptides are not approved for human therapeutic use. Consult a licensed healthcare provider.
