Editorial policy
HalfLifeDB explains pharmacokinetic concepts for general education. Each substance page pairs a simplified elimination model with source links.
The project is designed to be transparent about assumptions. We do not present the calculator output as a prediction for any individual person, and we avoid content that would encourage risky behavior.
How pages are written
- We focus on explaining what a half-life estimate means and what it does not mean.
- We avoid providing dosing guidance, treatment advice, or instructions that enable harm.
- We describe model assumptions and common reasons real measurements may differ.
How half-life values are selected
Half-life values on HalfLifeDB are used to drive an educational curve. Many substances have multiple published estimates depending on study conditions. When multiple estimates exist, we choose a representative value to illustrate the curve and include source links so readers can review context.
We do not attempt to reconcile every study design difference, and we do not offer individualized guidance. When new high-quality references are identified, we may update the value or add clarifying notes.
Sources
Source links are provided so readers can verify information and explore primary literature. Where possible, we prefer reputable medical and scientific sources such as peer-reviewed journal articles, textbooks, and official product labeling.
Corrections
If you believe a page contains an error, email admin@halflifedb.co with the page URL and what you think is incorrect. If a correction is warranted, we will update the page.
Content scope
- Included: educational explanations of pharmacokinetic terms and simplified decay curves.
- Not included: instructions to evade testing, dosing advice, sourcing, or facilitation of illegal activity.
- Not included: diagnosis, medical decision support, or emergency guidance.
Updates and versioning
Pharmacokinetic estimates can vary by study and context. We may update values or notes as better references are identified. The goal is to keep entries useful as educational summaries, not to provide personalized guidance.
