Tools & Calculators

Half-life tracker

See modeled peptide activity and clearance based on your injection logs.

3 min read

The half-life tracker estimates relative activity over time from your logged doses and published half-life parameters. It’s a planning visualization — not a lab measurement of blood levels.

Half-life activity tracker
Activity curves help you visualize spacing between doses.
  1. 1Log doses normally so the tracker has real timestamps.
  2. 2Open Tools → Half-Life Tracker.
  3. 3Select the peptide(s) you want to review.
  4. 4Use the curve to reason about spacing — then confirm any changes with your clinician.

Model, not measurement

Curves are educational estimates. Individual metabolism, formulation, and clinical context always matter more than a chart.
