Half-Life & Cadence
Get a dosing cadence recommendation from a compound's half-life.
Inputs
hours
ratio
Lower ratios = more stable plasma levels but more frequent dosing.
Recommended cadence
Every 8.0 h (≈ 2× per day)
Short-acting peptide. Splitting AM/PM keeps levels within the target band.
14 doses per week
This is a research-math heuristic only. Real-world cadence depends on the compound’s full pharmacokinetics, route of administration, and study protocol — not just half-life.
