How to read this protocol
The chart above shows the modeled blood concentration of each compound over the 20-week duration. Each compound accumulates toward steady state (roughly 5 half-lives). The peak-to-trough ratio within each dose interval depends on the injection frequency relative to the half-life.
Use the peak-trough estimator to see predicted levels at any point, or the clearance calculator to estimate washout after the protocol ends. The PCT planner estimates when to start post-cycle therapy.
Educational only. Not medical advice. Concentration values are modeled estimates based on population pharmacokinetics, not predictions of individual blood levels.
