Test E + Primobolan (12 weeks)
Lean-mass cycle: 500mg/wk Test E + 400mg/wk Primobolan (injectable methenolone). Primo is favored for quality muscle with minimal water retention.

How to read this protocol
The chart above shows the modeled blood concentration of each compound over the 12-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.
