Steroid Plotter Correct? Max Serum Test Release When Time = 0

@Madagascarspirit

Do you have any good sources listing values for these? Likely derived empirically.

Population Pharmacokinetic/Pharmacodynamic Modeling of Depot Testosterone...

Table 2:

Example of use:

Tool to Assess your TT Dose Response -- Percentile Curves

Key Terms: [image] Good reference (see chapter 6) and here. [image] [image] Example PK profile assuming castrate adult male (no endogenous T production at time zero on forward): Notice it takes time for the testosterone for build up to a steady peak / trough ~ 5 half lives): [image]

Input for spreadsheet:

Starting TRT Over Soon

Assumed inputs/parameters for the absorption/elimination PK model: [image] My pleasure and I hope you feel better soon.

Examples use apparent absorption half life of 8 hr and elimination half life ~4.5 d for test cyp.

The original crappy elimination only models with instantaneous absorption finally got replaced with the refined absorption + elimination over in the What is TRT thread further down.
