The prefilled numbers are an example input to draw the curve, not a dose; Pedplot does not suggest one. To step a dose up, add another row of the same compound with a later start day.

HCG. Plotted in IU, not milligrams. Do not add this line onto a milligram total. There is no ester, so the line is the dose itself. Also called Chorionic gonadotropin.

Pregnyl SmPC (Organon): apparent elimination half-life ~33 h (IM or SC); peak ~6 h after IM injection in men. How the model works.

The example curve

500 iu every other day for 12 weeks. With a 1.5d half-life, it levels off around day 8. The row runs longer than that, so the plateau is on the chart. Between doses it runs from about 369 to 829 iu, a swing of 55%. Each dose is its own spike. After the last dose, the tail takes about 8 days to fall to a few percent.
