What the chart measures

The Y-axis is estimated remaining active amount after half-life and ester weight. It is not a blood level in ng/dL, and it is not a blood test.

What this page does not do

Pedplot does not sell or help anyone obtain a compound, and it does not say what to take. Read the disclaimer.

Peak, trough, and washout

Peak is the high point of the line, trough is the low point before the next dose, and washout is how long the line takes to fade after the last dose. The methodology defines each one.
