I have been using
Androgel on a daily basis. How will the timing of this
Androgel application affect blood
testosterone measures? Will it make any difference what time of day my blood
test is in relation to the Androgel application?
If I were to stop using Androgel, how long would it take for a signifcant difference to appear on the blood
test. Would 36 hours make a difference? How much of a difference would 60 hours make?
The documentation for Androgel gives some basic information on these issues. In states:
"Serum concentrations approximate the steady state level by the end of the first 24 hours and are at steady state by the second or third day of dosing."
"When AndroGel treatment is discontinued after achieving steady state, serum
testosterone levels remain in the normal range for 24 to 48 hours but return to their pretreatment levels by the fifth day after the last application."
