time of the blood test

labs are to be drawn between certain hours to insure testosterone is at its peak.thats assuming the average person sleeps from 10 pm to 6 am and bllods drawn at 8 am.but what is a person sleeps from 8pm to 3am and get bloods drawn at 9am wouldnt that be the same as person #1 having bloods drawn at noon.i ask cause i get up at 3am everyday and got my labs between 9-10 though i been up for 7 hours and my testosterone was 30% lower this year from last 740-495

Have you maintained the schedule you noted during the time you are on TRT? What is your protocol? Specifically, what time do you administer your testosterone?

wrong; T testing is always done in a trough, the lowest point between applications; right before the next application.

What you describe, morning blood draws, is the norm when testing to diagnose low testosterone - before the start of therapy.
