I have read that Test level while not on aas will drop after 45 minutes of training. At that point your bodies cortisone levels begin to increase. So by 60 minutes into the workout, and individual should have completeed their training, because at that point on continuing does more harm than good.
My question is in three parts:
How long do test levels stay up and cortisone suppressed with test/ or other aas?
What are the determining factors in regard to how long test levels stay up?
Does the ester of test make a difference?
