Peak vs Trough Difference

Is there a commonly accepted experience here of how much higher your peak is vs trough. How do you estimate peak levels based off of trough?

You have to test peak and trough levels to determine the difference between the two. It will also depend on your TRT protocol, my peak and trough injecting EOD means the difference is very small as my levels are virtually static when compared with someone who injects once or twice weekly.
