Post PCT test levels

I'm just curious to find out

Is it possible to get your natural testosterone production to be stable at higher count than before you did a cycle. lets say your count was 500ng/dl pre-cycle and then after following a good pct have a natural level of lets say 550ng/dl? Or is it that your natural test production can never be upped and if your bodies normal is 600ng/dl that even with a perfect pct you will never get it above that?

Your natural levels are always changing and often 'stabilise' at different concentrations...

Your testosterone levels also fluctuate throughout the day and are generally highest in the morning. So if you want to do a test before a cycle and then again after PCT it is best to get both tests done at the same time of day, after a good night's sleep to get an accurate comparison.
