you don't just inject 500mg of test into your shoulder then your body magically says 'oh shit I have lots of test here I should shut down my balls' ..
its the downstream effects that cause the shut down, not the presence of the drug or its metabolites itself.
things take time . it takes time for your body to use proteins and build more aromatase enzyme to accommodate higher test levels so it can make more estrogen.. it takes time for nandrolone to bind to progestin receptors and then for that to cause estrogen sensitivity and thus for that to then signal the pituitary to stop production of luteinizing hormone and then ultimately shut your test production down.
its the same on the back end .. the timing of when a drug clears your system and then you immediately need to start PCT is really not that relevant (unless your just trying to pct as fast as possible so you can jump on cycle again , in which case your better off just blasting and cruising)
so when you come off your cycle. just give it time and let all the processes down regulate and start your pct whenever you feel is the right time .. there is no text book start pct at thus and thus time based on what drugs you ran.
heck half the time I don't think guys even need a pct , but thats a whole other topic
