when taking something like VAR or Winny (dependent on dose) the suppression is minimal (compared to other drugs). so lets assume 20mg of Winny per day. suppression may be at 40%. he is still producing natural test, but in very small amounts, and the amounts are small enough that estrogen and Dht conversion also go down (thus he will feel very suppressed). but he is not totally shut down. he is still producing natty test.
NOW lets say he takes 500mg of test and 500mg of Deca. his suppression will likely be near 100%. this is because the HPTA gets hit from many different angles. he is shut down from not just taking exogenous androgens, but he is also shut down from the high estrogen conversion from the test, and he is also shut down from the progestin properties of Deca (prolactin/pregestin shuts down hpta the hardest).
make sense ?
the whole idea that a new user after one shot of testosterone is shut down is forum urban legend. shut down does not work that way. its progressive over time depending on many factors. in fact a guy on his first cycle of test is likely, when injecting test, adding onto his natural test production as well for several weeks or more, until estrogen and other things are elevated and further suppression sets in.
its NOT like your body magically feels an injection of steroids and then suddenly shuts down natty test production.
thats also why there are ways to run oral only cycles, especially with DHT based compounds like VAR and Winny and not have to run exogenous test or do much of a PCT. because shut down is minimal compared to other cycles.
having said that,, running exogenous test and doing a real pct are of course optimal
