Its impossible to answer really, everyone is different and you will just have to find out.
I will say your doses are very low. 250mg test and 75mg tren is next to nothing, certainly not the supra-physiological doses most associate with a steroid cycle. If you are going to shut down your body and are not on long term TRT, I would surmise it may not even be worth it to go that low.
I would recommend 500-600mg test and 300-500mg of tren weekly. Others prefer high tren low test, but not me (200-300mg test 600-800mg tren).
If your tren is acetate rather than enanthate then you should be prepared to pin EOD at least, preferably ED to keep blood levels stable to mitigate sides and divide your test up accordingly to go with it. Even with the longer esters, your blood levels remain more stable with more frequent injections.
I and most would recommend HCG during cycle, not after. Best to prevent testicular atrophy than rectify it.
Also it would be wise to use an AI during cycle, the aromatisable test will amplify the tren sides. Furthermore you always should use an AI anyway with anything aromatisable.
