it doesnt matter what time of day you inject the oils. you just want to stay consistent on taking them on the right days to keep blood levels stable. test e should be split up into at least 2 times a wk and NPP should be split up into EOD shots. with the tbol, i would split it into 2 doses per day to keep levels steady. 

most steroids aren't going to hit you with one dose. the key with your dosing is to get your blood levels stable. this will reduce the likelihood of as many side effects. many sides can be from a fluxuation in hormone levels. i've found that when i miss doses or don't use a particular ester frequently enough, i am more likely to get acne or sensitive nipples. with tren, i used to suffer from side effects on 100mg EOD, but when i moved it to 50mg ED, the side effects reduced dramatically. i sleep fine on 50mg ED, experince no moodiness and acne is nonexistent.
