I've no clue what test e q3-4days means but I'll take a shot in the dark.
Prop isn't going to do shit for you on workout days, the prop ester releases the test into your system is over a few days. Your best bet is to take your prop everyday, it's a low bloat ester but the pin count is high.
Testosterone Suspension is the fastest acting test, you will get the kick right now, but you will be a pin cushion if you want to keep your syrum levels normal with that stuff.
