What is the timeline of peak T levels per method of administration?

[Pacman]

I was wondering how long it takes the T levels to peak. Like if I inject 1 cc cypionate, do my levels reach the peak right after, or a day or two after from that specific injection? Same question for propionate and topicals...

Some very quick non-scientific internet searching seems to indicate that test levels with cypionate peak 48-72 hours after injection, and with propionate about 14 hours after injection.

And topicals?
