First question..

I realize test prop reaches its peak quickly and goes away, thusly meaning you need to inject around every other day.

But how long does it take until it actually kicks in? Test-E you have to inject every week... But it wont kick in until what, week 4 or 5? How long till prop kicks in and starts working?

Also, im ONLY comfortable with injecting into my upper glute area... If I use test prop that means I have 2 upper glutes to use. Do they recover fast enough to be used as frequently as prop needs?
