Test is test - although we do like to stick to test e or C for first timers... However, I myself used prop my first go around.
Most will tell you about props debilitating PIP(post injection pain) and others seem not to have the issue(either way you'll feel it in a virgin muscle)!
I think you can get away with sust for a first cycle(but it's got 4 esters in it) propionate/phenyl propionate/isocaproate/& Decanate) so it goes shortest/short/long/longer(Decanate 21 days post injection to start PCT)
