I'm sure I'll get flamed for saying so, but I think prop is a really bad choice for a 1st cycle.
Sorry to join the chorus but, "You should have got Enth or Cyp"...
I'm sure I'll get flamed for this too, but if you use the prop anyways, I'm guessing it would be nice to kick-start the cycle for the first 4 weeks the same way other people use d-bol (since it's so fast acting).
