Sounds like things are in order. Drink plenty of H2O, nail your woman really hard, and go rip the doors off of your gym. Think about all the new clothes you will have to buy with the lean mass you'll pack on.
I asked about the anti-e because I've heard of people getting *****y in the first few days of a cycle because they didn't control estrogen levels.
Things will pick up. Your test levels will be greatly elevated within hours of the injection. You should notice subtle effects (hard-ons, mood, motivation, etc.) very soon, but muscle gains take a little longer. Enjoy.
