As for your dose of cyp and tren e, it all depends on what your experince level is. If you are a new steroid user, you will make all the gains you can possibly make in one cycle, on 500mg of test a lone. You don't need to add other compounds, especially tren. If you have completed several cycles, 500mg test along with 400mg tren e would be acceptable. Really though, if you have done several cycles and are going to try tren, you'd be best off using tren ace. It's easier to manage as the half life is much shorter. Tren ace at about 75 to 100mg EOD is pretty standard. Be sure to do a complete PCT after your cycle.
As for your friend...Sorry, but no one can gain 25 lbs of muscle in one month and no single cycle will get someone into pro bodybuilding size and shape. Even the guys with the best genetics take years to reach that level. So don't be fooled into thinking that taking a specific drug (or combo of drugs), will transform you or anyone into a pro over night. Tren is a popular drug and a lot of guys like to use it. You can find message boards filled with guys who have done many tren cycles and still don't weight 200 lbs lean. Further, don't compare your progress to anyone else's. We all grow at different rates. If you continue to reseach how to keep improving your diet and training, while using as little gear as it takes to evoke a strong effect, you will get to where you want to be (asuming you have realistic goals)
