Welcome, take it from another 6ft 175lb guy... you're gonna want to do longer than 10 weeks.
I just started my very first cycle... about 4 weeks ago now. My cycle is 300mg per week, 150mg on Monday, 150mg on Thursday. I'm already looking into turning it into a 16 week cycle. The first 2 weeks not much happens. The beginning of the 3rd week is when you start to feel the effects, and the 4th week is when visible differences start. Now I only have 6 weeks left
.
Plus running a pretty mild dose of 250mg, a 12,14, or 16 week cycle is fine.
Also just as long as you have your pct stuff on hand, you can cut it short the second you start getting nasty sides(if any do occur) So if you plan on a 16 week, but 13 weeks in you start getting bad water retention, gyno, whatever... stop and wait the 4 weeks to start your pct. Worse case you just have some leftover test for your next cycle.
The Only other advice I can give from one newbie to another is diet! It's so important, especially on gear! You have to eat to grow, and you have to eat right.
Good luck brother!
