My opinoion is 17 is too young, wait till your 20. That being said.......
First off I would front load, not pyramid, and as M18 said run sust and deca at least 8 weeks, clomid at the end- 3 weeks after last injection, I would choose armidex or liquidex over nolvadex, and again as M18 said, start it if the nips get itchy or tender.
Since it's you first cycle you should be able to use low dosages, and get good results.
