Is this your first cycle? Post with stats/training experience and all the other crap the stickies say you need to post with.
SERMS like clomid and nolvadex are not the best on cycle. That is the job of an AI like adex/letro. SERMs are best post cycle.
5 weeks is not long enough, in my opinion.
Bonez, or anyone else more with more knowledge than me could tell you better.
It sounds like you need to take a few months tops to research. Read all the stickies on here. That is a good place to start.
