Contest Prep Drug Recommendations

Hello All, I have used this site for information for the last couple years and I just joined the forum. I am less than four weeks out from my first bodybuilding competition! I have never used AAS, so my size won’t be my strong point but my balance is pretty good IMO and I would like to come in the show absolutely diced, dry, and full. It seems letrozole is the way to go.

A few important questions:
I have suggestions from mildly-experienced friends of 1mg daily up to the show but I read that the effect can be optimized at .25-.5mg, and I only weigh 150lb (if that matters). Would those dosages most likely be sufficient? I feel more comfortable with that as to minimize sex-drive-loss and potential estrogen rebound. Am I incorrect in that assumption?

Also, I have clen and nolvadex. I ran two weeks of clen and may run another, but only if there’s no reported reason I shouldn’t mix clen and letro. Is there? (liver stress, blood pressure, etc.)

And possibly the most important question: I would like to use nolvadex post-letro to limit estrogen rebound so should I start that immediately afterward, and are there any suggestions on this concept?

Thanks to everyone for the information I’ve already read but I cannot find these answers anywhere on the net.
