Results will be difficult to guess at, especially that far into the cycle. I'm thinking you will have a pretty hard look, it will help with losing some subcutaneous water, it will certainly help retain whatever muscle you have already gained.
You can do it eod or ed. Obviously you will get more results taking it ed, but then you will be doubling your dosage as well. Personally, I think you'll be fine at eod.
It's your call about how you want to do your post-cycle therapy. Human Chorionic Gonadotropin (HCG) is not a necessity, but it seems to be growing in popularity to take it prior to stopping your cycle and following up with nolvadex. Clomid seems to fading in some people's minds due to all the negative sides it brings.
