From what you have written it appears that you have very little understanding of the drugs you are using. You should spend some time educating yourself - There are some threads in this forum that are a good place to start.
I have never used deca and for a first cycle i think it is a terrible idea. You might need something to control prolactin. Also i think it has a longer half life than the test so you stop using it a week before the test. Stop deca 3 weeks before pct and test 2 weeks before pct. As i mentioned i have never really looked into using deca so i am not 100% on this.
You also need an Aromatase Inhibitor to control your estrogen.
HCG is best used during the cycle not for PCT. 250iu 2/week
If you ran the clomid @ 50mg/day you won't have enough to even do a 3 week PCT. 4 weeks should be the minimum, 6 would be better. You might be able to run the clomid @ 25mg/day but i use nolva so do not know how effective this would be.
My advise would be to stop the cycle now, research AAS so that you understand how the HPTA works and how these drugs affect it and whilst doing this improve your physique naturally. Given your current stats you have loads of progress to make before considering AAS. 185lb 6'1" @ 15% is not a good place to start from and steroids will not help you if you do not have the basics of diet and training in place.
