Hcg after pct

hey guys

i'm curently on my 7th day of clomid and i'm using a 300/100/50 method dosage. i wanted to run some hcg after i was done the clomid to give my sex drive a boost(i've never used it before) how long should i wait before i use it

i know hcg is usually supposed to be run in the last few weeks in a cycle however as you can see its too late. can i any benefit from using it a couple of weeks after my pct is done or am i just wasting my money. thanks

oh yeah and is it okay to run letro(want to clear up some gyno) during the hcg or should i wait till its done. i know there are certain drugs that counteract each other.. just need a little help clarifying this. thanks to all those who take the time to answer this
