Get a serm to go with your HCG.
I haven't used hcg or done PCT in years, I just stay on 150 in-between cycles. But I was fond of started hcg a week or 2 after my last dose of whatever injectable gear I was running. I would do 500 IU every other day until a 5000 IU bottle ran out and then I would start my clomid. 25-50mg a day for a month or so.
You could also run a low dose of HCG all cycle and then 3 weeks after your last test and hcg shot start your serm.
Lots of people running both ways and they all seem to do just fine.
I probably wouldn't choose clomid any more tho. Enclomphine is better on side effects and I actually like nolvadex better then clomid as well.
I do think you may find 250mg pretty disappointing unless your someone with a spectacular drug response. A very basic first cycle is to start around 250 or 300 and progress your way up to about 500 over the course of a 12-16 week cycle.
Running 250 for 10 weeks, it takes about 5 weeks to hit peak hormone levels so for the first four weeks or so you're basically just on trt, then you got another 4 to 5 weeks where you're just a little above trt. I wouldn't expect much. Gain a couple pounds little bit of water weight strength will go up a little bit but I don't think you're going to see anything exciting happen
