some good advice from the-det-oak there
clomid should be minimum 2-3 weeks after your last shot of anything long acting....so he should drop clomid and start hcg. The clomid will do absolutely nothing for him if there is any juice in hius system, which there still is at this point, thats why he should drop it and start hcg.
I would go with 1000iu eod as its active life is around 60 hours so eod works good at the end of a cycle for a good blast before starting post cycle therapy (pct)(that being said its best to run hcg during the cycle as well). As I said in another post, I've been on for up to 2 years and have run hcg all the way through with no de-sensitization....I run it 2x weekly at 500iu, when the 5000iu bottle runs out in 5 weeks I take 1-2 weeks off then do it again. I had 2 kids on heavy, long cycles like that, and came off after years with no lag in my recovery.
for post cycle therapy (pct) clomid and nolva together works great, much better recovery than just running one or the other, plus the nolva will help with any post cycle estrogen rebounds.
and anyone whose source says to run hcg and clomid together needs to find another source who isnt just trying to sell him extra stuff along with a line of bullshit
