Wow....Tri, that old school HCG advice.
HCG will suppress you if taken post cycle. HCG is only good for prevention or revertion of testiclular atrophy. It will do nothing to restart your HPTA.
Also, your doses are to large. I would take 500-1000ius ED with 10-20mg of N-dex. If you must start post cycle, do it now. This will get your boys back to normal. Then 4-5 days after your last small shot of HCG, you will need to go onto clomid for 3 weeks. Clomid, once the atrophy has been reverted, will begin to work hard on restarting your HPTA.
Large doses of HCG can bring on a large conversion rate of estrogen, which is bad, even with N-dex. ALso, large doses can desensitize your testicles from your natural LH production, which is bad.
So, to summarize, take small doses, preferrablely during your cycle to prevent atrophy, but in a worst case, take it the last 2 weeks to revert atrophy, then jump on the Clomid.
I say take HCG in small doses every 4th or 5th day throughout ones cycle is to prevent the atrophy from ever setting in. Why wait until its there and try to fix it?? Prevention is the key
