As with everything you may have to experiment a bit to see what works best for you, but if I was on that cycle, here is what I would do.
week 4 and 5, 500IU HCG dialy for the two weeks.
week 10 and 11, 500IU HCG dialy for the two weeks.
start clomid week 12 150mg/ed for 3 weeks.
The reason my HCG recomendations are so low is because large surges of HCG can desensitize the testis to LH, that is not something we want, especially if trying to get them back from atrophy.
On climid, many recommend nolvadex because it takes 20mg of nolva to do the same job as 150mg clomid. However, nolva seems to have a very detrimental impact on IGF01 levels so I think I would just stick on a heavy dose of clomid.
