i do HCG all thru out the cycle as small dosages (500iu weekly), then for PCT im a strong believer of clomid and aromasin. This has been proven over and over again to work. None of these supplements that are popular on this forum will do anything close to what clomid (or nolvadex, whatever you choose) and aromasin (or arimidex) will do for your recovery.
I know makes some people feel shitty, but fuck, it works.
edit, i also like to use creatine monohydrate when i come off.
