I think 30mg/day of Var for 6 weeks is an excellent cycle if you've got the cash for it. It's best to stay away from winny if you might get tested; it's been known to hang around in the system a long time ala Ben Johnson.
I don't think you'll need the nolvadex during your cycle since Var does not aromitize to estrogen. Many men throw HCG in the last two weeks of a cycle to get the testes ready for PCT but I doubt you'll need it during a 6 week Var cycle.
I typically use 40 mg/day of nolva for 3 weeks as PCT but again, because Var is not all that supressive to testosterone production, you may get away with less. However, nolvadex is cheap and 40 mg won't hurt you.
