When you use any steroid, your HPTA will be suppressed. What this means is that your system is not producing any endogenous testosterone, which means you won't have any hormone to help maintain your gains. What good is a cycle if you can't keep your gains? So the key to cycling is to get your endogenous test back on track ASAP.
So given that, here is the universal post-cycle recovery program:

HCG
2 Weeks Before End of Cycle: HCG @ 1500IUs 3 times a week
1 Week Before End of Cycle: HCG @ 1500IUs 3 times a week
First Week Post-Cycle: HCG @ 1500IUs 2 times a week

Clomid
Day 1 Post Cycle: Clomid @ 300mg
Days 2-14: Clomid @ 100mg ED
Days 15-28: Clomid @ 50mg ED

Nolva
Days 1-28: Nolva @ 20mg ED
cheers.
