I would recommend HCG even on an 8 week cycle. weeks 2-8 @ 250iu 2 times per week will make things a lot smoother when it comes to recovery. The Arimidex is a must have on cycle but don't use it until you need it. Are you prone to estrogenic sides?
I would also add the TRS from Primorial Performance to the PCT. Somebody around here should have a coupon code for you. Then you can easily run your nolva more like 20/20/10/10 along side your Unleashed and Post Cycle. You'll find this setup to be VERY smooth.
