I've read on the topic, and it seems to be a 50/50 split on whether or not this is beneficial.
Some say to run it with PCT to help the transition....some say to run it while on.

Initially, I was planning on running it while on...but here are some thoughts:

Adding HCG to a cycle increases estrogen conversion. (More sides, more likely to need AI)
Even though you've added HCG, you'll still be shutdown from the test!!

So if you're going to be shutdown from the test, why take HCG?
Logically, if one sends a signal to shut down the testes, and the other sends the signal to turn the testes on.......
Does the HCG actually turn the testes on...?

Wouldn't it be more practical to utilize the HCG during & after PCT?
I'm pretty torn between the two, as I've heard great arguments on both sides.
