HCG is awesome. Keep your balls functioning so that you do not have to wait for them to grow back when you come off cycle. How fun do you imagine it will be to walk around with sub 200 test levels, and not even a decent pair functioning testicles. Limit or avoid time spent in that situation. Do yourself a favor and get some HCG at least for the tail end of the cycle.
Cons
$, effort
Pros
Keep gains, Less time feeling like **** during pct, peace of mind knowing that you are taking care of your health and preserving your reproductive capabilities,
