I assume that yes,using HCG will help alot.
But not sure it will be enough,on my last cycle I did Test Cyp and after a while decided to add soem Tren.
I was using HCG throughout then ,after one or two Tren shots I felt my libido drops right away.
Seems that Tren > HCG+Test (at least on the dosages I used). Might be just me though.
