1testcyp sorry for the late reply mate, been busy with xmas/new year.
From my personal experience I have been fine with that HCG protocol and it didn't lower my response to LH, but I can't 100% say it will be the same for everyone. It seems like there's a lot of contradicting information/studies with regards to LH desentisation from HCG so it's hard to tell when or even if this would actually occur.
