You might want to be a little clearer and you wouldn't get trashed so much.
From what I have read so far you want to know if DHEA is going to fuck up your cycle.
The answer is no.
I have been using DHEA for 6 months now for the following reasons:
Basically I researched the drug due to the coming ban that the gov't is attempting. It is very cheap, is known to prevent the effects of aging (I'm 35) and in some studies has been shown to help with fat loss.
I am also in my 4th week of a Test E, EQ cycle and I am growing and becoming very strong.
SO, with me anyway, it has no effect on my cycle.
FYI: On the subject of using DHEA for PCT....
I also looked around and their is a lot of talk about the drug and using it for this reason, BUT, I talked to a couple of vets here on the subject and to quote my good freind BUSHBOY:
"Why not use something that has been proven time and time again instead of trying something else. Clomid and others work. There is nothing out there that says DHEA does."
You mentioned you were taking 300 mgs of nandrolone per week. This to me is not a cycle its a waste of time.
Just some thoughts, try if you want, and try getting your point across quicker.
