N1tro,
I agree with you to a point. PCT has a lot to do with it and you will almost always retain at least some of what you gained through a cycle, no matter how slight. However and speaking from my own experience, I just retain my gains better on some types of gear then on others. For example, I once did a cycle stacking adrol with cyp. Even though I was still on the cyp, shortly after the supply of adrol was gone so were the gains I received from it. I still had the effect of the cyp, but the adrol gains were as though they'd never been there. Same thing w/ dbol. It's great while I'm on it but as soon as I'm done... so are the gains. Very difficult for me to keep. And my PCT is always the same. Nolva. I know that's not as good as HCG and not an ideal PCT but the fact that I retain gains from some gear better than others on such a PCT goes to show that I would retain gains from those particular types of gear more so than others regardless of how good the PCT was.
Now, I have no practical experience with EQ. I know just what I've read. My question would then be what is it about EQ that makes the gains so retainable? Perhaps I'll never know the details. Another thing I know is that some don't like EQ by itself and some swear by it. I won't know until I try. There's no teacher like first hand experience.
