I'm not arguing anything about shutdown. I'm stating that testicular shrinkage does not always occur, and definitely not with short cycles. Just because your test is supressed does not necessarily mean you are going to experience shrinkage. Many guys report minimal, if any, testicular shrinkage on standard test cycles. Of course they are supressed, despite the fact that they haven't noticed shrinkage.
...and truthfully, supression begins long before the 2 week mark, regardless of drug used, even Anavar causes quick surpression despite the common notion that Anavar does not do this.
Personally, on my Winstrol cycle that I did a couple years ago, I was on for a while during my cut and never experienced any shrinkage at all.
