You probably have a little test flue. I have no idea what you're talking about here, pct on week 4? You use nolva if you get gyno perhaps but why would you ever pct after only 4 weeks? Especially with test (e).. your cycle has just started to kick in. I'm not gonna tell you to continue a cycle but if you decide to pct cause you're out of energy then you better just quit the cycle all together. I don't think you've really read up before starting this cycle and now you're worried. This I why you should always have the knowledge before you start a cycle. If it is test flue nobody can tell you when it stops, it's a normal flue but it's called test flue cause we tend to get sick easier in the beginning of a cycle. One day, one week, it's impossible to tell. My bet would be 3-5 days.
