Downtime...
Gyno is caused by a surplus conversion of testosterone into estrogen, and the issue here is that you did not react well to the prohormone. Don't use it again.
At this point any cycle is not a good idea until you get yourself naturally producing the maximum amount of testosterone possible. You made the right move going to the doctor about this, and take it easy until you know everything you need to about these two things:
Exactly what is the count of your testosterone levels
Exactly what is the count of your estrogen levels
After that information is recived, wait a few weeks (8-10) then go back and do the test again.
If there is no change, you may end up being eligible for a legal prescription to some form of testosterone, AND you will know whats going on with your estrogen conversion. This is the main culprit for your gyno. Basically, your body did not know what to do with the pro-hormone you ingested, then it turned it into estrogen and in the meantime depleted your natural testosterone levels.
Don't cycle. Go with what you are doing already, and do follow ups.
