300mg Test E Weekly ( Sides )

Today started my PCT journey per this guide: HPTA Restart- Easy Guide. I have some questions.

  1. When do i know it is enough for me of part1? ( Do i need to test LH / FH )
  2. If my E2 is out of control, can i use armidex / nolvadex during this period if needed ?
  3. In Part2 is it necessary to use 600iu or 500iu is enough ?
