Technical experts, and blood tests aside 1 week with PCT is not going to do anything. 4 to 8 weeks of 20mg nolva, or 25mg of clomid (one or the other, not both at the same time).
I personally PCT until I have a decent libido, and morning wood, taper off for a couple of weeks with a half dose/day. The reality is most guys natural production is going to be less than pre steroid levels, especially when off PCT drugs.
I would do another PCT course with a serm like nolva or clomid.
I have gone back on cycle before my levels were in the normal range or very low normal. Done a longer PCT the next time and got into a decent range before starting again. People can respond differently so you need to find out what works for you.
