How To Know That Your Test Production Stopped?

Im interested,which lab test shows you that your balls stopped producing test? That you need bit of hcg.

Also,would a Nolva only pct of 4-6 weeks be enough if e2 is a bit higher and test low(at the end of the cycle,15 days after last pin)?
Would it be enough to keep e2 in range and bump up natural production of test?


This is what I’ve done in the past
