I am just throwing this out there. It is just an idea.
Many here report crashing days or weeks after quiting.
People blame the return of DHT. But we know what effects DHT itself has on the body and it should not cause PFS.
So perhaps the crash could be related to another 5a reduced metabolite which is not so androgenic?
Maybe something say like 5α-Androstane-3β,17β-diol?
en.wikipedia.org/wiki/5%CE%B1-An … CE%B2-diol
5α-Androstane-3β,17β-diol, also called 3β-androstanediol, and often shortened to 3β-diol, is an endogenous steroid hormone. It is a 5α-reduced and 17β-hydroxylated metabolite of dehydroepiandrosterone (DHEA) as well as a 3β-hydroxylated metabolite of dihydrotestosterone (DHT). Similarly to DHEA, 3β-diol is a high-affinity full agonist of the ERβ, and hence, an estrogen. In contrast, it does not bind to the androgen receptor.[1] As a result of activation of the ERβ, 3β-diol has antiproliferative effects against prostate cancer cells and proliferative effects on breast cancer cells.[2][3]
A determination of the circulating levels of 3β-diol in humans found concentrations of 239 ± 76 pg/ml and 82 ± 45 pg/ml of the compound in normal male and female serum, respectively.[4]
