dbol estrogenic metabolites hand around for a while (how long has not been thoroughly tested)- though likely not more than 3-4 days.
nolva has a half life of 7-10 days, apprx 14 days with extended use (3-4wks).
nolva is an estrogen , it is a mixed agonist/antagonist of the receptor (SERM).
many of the mood issues that occur after cessation of PCT are likely due to high blood levels of the SERM used (clomid has a half life of 5 days, which also extends with use)
