First of all, I would avoid taking nolvadex while on tren or when tren is still in your system. There is a chance that it can stimulate prolation issues. That may have been where the issue started. I would start by trying to lower estrogen, taking letro at 2.5mg for 3 days, Then backing down to 1.25mg ED for a few days. Then evaluate from there. See if there is any improvement. If you can get your hands on some caber, that could be of some help. .5mg 2x wk is standard. You might want to start out with 1mg just to get the ball rolling on your first dose
In the future, use adex or another AI to control estrogen, especially while on tren or deca
