Two questions - DECA and Nolvatex

I was wondering if there was any way to clean DECA out of my system. I took a Cleanser previously but DECA remained positive. I took the DECA around 18 months ago, would it remain positive if I were to be tested next month?

Also, I would like to know the detection time for Nolvatex (Tamoxifen). I have researched this for a long time and I still cannot find its detection time.

Thank you very much in advance.

i think deca can be detected up to 16 or 18 months if im not mistaken.

Thanks a lot: one more quick question, can Caverject be detected in a drug test?
