.25-.5mg arimidex, 25mg Aromasin E3D, 10-20mg Nolva, or maybe 50mg Proviron would suffice for proper estrogen maintanence. Take your pick..mine would be Aromasin and Nolva together.
Your cycle looks good. Extend out that Test and Deca to 10wks. Sust vs Testoviron...doesnt matter, get whichever is cheaper yet still good quality.
