Your cycle logic is flawed.
Why is the cycle so short?
The masteron will lower the shbg so IMO drop the winny or masteron.
IMO shbg may not bind to trenbolone very well so i wouldn't worry about shbg.
Test prop 100mg ed 10wks
Fina 75mg ed 8wks
Masteron 50mg ed as you see fit.
Add an aromatize inhibitor.
