Most will tell you to run T+D 2-1 ratio Like 400mgT 200mgDeca
But if you run caber .5mg 2X EW from first pin it illiminates the deca dik so you can run both the same dose
It is a strong misconception running T higher will keep labido up but the real ED prob is elevated progestin levels.
That will be a great cycle. Just stop the deca 3 wks before you stop the T.
