I have always used a taper both up and down. I know its old school but my body likes it better.
Prone to acne it sure does help.
I always start with 500, then 750, then 1000, 1250, 1500 and then down again after 16-30 weeks.
With my tren i start 50, 75, 100 then down closer to end.
Var\winny etc dont seem to bother me like the other drugs do.
Its a little more complicated when your already on, then add in a drug etc. In most cases my base is stable before I add any other compounds.
Hope that helps.
FYI your cycle layout looks fine, you can up the test and add in the tren.
