I wouldn't use the deca If I were you, on such a short cycle. Nandrolone phenylpropinate would be a better choice, however, even test prop/ enanthate would probably be better in this cycle. The problem with your stanfina is not the winstrol, it is the tren, which is just a base without an ester. Blood levels will not be steady. I think you will make gains off this cycle, but in the interest of a fast recovery, ditch the deca, and get something else in its place. Using just oral winstrol, and Tren Acetate would be a much better choice, but from the sounds of it, you have already picked up your gear.
