I'd stick with Primobolan and Anavar only, if it were me, and I'm headed toward the triathlon path. Both drugs retain zero water, neither disturb hormone system or testicular function. A solid program of either drug, or eight weeks of one and eight of the other, will put on lean mass only, and gains won't disappear when you are done. Winny is okay but can come with more side effects.
I'd avoid all other drugs, especially test, the king of water retention. You want to run and swim while carrying a few pounds of extra water weight? Not me.
