id go 50mg var for the last 4 weeks. it’ll give u that extra strength boost right when the fatigue starts hitting from the deficit. 600 test is plenty of base for that too

careful with the "feel good" part haha- sometimes mast makes me a bit too aggressive in the gym and i end up hurting something. just listen to your body and enjoy the gains. id definitely save the var for the finish

honestly 600/400 is a big boy cycle lol you’re gonna look like a beast. i’d do 40mg var at the end just to keep the liver stress down since your already running a decent amount of gear. hope u hit that 300 man!!
