hell yea it does, thing is deca can take 3-4 months to get out of your system which i am learning right now the hard way. so think about running your pct later. also get some proviron if you can
What they said and the fact that deca is one of the hardest AAS to recover from. So stopping it 2wks before you end your test is wise in 2 aspects not just one. Your recovery will be easier so do it, and stop asking questions! lol. j/j
Deca lasts more than sustanon, if you dont discontinue deca before, youll have only deca acting in your body at the end of the cycle, youll likely experience temporary impotence (deca-dick) as a result.
