I started the Nasacort a few days before I started the Tren, so by the time I started it was already working and I never developed any breathing issues at all. I can't say how long for it to help if you've already been running Tren for a while. It takes a few days for it to build up in your system, so I would guess it should start to help after a few days. I just can't be sure. Keep track of how you feel and how you're doing with cardio and let us know how long it takes to start noticing a difference. You get to be the guinea pig for this part, bro.
