Defiantly agree with keeping ai on hand and ready to go. Don’t want to have to wait 2-4 weeks to get some after a problem starts. As for deca with tren I’d go one or the other. I find tren to be better personally to cut because no matter what I eat I’m still super lean on it. Deca just makes me sleepy 24/7 for some reason. I agree with NPP less water weight so not a dramatic drop after you come off cycle
