How long does it take Primo to take effect on the body...Let's say I was running 500 mg's a week ofcouse along side with prop how long generally does it take to start working...basically is it fast acting like prop or you have to wait like decca...the reasons concearning this are I am running Var towards the end of my cycle at 70mgs for 5 weeks and wanted to put Primo in for maybe 2-3 weeks just to help harden up..at around 500mgs.. thanks bros..
Speed.
