Test Propionate before Test Cypionate?

[DrakeSwisher]

I have 3, 10m/l vial of propionate coming in about two-three weeks along with winstrol tabs. My buddy ordered cypionate and has an extra vial he is trying to get rid of. While waiting on the propionate, could I start on the cypionate now and just start the propionate when it gets here? I have seen people take propionate before taking cypionate but never the opposite. I have my ai in hand and my nolva for pct. just wondering if this would be okay to do?
thanks!
