You can mix the 2 into one shot, but like gtbro said it may hurt a bit. If it does hurt a bit too much, try cutting it with some sterile oil or b12. Also, what are your goals with this cycle?
Here is an example of how you can run it. It's a pretty rough layout IMO because I don't know your history or what kind of doses you are thinking of nor the goals of the cycle. Let me know and I'll do a little better, but if this is all you need then that's great too.
wk 1-12 prop 100mg/eod
wk 1-8 or 12 tren-a 50mg/eod
wk 5-12 winny 50mg/ed
wk 1-12 arimidex 0.5mg/eod
