Prop+grapeseed=relief?

guys, just ordered some sterile grapeseed oil to try and relieve some of the ridiculous soreness i get as a result of the prop im shootin.
can someone please recommend an amount of oil to cut the prop with...and also how exactly i should load them both into the one syringe. should i load the prop first or the oil? should i change pins or can i use the same one to draw from both (the prop and the g-oil) vials, and the put a freshy on to shoot with?
i appreciate any and all comments and or help anyone can offer.
thanks.

If I were doing it I'd cut it .5cc:1cc so if you wanted 1cc of prop then cut it with .5cc oil. Try that and see if it helps you out. If you think it needs more then go to 1:1. It doesn't really matter which you draw first, personally I'd go with the oil but it's not very important. I also wouldn't change pins between drawing from each vial but would change it to inject. Other opinions may vary there is certainly more than one way to go about this.

Appreciate it brotha...bump for anyone else's opinion...???
